How To Obtaining Aluminium Foil Sheet Thickness Posted by: ZellaHyday - 07-10-2018, 07:39 AM - Forum: aluminium faq - No Replies If you can not find out from the manufacturer. Understanding how aluminium foilsheet is measured is the first step to obtaining foil thickness. [img=574x0]http://www.aluminium-foil.org/wp-content/uploads/2017/03/how-to-obtaining-aluminium-foil-sheet-thickness.jpg[/img] Aluminium foil rolls and sheets come in a variety of thicknesses, widths, and lengths. Manufacturers often make the width and length of the foil roll easy to find, but the thickness of the foil is often not advertised. Most manufacturers use terms like standard duty, heavy duty, and extra heavy duty to describe foil thickness. Finding the actual thickness from a foil box or manufacturers website is not likely. Let’s look at some common foil sheet thicknesses and the best way to measure for finding foil thickness . 1 Mil = 1 Thousandth of an inch. 1 Mil Numerically = .001 Household aluminium foil are often between 75 ft. and 250 ft. long, offered in a variety of widths. The majority of foil rolls labeled as “Standard Duty” are between .0004 thick and .0007 thick. Which at best is slightly over or one half of a mil in thickness. By far the most common aluminium foil sheet used for home and commercial use. Most home users buy 75 ft. rolls of Reynolds aluminum foil or a comparable brand for home use. Heavy duty foil provides extra strength and tear resistance. Many cooks use it for baking, grilling, and storage. Most Aluminum foil rolls labeled “Heavy Duty” are between .0008 thick and .001 thick. The extra three thousandths of an inch makes a big difference for a variety of applications.   What Is Aluminium Foil Tape Technology Posted by: ZellaHyday - 07-10-2018, 07:35 AM - Forum: aluminium faq - No Replies Aluminium foil applications more and more widely. Let us have a look at the following aluminium foil tape, what is aluminum foil tape technology? [img=600x0]http://www.aluminium-foil.org/wp-content/uploads/2017/03/what-is-aluminium-foil-tape-technology.jpg[/img] Aluminium foil tape uaually used for a variety of transformers, mobile phones, computers, PDA, PDP, LED monitors, notebook computers, copiers and other electronic products within the electromagnetic shielding of the place. Aluminium foil tape with high-quality pressure-sensitive adhesive, good viscosity, strong adhesion, anti-aging effect!

Product explanation of aluminium foil tape: Purity higher than 99.95%, its function to eliminate electromagnetic interference ,isolated electromagnetic waves on the human body damage, to avoid the need for voltage and current and affect the function. In addition, for the electrostatic discharge after grounding has a good effect. Material for the multi-ester fiber, after repeated use or multiple bending are less prone to cracks and damage. Paste strong, good electrical conductivity, can be easily wrapped in the wire, according to customer requirements cut into a variety of specifications.   Factors Affecting the Quality of Aluminum Coil Posted by: ZellaHyday - 07-09-2018, 07:44 AM - Forum: Knowledge & Technique - No Replies 1. alloying elements 6063 aluminum alloy coil  is aluminum and magnesium as the main element of the preparation of the alloy, each element has a certain range of content, magnesium prices are high.Other manufacturers in order to reduce costs, the amount of magnesium to the minimum allowable content. Some of the worse, the content of magnesium below the minimum allowable content. There are plants in the alloy plus waste wire and waste basin waste aluminum pot, the basic talk about 6063 alloy. Resulting in aluminum mechanical strength is very low, can be low to use both hands bent is easy to bend, commonly known as noodles as soft. This is why aluminum can be a few thousand dollars cheaper one reason.   2. Aluminum alloy melting furnace With the 6063 alloy how to melt, what stove, which is also essential, and now the domestic use of the stove has 40 years level, there are 90 level, the worst manufacturers with the original crucible boiler. There are burning, burning, burning and electric heating smelting furnaces. Some stoves have chimneys, some stoves without chimneys. Generally used for the square furnace (rectangular furnace), advanced for the round furnace, and some round furnace can be tilted pour aluminum water. On tonnage there are tons, two tons, five tons, ten tons, twenty-five tons and fifty tons of molten aluminum furnace. More advanced, in the melting furnace below the addition of a static furnace, standing furnace important preparation 6063 alloy, can be in this furnace in addition to slag removal, standing, and then cast aluminum rods, aluminum ceiling for extrusion use. In the original coal burning furnace and modern round furnace prepared alloy quality, absolutely not the same. General furnace, regardless of what fuel burns, should have a chimney, the fuel in the combustion process to produce most of the waste residue can be discharged from the chimney. Such as no smoke tube exhaust waste all melting aluminum water, so cast for extrusion with aluminum rods, the existence of a serious internal slag bubbles, which is one of the reasons for the poor quality of aluminum, aluminum is one of the reasons for cheap. Color coated aluminum roll     I believe we read the above explanation must affect the aluminum rolled aluminum several elements have a certain understanding. I hope you will choose aluminum when the future will take these factors into account.   Development trend of aluminum alloy coil in China Posted by: ZellaHyday - 07-09-2018, 07:37 AM - Forum: Knowledge & Technique - No Replies In recent years, Chinese market demand for industrial alloy aluminum volumes, due to industrial aluminum alloy with a light weight, corrosion resistance, easy to shape, recyclable characteristics, in China stressed the premise of energy saving and environmental protection, industrial aluminum coils in the transportation, home appliances , Electronic and mechanical equipment and other areas of the application of a large increase to aluminum gradually replace steel, copper and other traditional metal materials to become the development trend. In the process of leap-forward development of China’s railway, lightweight is the main way to achieve high-speed heavy load. In China, the transportation of bulk raw materials mainly depends on the railway, aluminum alloy sheet in the railway coal truck on the application of unlimited potential, back to Shanxi Province to Hebei Province, Daqin line, for example, is the West China Coal to the coastal industrial area of the main channel One of the running on the aluminum alloy coal trains, and with the same weight, similar to the structure of the whole steel train, not only the body weight reduction of five tons, but also can achieve each vehicle weight increase of five tons of the target. Today, almost all of the international car brands have increased the development and application of aluminum alloy materials. What is the energy saving effect of the aluminum industry in the automobile industry? The research data show that reducing the weight of the transport tool is an effective way to reduce fuel consumption. The use of high strength steel in key auto parts can only reduce the weight of aluminum coil; Can reduce the car into the weight of four percent. In addition to low-carbon energy, aluminum coil also has a strong impact performance, can absorb the collision energy is twice the steel plate   Aluminium Sheet, Aluminum Plate for Building Decoratio Posted by: ZellaHyday - 07-06-2018, 09:06 AM - Forum: Buying Leads - No Replies [color=rgba(0, 0, 0, 0.87)]Aluminium Sheet, Aluminum Plate for Building Decoration, Traffic Sign manufacturer / supplier in China, offering Standard 3003/5005/5052/5083 /6061 Aluminum Alloy Sheet /Plate, LED Aluminum Strip Light, Aluminum Checkered Plate Tread Plate Floor Plate 1050 1060 1070 and so on.[/color] [color=rgba(0, 0, 0, 0.87)]We are in a good position not only to supply you high quality marine aluminum product , but also the excellent after sales service.[/color] [color=rgba(0, 0, 0, 0.87)]More details, just feel free to contact me![/color] [color=rgba(0, 0, 0, 0.87)]wade[/color] [color=rgba(0, 0, 0, 0.87)]Email:wade@haomeicn.com[/color]   Why does aluminium foil keep food warm? Posted by: ZellaHyday - 07-06-2018, 07:19 AM - Forum: aluminium faq - Replies (2) Aluminum foil does not make food warm. It can keep food warm longer by trapping the hotter air inside, which then serves as an insulator, and by preventing interchange of the hot air inside with cooler air. Aluminum foil itself conducts heat very well so it isn’t an insulator itself. Instead it is a barrier that limits the mixing of the hot air inside with the cooler air outside. If you wrap the food with cotton napkins first and then with foil it will stay warm longer simply because the napkin holds the foil farther from the food, creating more space for insulating air.

Just turn on the air conditioner and within minutes you can feel the cold air around you. Apart from the various factors that determine which type of air conditioner is better, there is an age-old debate as to which type of coil is better – Copper or Aluminium. Before we see the pros and cons of each type, let us first understand the importance of these coils in the air conditioning process. Importance of coils in Air Conditioners The core to air conditioning is a refrigerant gas that goes from gaseous state to liquid state by compression and then again changes back to gas by absorbing heat available in the room. It goes through a refrigeration process that is mainly divided into 4 parts: Compression: The gas is pressurized and converted into a high-pressure hot liquid. Condensation: The liquid flows through a coil where the high-pressure hot liquid refrigerant is converted into cooler liquid by releasing heat into the outside air. This is a part where coils are used. Expansion Valve: A valve then converts high-pressure liquid to low-pressure liquid. Evaporation: The low-pressure liquid again goes through an evaporation coil where it absorbs heat from the room and changes from liquid to gas. This process happens in the indoor unit while all other happen in the outdoor unit (in case of split ACs). Coils Basically the heat from the inside air is transferred to outside air and this transfer of heat takes places in the coils. The refrigerant in the evaporation coils evaporates (changes from liquid to gas) by absorbing the heat from the air (air from the room) passing over it. The air (from the room) cooled in this process is directed into the room. The gaseous refrigerant is then passed through the compression process and condensation coils where the refrigerant condenses by releasing the heat into the air surrounding it. This warm air is blown out with  This working principle remains same in all types of HVAC systems; just the size of the system keeps on varying. Hence the type of coils used in them affects the efficiency of HVAC systems. The size of the coil, the material used to make them, their ease of cleaning and maintenance; all play a very major role in the functioning of the HVAC systems. History of Air Conditioner Coils In past the most popular choice for making these coils was copper. For many years only copper was used to make the coils in HVAC systems due to the various benefits it had, but that made air conditioner expensive and not everybody could afford them. By around 1970, General Electronics took a step that was a game changer for the air conditioning industry. The started using aluminium to make coils. The cost of using aluminium was much less than that of using copper, which brought down the subsequent rates of ACs making it a luxury that most people could afford. Since then there has been a debate about which material is better for making coils. Differences between Aluminium and Copper 1) Heat transfer characteristics: As the transfer of heat takes place in the coils, it is very important for the metal to have good heat transfer characteristics. Copper has a heat transfer coefficient higher than aluminium. That means, copper is a better heat exchanger than aluminium. 2) Cost and Pliability (The quality of being easily bent): Copper is costlier than aluminium, which increases the cost of making an air conditioner and thereby the price of air conditioner. To reduce the unit cost of manufacturing ACs, aluminium has become the favorite choice of manufacturers.   I have bought a 1.5 ton Voltas split ac with aluminium coil. What can I do? Posted by: ircasodle - 07-06-2018, 06:55 AM - Forum: aluminium faq - No Replies There is nothing wrong with aluminium coil. Future of Air Conditioner would be on aluminium coil. I will explain why people are often reluctant to buy ACs with Aluminium Condenser Coil. Basically ACs comes with two types of Condenser Coil - Copper and Aluminium Since these are placed outside and would have direct interation with atmosphere outside. Being a highly active material with coastal conditions, aluminium tends to corrode faster at such conditions. However, there are many advanced coatings are now available which will extend the life of coil. Also another disadvantage of Aluminium coils is , it is almost difficult to repair Aluminium coils if there is a bend or small hole is found. Whereas in copper, it can be repaired and joints can be welded. Other than above points, aluminium is much cheaper than copper and also have more area of heat transition as it comes as PFC (Fins and Tubes). — your AC is covered under warranty for 1 year. You can opt for AMC (Annual Maintenance Contract) with Voltas after 1 year which will cover your AC for warranty with minimal charges. Also if your area is coastal side or high with moisture content, Voltas itself will change your coil to Copper if required.   What is aluminium ore called and what is the chemical formula for aluminum oxide Posted by: ircasodle - 07-06-2018, 06:48 AM - Forum: aluminium faq - No Replies The ore is called "Bauxite". The chemical formula for Aluminium Oxide is Al 2 O 3 Note however, this is not the chemical formula for Bauxite. Aluminium dioxide (alumina) Formula. Aluminium dioxide, also known as aluminium (III) oxide, is an oxide found in minerals as bauxite and corundum. Alumina is commonly used as catalyst and adsorbent. Formulaand structure: The aluminium oxide chemical formula is Al2O3. Itsmolecular weight is 101.96 g mol-1.   Does aluminum have a chemical formula? Posted by: ircasodle - 07-06-2018, 06:45 AM - Forum: aluminium faq - No Replies Aluminum in itself does not have a chemical formula, because chemical formulas are only used for compounds, and Aluminum does not have a chemical formula - only a symbol (which can be found on the periodic table of elements).
