Aluminum plate can be divided into different alloy grades according to the different alloying elements, different alloy grades of aluminum plate has a different range of applications.Today we explain to you guys what is the difference between 7075 aluminum plate ,6063 aluminum plate and 6061 aluminum plate?
1：Different alloy composition
6063 aluminum plate and 6061 aluminum plate is belongs to 6 series aluminum plate,6 series is aluminum, magnesium, silicon alloy, 7075 aluminum alloy elements is Aluminum and zinc.
6061 aluminum and 6063 aluminum plate is more subtle differences, the silicon content of the first one is between 0.4 and 0.8.Magnesium content in 0.8-1.2. But 6063 silicon content in 0.2-0.6, Magnesium content 0.45-0.9. Because of silicon and magnesium content. General said 6061 in terms of hardness is better than 6063. 6061 and 6063 have a great difference in the tensile strength. As the annealing and quenching is different, both in the same condition the former tensile strength is less than or equal to 150-290 and the latter is less than or equal to 135-240.
What is the difference between 7075 aluminum plate ,6063 aluminum plate and 6061 aluminum plate?
2 ifferent product uses
6061Aluminum plate requires a certain strength, higher resistance to the various industrial structure. Such as the manufacture of trucks, tower buildings, ships, electric cars, furniture, machinery parts, precision machining, such as the use of tubes, rods, shaped wood, sheet metal.
6063Aluminum plate for building profiles, and irrigation pipe for vehicle, bench, furniture, fences etc. with the extrusion materials.

Aluminum plate, as the name suggests is made of aluminum or aluminum alloy material made of plate. Or by the flat aluminum embryo by heating, rolling and straightening or solid solution aging heat and other processes made of plate aluminum products.
Do you really understand the aluminum plate?
Aluminum used in the building, including single-layer aluminum, composite aluminum and other materials, generally refers to the single-layer aluminum (also called a single aluminum or pure aluminum), used in architectural decoration works, in recent years in the aluminum curtain wall single-layer aluminum The more common. Aluminum curtain wall is also a form of curtain wall, simply made of aluminum instead of glass curtain wall, aluminum curtain wall used for wall protection and non-lighting walls. Such as the Guangzhou World Trade Center, on the use of the Southwest aluminum processing plant plate processing different arc of aluminum nearly 150 tons, the surface using electrostatic spraying. Foreign aluminum curtain wall has been selected single-layer aluminum. Single-layer aluminum plate is generally made of pure aluminum. Aluminum plate thickness of 3mm, in order to strengthen the aluminum plate surface strength, in the back of the aluminum plate, must be installed ribs (existing manufacturers uneasy), ribs made of thick aluminum, first with a flash welder to a screw cap Welded on the back of the aluminum plate and then put the ribs into the screws into the screws, fixed with screws.
China in order to reduce the weight of aluminum, aluminum plate strength, we use aluminum alloy plate, often use No. 21 rust-proof aluminum code LF21 pressed aluminum plate for the curtain wall aluminum. Aluminum plate thickness from the original 3mm reduced to 2.5mm, the strength of the alloy than pure aluminum about twice. Reinforcement with LF21 aluminum belt, the width of aluminum tape thickness depends on the aluminum plate, generally thick 2-2.5mm, width 10-25mm. Aluminum curtain wall of the back of the aluminum Why should the installation of stiffeners, is the case of positive and negative pressure in the outside, the aluminum will not be a depression, two will not bulge, so to avoid the aluminum wall and repeated vibration inside and outside the vibration sound. If you need insulation, can be inside the aluminum plate, placed rock wool, slag cotton or foam treatment.
China's first production of aluminum curtain wall aluminum manufacturers, Chongqing Southwest aluminum deep processing plate, the plate for the military manufacturers, the production of aluminum plate width can reach 2.8 meters. Curtain wall aluminum surface treatment, can be divided into two methods, one is anodized, the other is electrostatic spraying. Anodized oxide film is generally more than 12μ, the color is only bronze and white two, color monotonous, more serious shortcomings is the color of each piece of aluminum plate color varies, many pieces of curtain wall panels together to form a curtain wall overall effect Very ugly. This shortcoming can be said that can not be eliminated, not the production technology, but because the aluminum plate is not a batch number, chemical composition, there are small differences, coupled with oxidation when the electrolyte current density and other factors can not be exactly the same, so oxidation of the color of how many are different, leaflets may not be obvious, if all together is very obvious. So the aluminum plate curtain wall aluminum surface treatment, must not be used anodized.

The main alloy element of 6061aluminum plate is magnesium and silicon, with moderate intensity, good resistance to corrosion, excellent oxidation effect. 60621 aluminum plate is widely used after heat treatment, for automated machinery parts, precision machining, all kinds of mold manufacturing.
6061 aluminum plate commonly used states:
T6 state of 6061 aluminum alloy is the most used, forming process including medium thickness plate quenching, medium plate section, drawing machine, aging treatment, sewing machine, polishing, packing.
The whole production cycle isabout 10 days. After heat treatment, It doesn’t need to be cold, but can be straightened, leveling,not affecting the mechanical properties.
F state is freedom of 6061 aluminum alloy processing, applied to the process of forming, the strain hardening and heat treatment conditions of special products.F state production cycle is short: medium thickness plate section, sewing machine, polishing (also is not polished, according to customer's requirement) - packaging, the entire process to arrange 3 days can be shipped smoothly. F state mechanical properties do not have strict specifications, customers according to their own needs can be heat treatment processing, the F state again the state into production use. Corresponding to the price is the cheapest.
O state is to obtain the minimum strength of 6061 aluminum alloy after annealing completely processed products, applied to the 6061 aluminum alloy sheet under 8.0mm. Its production process: cold rolling thickness - bent proper cleaning - full annealing - fly shear piece of stretch bending pose (or out of the finished product) - packing warehousing and so on a series of production, production cycle after T6 state.

Food packaging bags can be used in a variety of materials, including a variety of functional plastics, paper and aluminum, etc. Many people find it strange why aluminum can make food packaging materials? What are the characteristics of food packaging bags made from aluminum? Today, we with everyone together to explore.
Aluminum used in the production of food packaging bags are usually made of aluminum foil and other materials. There are two main reasons why this works.
Why can aluminum foil make food packaging bag?
First, the composite process requires that the composite substrate must be sheet shape, while the metal aluminum can be easily processed into sheet material due to its low hardness and good ductility. The thickness of aluminum foil is 0.005 mm~0.009mm.
Second, the aluminum nature is very lively, very easy to be oxidized by oxygen in air, forming a layer of dense oxide Al2O3 protective film on the metal surface, the nature of Al2O3 in air environment is extremely stable, can prevent further oxidation of aluminum oxygen. Of course, the use of aluminum foil bags made of this layer of dense protective film can be a good way to isolate the outside air into the bag inside, to prevent the role of food oxidation deterioration.

At present, China is the world's largest producer and exporter of aluminum foil, aluminum foil production and processing technology and equipment have reached world-class, product quality also reached the international advanced level. However, the domestic market is still at a low level of aluminum foil packaging applications, aluminum foil lunch boxes and containers.
Research shows that 21% of people believe that the long-term use of aluminum foil will be poisoned, and 18.3% of people think that aluminum foil products belong to the high price of high-end products, and 11.3% of people think that aluminum foil lunch boxes are excessive consumption, waste of resources. A considerable part of the consumer and food and beverage business managers have a misunderstanding that aluminum containing heavy metals and other harmful substances, the impact of the concept of aluminum foil box sales limit. In fact, there is a layer of dense oxide layer on the surface of aluminum foil, the chemical properties of the oxide layer is relatively stable, only in the environment of strong acid will precipitate aluminum ion.
Global aluminum foil manufacturers initiative Chinese coordinator Dong Chunming introduction, compared to other materials, lunch boxes and containers, aluminum foil as a lunch box and the advantages of many. First of all, aluminum foil can be very safe to contact with food, does not contain or help bacteria grow. Second, the aluminum foil has a good thermal stability, in the 20 - 250 C high and low temperature, the molecular structure is stable, no deformation, no crack, no melting. With high temperature aluminum foil separated fire and smoke, but also can effectively avoid the carcinogenic food for the burnt. Three aluminum foil can completely block light, gas and other substances, to extend the preservation and protection of water, to maintain the original flavor and characteristics of food.

Alloy 5086 aluminum plates have even higher strength than 5052 or 5083 and its mechanical properties vary significantly with hardening and temperature. It is not strengthened by heat treatment; instead, it becomes stronger due to strain hardening or cold working of the material. This alloy can be readily welded, retaining most of its mechanical strength. The good results with welding and good corrosion properties in seawater make Alloy 5086 extremely popular in marine applications. Alloy 5086 has been used in vehicle armor plate due to its high strength factor.
5086 aluminum plate has higher strength than 5052 plate and 5083 plate. Coupled with excellent corrosion resistance, 5086 plate is particularly salt water corrosion resistance.
