The brushed aluminum sheet has alloy from 1000 series aluminum to 6000 series aluminum, they are brushed aluminum sheet alloy 3003, brushed aluminum sheet alloy 1100, brushed aluminum sheet alloy 6061 and brushed aluminum sheet alloy 5052.The brushed aluminum sheet alloy 1100 3003 5052 6061 has the characteristics of each aluminum alloy, but the performance is better than ordinary aluminum sheets.
We have know that the brushed aluminium sheets is manufactured by repeatedly scraped process out by the sandpaper with using aluminum sheets as the raw material. The process flow is mainly divided into three parts: de-esterification, sanding machine and water washing. In the aluminum brushing process, the special film technology after the anodizing process can form a film layer containing the metal component on the surface of the brushed aluminum plate, clearly showing each fine silk mark, thereby making the fine matte silky luster in the metal matte. The brushed aluminum sheet alloy can be choose-able according to the specific application, and also the price is different too.

1. This is the problem of mildew of aluminum alloy. Quicklime can be placed in the stacking place. Due to the humidity of warehouse air, the oxidization phenomenon can only make the warehouse environment dry and ventilated. In fact, this phenomenon often occurs in aluminum plate manufacturing enterprises
Aluminum alloy in open or semi-closed is very easy to oxidize, mildew, so must be done protection.
4 d & _5 ~ (B B ‘; ` ([in view of the product has oxidation, cleaning can be done to oxidation, and make protective treatment.
2. After the test and analysis, the experts found that the defect of aluminum alloymaterial is the main reason, and the extrusion — heat treatment process is unreasonable. If we want to solve the problem fundamentally, we need to strictly control the chemical composition of aluminum alloy. At the same time, the ingot was treated by homogenizing annealing as much as possible, and the ingot was cooled by rapid cooling.

checker plate aluminium sheet is among main products of Haomei. Our diamond plate used to take a large share of North American market. In spite of high import taxes, some clients still keep contact with us. Speaking of aluminium chequer sheet application, most people think of anti-skid floors in buildings, elevators, stairs and vehicles. It’s less well-known that tool box industry is also a large consumer. A tool box refers to a container for various tools in production, maintenance, fishing etc. Aluminum tool boxes are usually made of checker plate aluminium sheet alloys containing silicon or magnesium. They win wide popularity in packing because of reasonable design, delicate processing, strong loading ability and neat outlook. The boxes first caught fashion abroad and was later introduced into China with higher demands of product integrity in packing and delivery.

| How can aluminum foil, a metal, be in a 375-degree oven and not be hot to the touch? |

It can’t. But the foil is no longer at 375 so it doesn’t feel very hot.
Aluminum is a good conductor of heat but thin foil is does not hold much heat energy and it has a large surface area. Because of this the 375F drops away very rapidly so by the time you touch it, it has already lost enough heat to not feel too hot.
If you want to test this theory you could heat water in a pan to 120F then make a cover a finger with a watertight layer of aluminum foil. If you dip your finger into the water it will feel hot, when you remove your finger the heat rapidly disappears.

| Is it ok to use aluminimum foil with discoloration? |
|

No, because the discoloration means that the suface of the aluminum foil is destroied. The oxidation film on the surface of aluminum foil can prevent aluminum foil form corrosion and keep it safe when contact with food.
The discoloration means that the oxidation film is damaged, it is not safe any more, so do not use it to warp food or cooking with it any more.

ranks the first among aluminum foil products. Other relative products include cigarette foil, air conditioning foil, foil container foil, transformer foil etc. Kitchenaluminium foil is mainly used for food wrapping and packing for various purposes like barbecues, picnics, baking, cold preservation etc. Its raw material is 8011 aluminum, leading alloy for all kinds of aluminium foil sheets. 8011 belongs to 8000 series of aluminum, with a Si content of 0.5% to 0.8%, Fe content 0.6% to 0.9 and a slight content of micro elements. Obviously it has more impurities than 1000 series of aluminum like 1060. Owing to the fact that its content of other elements surpasses 1%, 8011 aluminum shows better properties as foil sheets. Its usually processed into foil rolls rather than sheets or plates.
![[Image: aluminiumfoilstrip-300x300.jpg]](http://www.aluminiumstrip-hm.com/wp-content/uploads/2018/02/aluminiumfoilstrip-300x300.jpg)
Under O state, 8011 has excellent performances as a kind of kitchen aluminium foil. It’s of such a good insulation effect that you will find wrapped food still fresh and warm after a long drive to a picnic destination. It’s able to withstand high pressure, and thus is frequently applied to wrap food which will later be put into a microwave oven or a baking oven. It’s so pleasant to gaze at hot mini cakes out of the oven on little wrinkled foil trays. Aluminium foil sheets are clean and healthy, containing no toxic materials. It can be as thin as 0.009mm, namely 9um like a thin paper.

| Why does the price of an aluminum strip for a transformer winding low in the market? |

aluminum strip transformer windings are suitable for low voltage (hundreds of volts), high current (hundred amps to thousands of amps) transformer, and are commonly used as secondary windings for distribution transformers. The foil type transformer adopts high conductivity copper foil strip or aluminum strip as the conductive material, and the thickness of the copper foil or aluminum strip foil is about 0.1 to 2.5 mm. The aluminum strip for transformer winding price is lower than copper foil price, so, the aluminum strips occupy more market in transformer enterprises.
![[Image: aluminum-strip-19-300x300.jpg]](http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/04/aluminum-strip-19-300x300.jpg)
We all know that, the conductivity of copper foil is higher of aluminum foil, but why more and more customers prefer aluminum foil strips than copper foil is not just because of saving coat. Moreover, for the dry type transformer, since the thermal expansion and contraction coefficient of aluminum is closer to the thermal expansion and contraction coefficient of the epoxy resin than the copper, the crack resistance of the aluminum strip for transformer winding is better than that of the copper. Moreover, since the strength of the dry transformer winding itself is very good, the difference in mechanical strength between copper and aluminum has no practical significance. Due to using the 1000 series aluminum, the aluminum stripfor transformer winding price on the market is not high, 1060 and 1070 aluminum strips with round edge and no burr are good choice to processing dry type transformer winding.

Aluminum wafers , we also called it as Aluminum circle is a common seen aluminum product and has wide application. There are many industries need aluminum wafer to do future process, so the quality of aluminum discs product is the premise of the whole produce line. In order to guarantee the quality of aluminum wafer, we should know the producing process of it first. Take 1070 aluminum circle as an example, firstly, the aluminum ingot with 99.7% aluminum content are smelting into aluminum liquid in high temperature furnace, then transfer into holding furnace and remove the slag, next, the aluminum liquid flows into the casting furnace ready for casting, and then through hot rolling, cold rolling, shearing, punching and other craft, at last, the aluminum wafer is processed from aluminum roll by stamping forming.
![[Image: 016-300x300.jpg]](http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/07/016-300x300.jpg)
So, while choose aluminum circle manufacturer who can provide qualified product, there are some aspects can be considered, such as product specification, processing technology, whether they have factory and professional equipment, whether they have experienced technician, whether the producing progress is strictly controlled. When you have checked these aspects, you can judge the supplier clearly to do the right decision. Haomei aluminum is an enterprise specialized in producing aluminum discs and other aluminum alloy products, we have adopt advanced processing equipment which can improve the production efficiency and material utilization effectively and short the delivery time.
