Haomei supply prime quality sheet aluminum 4×8 with alloy of 1060 aluminum sheet, 1050 aluminum sheet, 1100 aluminum sheet, 3003 aluminum sheet, 5052 aluminum sheet, 5083 aluminum sheet and 6061 aluminum sheet. The higher the purity is, the better the corrosion resistance is. The main reason is that pure aluminum plays a role in neutralizing oxygen in the air. A very thin and very dense natural oxide film is produced on the surface of aluminum, which is faster and much thicker than other metal oxide films. Although it prevents the further corrosion of harmful gases and water in the air, it still plays a role in protecting Protective effect.

In general, if you want to buy sheet aluminum, you should pay attention to the following three points to ensure the high quality.

1. It is to see whether the aluminum sheet 4×8 has obvious distortion, whether the surface is smooth and flat, whether there is crack or boldness, scratch, burr place, if found, it is better not to buy.
2. A smooth hard object can be used to scratch the surface of the aluminum sheet, which will leave a white scratch. The aluminum sheetis gently wiped and observed by hand. If it cannot be wiped off, it indicates that the material may have quality problems, but on the contrary, if it can be easily wiped off, it indicates that the thickness of the oxide film on the surface of the profile is qualified.
3. Be sure to check the surface color of sheet aluminum 4x8carefully to see if there are color differences of different shades. If there are color differences, it means that the quality is not up to standard. Of course, you can also put the same type of profiles together for comparison. If the color difference is too obvious, you’d better not choose. Also check whether the section thickness of the sheetaluminium is consistent with the model marked.

For the sheet aluminum 4×8 in the market, we can use a simple method to identify the alloy aluminum plate, in order to have a better experience in use.
