Aluminum powder​ ___ Aluminum powder is spherical metal powder produced by nitrogen atomization Spherical aluminum powder is widely used in crystalline silicon solar cell back field aluminum paste, aluminum pigment, refractory, composite steel pipe, aluminum nitride ceramic materials, powder metallurgy products, spraying materials, 3D printing materials, etc. According to the different needs of customers, there are 99.5, 99.7, 99.8, 99.9, 99.99 and other products with different thickness specifications. Aluminum is reductive and easy to be oxidized. Therefore, aluminum and aluminum alloy powder should be sealed and isolated from air to prevent oxidation. It can be placed in the sealed tank indoor, and the storage temperature is 15 ~ 40 ℃. Avoid direct exposure to sunlight, rain or high temperatures.
