the purchase of industrial aluminium sheets

In the purchase of industrial aluminium sheets, there are very many selection techniques that only a connoisseur can understand. If a novice doesn't understand it, he or she may buy aluminium plates that are not suitable when they are. So what do we have to pay attention to when selecting industrial aluminium plates? Let's take a look together today! The next Haomei Aluminium will introduce you to several factors that we should mainly focus on.

The first thing we need to look at is the hardness. Many customers are very concerned when buying aluminium, the hardness is preferred to have a direct relationship with the chemical composition of the alloy. Secondly, the different states also have a greater impact, from the highest hardness that can be achieved, 7 series, 2 series, 4 series, 6 series, 5 series, 3 series, 1 series, in descending order.

The next thing we need to look at when choosing an industrial aluminium sheet is strength: strength is an important factor that must be considered when designing a product into its aluminium alloy component as a component, and the appropriate alloy should be chosen according to the pressure it is subjected to. Pure aluminium has the lowest strength, while 2 series and 7 series heat treatment type alloy degree is the highest, hardness and strength have a certain under phase relationship.

Another very important point when selecting industrial aluminium sheets is corrosion resistance: corrosion resistance includes chemical corrosion, stress corrosion resistance and other properties. Generally speaking, 1 series pure aluminium has the best corrosion resistance, 5 series has good performance, followed by 3 series and 6 series, 2 series and 7 series are poor. Corrosion resistance should be selected according to the principle of its use. For use in corrosive environments with high strength alloys, various composite materials for corrosion protection must be used.
