Different types of aluminum alloy products

Casting of the aluminum alloy product
Cast aluminum alloy product is an aluminum alloy used to directly cast mechanical parts of various shapes. According to the main elements added, it can be divided into Al Si alloy, Al Zn alloy and Al Mg alloy. Each system has its own brand, which is more complex.

Difference of the aluminum alloy product
The fundamental difference between wrought aluminum alloy and cast aluminum alloy can be explained by aluminum based binary alloy phase diagram: the alloy whose composition is located to the left of point B 'belongs to wrought aluminum alloy. When heated to a temperature higher than the solution line (BD), it can obtain single phase α Solid solution has good plastic workability and is suitable for cold and hot pressure processing. Due to the development of melting and casting technology, the composition of some deformed aluminum alloys has been expanded to point F. The alloy whose composition is to the right of point e belongs to cast aluminum alloy. Because its structure contains eutectic with low melting point and good fluidity, it can prevent hot cracking and is suitable for casting. It can be seen that the component content of cast aluminum alloy is higher than that of deformed aluminum alloy. Aluminum alloy can be divided into heat treatment strengthening and non heat treatment strengthening. The alloy whose composition is to the left of point D, the composition of its solid solution does not change with the change of temperature, there is no phase change during heat treatment, and there is no strengthening, which is called non heat treatment strengthened alloy; The composition of the solid solution of the alloy with the alloy composition between DF changes with the temperature, that is, the phase changes during heat treatment, so it is strengthened, which is called heat treatable strengthened alloy.(aluminum alloy product)
