时间:2017年12月13日 17:23

Sometimes you don't understand why aluminum castings are whitish. What causes the whitening of aluminum castings? Let me talk about the causes of this phenomenon today.

It is white aluminum casting defects, we encounter such products must be careful not to be fooled by the supplier side. Let's talk about the cause of this kind of defect.

The reason for the whitening of aluminum alloy castings is that the position of these white spots can not meet the requirements of sealing, and usually appears in the thin wall. The reason for this problem is that in the process of crystallization, the shrinkage of the casting is not enough, or the location of the aluminum alloy fluid is not right. The improper solidification temperature or improper solidification speed will cause the above defects. Also, the edges of the aluminum alloy castings are large, or the cooling of the aluminum alloy castings is slow.
