Defects not allowed in hot-rolled aluminum alloys

What are the types of defects of hot-rolled aluminum alloys?

Defects refer to the defects in aluminum alloys, or imperfections, which will have a bad impact on the user's use.

According to the impact of defects on the quality of aluminum alloys, they are divided into three categories

1. Defects that are not allowed,

The occurrence of these defects means that the product is absolutely scrapped.

These defects include loose organization, penetrating pores that destroy the bonding force between grains, casting coarse impurities, overburned waste;

Corrosion that destroys the corrosion resistance of the product, slip line waste;

Fission cracks that destroy the overall structure of the product;

Unqualified mechanical properties that exceed the use requirements and standard requirements, too thin, too thick, too narrow, too short.
