7A04 super-hard aluminum ingot ¦Õ456mm produced in Guoxin Aluminum Company

Recently, the 7A04 super-hard aluminum ingot ¦Õ456mm was produced in Qinghai Guoxin Aluminum Industry Incorporated Company, it is another progress that the company made after the success in the production of 100MN extruder casting debugging large diameter ingot.

Different from the other ingot, the super-hard feature of the new ingot are more tend to crack. So the technological parameter was particularly important in the process of production. The operation should not only avoid the spill of the aluminium in liquid condition at the beginning, but also should take the tempering processing technology of highly difficult.

After the examination, it is proved that both the surface quality and internal processes of the ingot have met the technical requirement.
