  SECONDARY ALUMINUM ALLOY (MEDIUM GRADE)

Secondary Aluminum Alloy is a type of aluminum alloy with high Fe content

Secondary Aluminum Alloy is made of base metal and aluminum scrap for the needs of the casting industries, such as automotive spareparts (machine components, brake levers, pistons) and other aluminum castings.

For customers who do not have their own composition specifications, PT. Altikamurni Internusa has a reference based on the Standart dized chemical composition generally used in Indonesia. The following is a reference table of chemical composition that we use in aluminum manufacturing :
