  PRIMARY ALUMINUM ALLOY (HIGH GRADE)

Primary Aluminum Alloy is a type of aluminum alloy with low Fe content

This type of aluminum is commonly used in aluminum casting for car wheels, motorbike wheels, aluminum anodes, etc. Primary aluminum Alloy is made of pure aluminum and several mixed elements. For customers who do not have a composition specifications, PT. Altikamurni Internusa has a reference based on Standart dized chemical composition generally used in Indonesia. The following is a reference table of chemical composition that we use in aluminum manufacturing:
