Effect of Aging Time to the Commercial Aluminum Alloy Modified with Zirconium Addition

Article Preview

Abstract:

The influence of heat treatment condition with addition of zirconium on the some properties of aluminum alloy has been investigated. The composition of aluminum alloy cast produce from this research was supplied from the foundry. The cast alloys were given a solutionizing treatment at 520°C followed by artificial aging at 175°C for a different period of time up to 10 hours. Hardness of heat treated aluminum alloy then were determined by comparing to the as cast and natural aging alloy. The addition of zirconium will improve the properties of the alloy in term of hardness and conductivity. Grain size of alloy has no significant effect when aging time increased together with zirconium addition.
