Abstract

Possibility of using of aluminum A7 instead of A8 to reduce the cost automobile wheel discs, made from alloy AK12 by casting under low pressure is studied. The microstructure and properties of six experimental alloys are investigated. It is found that use of primary aluminum A7 instead of A8 is possible at insertion of a compensator element-manganese in an amount of not more than 0.20–0.25 wt %. at the content of iron is not more than 0.20-0.25 wt. %, that is ratio Fe: Mn has to be equal 1: 1. The mechanical properties demanded GOST 50511-93 are received
