ALUMINUM ALLOY POWDER FORMULATIONS WITH SILICON ADDITIONS FOR MECHANICAL PROPERTY IMPROVEMENTS

摘要

An improved aluminum alloy powder metal includes silicon additions. When this improved powder metal with silicon additions is sintered to form a sintered component, the resultant component exhibits many improved mechanical strength properties and improved thermal resistance.
