Abstract

A process for hardening aluminum comprises the steps of adding a magnesium hardener to molten aluminum wherein the hardener has a magnesium content in the range of 64-72 wt % based on the weight of the hardener, with a remaining portion of the hardener comprising aluminum. The process may further include the steps of preheating the hardener prior to adding the hardener to the aluminum for decreasing a temperature differential between the hardener and the aluminum so as to stabilize the hardener and prevent shattering thereof.
