AN ALUMINIUM-BASED ALLOY COMPOSITION, A METHOD OF MANUFACTURING ALUMINUM-BASED ALLOY CASTING, AND ARTICLE MANUFACTURED THEREOF

摘要

The disclosure relates to technology of castable aluminum alloys, more particularly relates to designing the aluminum alloy composition for enhanced mechanical properties by squeeze casting and heat treating the Aluminum alloy. The alloy composition comprising copper ranging from 1.5% w/w to 3.5% w/w, silicon ranging from 6% w/w to 12.0% w/w, iron ranging from 0.0 % w/w to 1.3% w/w, manganese ranging from 0.0 % w/w to 0.5% w/w, magnesium ranging from 0.0 % w/w to 0.3% w/w, zinc ranging from 0.0 % w/w to 1.0% w/w, and nickel ranging from 0.0 % w/w to 0.5% w/w. Further, provides for method of manufacturing an aluminum-based alloy casting of said composition, comprising acts of preparing molten metal from aforesaid composition, applying predetermined pressure onto die comprising the molten metal to squeeze cast the molten metal, and extracting the casting from the die and heat treating the casting to manufacture the casting.
