When is aluminum the optimum choice for a die cast part?
A. Aluminum (Al) die casting alloys have a specific gravity of approximately 2.7 g/cc, placing them among the lightweight structural metals. The majority of die castings produced worldwide are made from aluminum alloys, with good corrosion resistance and good mechanical properties. Aluminum die castings offer high dimensional stability, thermal and electrical conductivity, and strength at high temperatures. Aluminum 380 alloy is the most widely used of the Al die casting alloys, offering the best combination of properties and ease of production. For detailed information on Aluminum Alloy Properties, die casting, and post-casting characteristics, consult the NADCA Product Design Sourcebook or NADCA Product Standards Manual. Both are available from your CWM Sales/Engineering Representative or directly from CWM (See descriptions & Discount Order Form). Specific alloy data is also available in the Resource Center Engineering Bulletin section, described and available for instant download, o
