aluminum-silicon hypereutectic alloy

Aluminum Alloy for High Temperature Applications A novel low cost cast aluminum alloy offers dramatic strength at high temperatures NASA's Marshall Space Flight Center originally developed a high-performance piston alloy to meet U.S. legislative restrictions on vehicular exhaust hydrocarbon emissions. NASA 398 aluminum alloy exhibits excellent tensile and fatigue strength at elevated temperatures. NASA 398 alloy also...

aluminum-silicon hypereutectic alloy

Executive summary

ASA 398 is an aluminum-silicon hypereutectic alloy (16% w. Si) with a microstructure that consists of small polygonal primary silicon particles evenly distributed in an aluminum matrix. The alloy can be utilized in automotive applications with high mechanical loading at elevated temperatures from 500 F (260C) to 700 F (370C), and can offer significant improvements in strength relative to most conventional aluminum alloys. Material physical and mechanical properties for NASA 398-T5 (permanent mold) are provided in Table 1 below.
