NASA-427: A New Aluminum Alloy
NASA-427: A New Aluminum Alloy
The NASA-427 alloy, with its origins in the Ares rocket program, has high potential for use in a number of automotive applications, including cast aluminum wheels, control arms, steering knuckles, and other components. Why its Better This technology uses precise chemistry to improve the mechanical properties of cast aluminum products, which demonstrate substantial increases in impact toughness due to the improvement in tensile strength and ductility. The steps necessary to complete the thermal coating process proceed more quickly using this new alloy the heat treatment process is much shorter, and the aging process has been optimized in conjunction with the powder or paint-baked coating process. It also offers improved corrosion resistance meeting or exceeding the performance of A356-T6 alloy, as well as offering significant cost-savings over forging 6016-T6 alloy when elongation is less than seven percent. Because of its superior tensile strength coupled with significant process improvements, choosing NASA- 427 yields energy and cost savings for both the manufacturer of cast aluminum components and the end-user.
