1. What is aluminum alloy 2024/A92024
Aluminum alloy 2024/A92024 has copper as its primary alloying constituent. It is utilized in applications where a high strength-to-weight ratio and exceptional fatigue resistance are necessary. It has moderate machinability and can only be joined by friction welding. They frequently have aluminum or Al-1Zn coating to prevent corrosion, despite the fact that doing so may lower their fatigue strength. The 24ST alloy belonged to the 2XXX class of alloys, which were referred to as duralumin in the previous designation system. In addition to being available in foil and plate form, 2024 is generally extruded. It is not frequently faked.
