1. What is aluminum alloy 2024 (AlCu4MgSi1)
2024 (AlCu4MgSi1) Aluminum alloy is an aluminum alloy with copper as the main alloy element. It is called hard aluminum. It has high strength and good cutting performance, but poor corrosion resistance, but is usually coated with aluminum or Al- 1Zn for protection. For applications requiring a high strength-to-weight ratio and excellent fatigue resistance. It can only be welded by friction welding and has average machinability. In the old nomenclature, the 2XXX series alloys were known as duralumin and this alloy was known as 24ST. 2024 Typically extruded, also available in Alclad sheet and plate form.
The 2024 (AlCu4MgSi1) aluminum alloy has a density of 2.78 g/cm3 (0.1 lb/in3), a conductivity of 30% IACS, Young's modulus of 73 GPa (10.6 Msi) in all states, and a melting temperature of 500 °C ( 932°F). start. ).2024 aluminum alloy composition contains approximately 4.3-4.5% copper, 0.5-0.6% manganese, 1.3-1.5% magnesium, and less than 0.5% silicon, zinc, nickel, chromium, lead, and bismuth.
