What Are Heat Treatable Aluminum Alloys

Aviation aluminum alloy is one of the most important structural materials in aircraft body structure. Currently, three major aviation aluminum alloy systems have been developed internationally: high-strength and high-toughness aluminum alloys, high-strength/high-ratio die aluminum alloys, and scandium-containing high-performance aluminum alloys. Research on new-generation high-performance alloys, high-flexibility preparation and processing, and data-driven high-efficiency alloy design is a major development trend.

Aircraft aluminum alloys mainly include high-strength/ultra-high-strength and high-toughness Al-Zn-Mg-Cu series (7xxx series), medium-high strength and damage-resistant Al-Cu series (2xxx series), and medium-strength weldable Al-Mg-Si series (6xxx series), as well as high-strength and high-ratio lightweight Al-Li alloys and a small amount of other alloys. Different forms are available: thick plates, thin plates, forgings, extruded materials, castings, etc.

The aluminum alloys used in large aircraft structures in various countries around the world today are mainly 7075, 7475, 7050, 7150, 7055, 7085, etc., and 2024, 2224, 2324, 2424, 2524, etc. They are mainly used in aircraft fuselage components, engine nacelles, seats, control systems, etc.

7075 aluminum alloy is a kind of Al-Zn-Mg-Cu series aluminum alloy with high strength and is better than mild steel. The hot sale 7075 t6 aluminium is its common temper. It has ordinary corrosion resistance and good mechanical properties. Fine grains enable better deep drilling performance and better wear resistance. Zn is the main alloy element in 7075. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with significant strengthening effect, making the heat treatment effect of this alloy far better than that of Al-Zn binary alloy.

2024 aluminum is an Al-Cu-Mg aluminum alloy that can be strengthened through heat treatment and has moderate plasticity in the quenched and freshly quenched states. The classic 2024 aluminum alloy has also developed a series of improved grades by reducing the Fe and Si impurity content and improving the alloy purity and metallurgical quality, such as 2124, 2224, 2324, etc.

2024-T3 aluminum plate has high strength and also has excellent fatigue resistance. Welding is generally not recommended. Its typical uses are fuselage and wing skins, roofs, aircraft structures,etc. Its ultimate strength is 62,000 PSI and shear strength is 40,000 PSI. Haomei Aluminum is one of the 7075 and 2024 t3 aluminum suppliers in China. Welcome to leave message below to inquire what you need.
