2024 aluminum flat bar is a high-strength duralumin, which belongs to the Al-Cu-Mg series of aluminum alloys. 2024 aluminum can be strengthened by heat treatment. In the quenched and just quenched state, 2024 aluminum has moderate plasticity. 2024 aluminum has good spot welds but is not very corrosion resistant.2024 aluminum flat bar is mainly used to make various high-load parts and components (but not including stamping parts and forgings). Such as skeleton parts, skins, bulkheads, wing ribs, spars, rivets and other working parts below 150°C on the aircraft.
5052 aluminum flat bar is a widely used Al-Mg alloy. The main alloying element of 5052 aluminum is magnesium, which has good processability, corrosion resistance, weldability and medium strength.5052 aluminum flat bar is suitable for low load parts working in liquid or gaseous medium. Such as fuel tank oil pipes, sheet metal parts of transportation vehicles and ships, instruments, street lamp brackets and rivets, hardware products, electrical shells, etc.
6061 aluminum flat bar is a heat-treatable alloy that can be strengthened. 6061 aluminum has good formability, weldability and machinability. At the same time, it has many characteristics such as medium strength, good corrosion resistance, high toughness, easy coloring film, and excellent oxidation effect.6061 aluminum flat bar is widely used in various industrial structural parts that require certain strength and high corrosion resistance. Such as manufacturing trucks, tower buildings, ships, trams, railway vehicles, automated machinery parts, precision machining, mold manufacturing, electronics and precision instruments, etc.
6063 aluminum flat bar is a heat treatable strengthening alloy with medium strength in the AL-Mg-Si series alloy. 6063 aluminum flat bar is widely used in the frame of architectural aluminum doors, windows and curtain walls.
7075 aluminum flat bar is a cold-treated forging alloy with high strength, which is far better than mild steel. 7075 aluminum has compact structure, strong corrosion resistance, good mechanical properties and anodic reaction.7075 aluminum flat bar is mainly used in aerospace, mold processing, mechanical equipment, fixtures. Especially for the manufacture of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
