Knowledge Of Grade 3003 Aluminum Alloy

Standards of 3003 Aluminum manufacturing and its heat treatment process

     Aluminum sheet manufacturer standard and heat treatment process.Aluminum plate 3003 is a commonly used product in the series of aluminum and manganese alloys.Due to the manganese alloy element, the 3003 aluminum plate has excellent anti-rust properties, also known as anti-rust aluminum plate.

Characteristics Of Aluminum sheet 3003

     3003 for AL-Mn alloy, is one of the most widely used antirust aluminum, this kind of the strength of the alloy is not high, slightly higher than that of industrial pure aluminum), can’t heat treatment to strengthen, the cold working method is adopted to improve its mechanical properties: in annealing state has high plasticity, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low, good corrosion resistance, good weldability, cutting performance is bad.The utility model is mainly used for demanding high plasticity and good weldability, low-load parts working in liquid or gas medium, such as oil tank, gasoline or lubricating pipe, various liquid containers and other small load parts made with deep drawing: wire is used to make rivets.

Aluminum sheet heat treatment process

    1)Full annealing: heating to 390 ~ 430 ℃;With different effective thickness of the material, the insulation time is 30-120min.At 30 ~ 50 ℃ / h speed with furnace cooling to 300 ℃, the air cold again.

    2)Rapid annealing: heating to 350 ~ 350 ℃.With different effective thickness of the material, the insulation time is 30-120min.Air or water cooling.

    3)Quenching and aging: 500 ~ 510 ℃, quenching air cooling;Artificial aging 95 ~ 105 ℃, 3 h, air cooling;Natural aging room temperature 120h

    Aluminum plates are commonly used for welding parts for ships, ships, vehicles, automobile and aircraft plates, pressure vessels requiring strict fire protection, cooling units, TV towers, drilling equipment, transportation equipment, missile components, armor, etc.
