3000 Series Of Al-mn Alloy
Jan 07, 2018

3000 Series of al-mn alloy, also known as rust-proof aluminum.

Representative aluminum alloy 3003,3004, 3A21-based


① Mn alloy elements as the main aluminum alloy, not heat treatment to strengthen.

② good plasticity, good welding performance, corrosion resistance slightly stronger than 1 series, is a medium strength aluminum alloy.

③ annealing temperature: low temperature annealing 260-360 ℃, high temperature annealing 370-490 ℃.

Uses: Mainly used for the intensity of a series of slightly higher than the intensity of work, pressure tanks, storage tanks, insulation materials, mechanical parts, fuel tanks and other aircraft. Conventional applications in air conditioners, refrigerators, car bottom and other humid environment, the price is higher than the 1 × × × series, is a more commonly used alloy series.

3003 is used to process parts that require good formability, high corrosion resistance, good solderability, or require both these properties and work harder than 1XXX alloys. Various pressure vessels and pipes

3004 aluminum cans can body, requiring more strength than the 3003 alloy parts

3105 Room partition, baffle board, mobile board, gutters and downpipes, sheet metal forming parts, caps, corks, etc.

3A21 aircraft fuel tank, oil conduit, rivets wire, etc .; industrial equipment such as building materials and food etc
