Material-04 Aluminum 2A12

名称：铝2A12

制造工艺：数控加工

应用

2A12铝合金是一种高强度硬铝，可通过热处理强化； 2A12铝合金具有良好的点焊性，使用气焊和氩弧焊时容易形成晶间裂纹； 2A12铝合金冷加工硬化后可切割 性能良好。 耐腐蚀性不高。 常采用阳极氧化处理和涂漆方法或表面镀铝以提高耐腐蚀性。 用途主要用于制造飞机上150℃以下的各种高负荷零部件（但不包括冲压件和锻件），如骨架件、蒙皮、舱壁、加强筋、翼梁、铆钉等工作部件。

Applications

2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be strengthened by heat treatment; 2A12 aluminum alloy has good spot weldability, and tends to form intergranular cracks when using gas welding and argon arc welding; 2A12 aluminum alloy can be cut after cold work hardening Performance is good. The corrosion resistance is not high. Anodizing treatment and painting methods are often used or the surface is coated with aluminum to improve the corrosion resistance. Uses are mainly used to make various high-load parts and components (but not including stamping parts and forgings) such as skeleton parts, skins, bulkheads, ribs, spar, rivets and other working parts below 150 ℃ on aircraft.‍
