OEM/ODM, Design Service Offered
5A02 aluminum sheet belongs to 5 series Al-Mg antirust aluminum, with good corrosion resistance. Beside, the fatigue strength of 5A02 aluminum alloy is outstanding, which is higher than that of 3A21 alloy. In terms of plasticity, it is similar to 3A21 alloy, all has good formability. Similarly, 5A02 aluminum is a non-heat treated alloy, strengthened by cold working. Among them, under the condition of cold work hardening and semi-cold work hardening, the machinability of 5A02 aluminum alloy is good. Under the condition of annealing, the machinability is poor. So, the 5A02 aluminum sheet can be well applied to the manufacture of flange, oil tank, GIS high voltage switch shell, rivet or electrode, etc.
1. Weldability. 5A02 aluminum sheet has good weldability during resistance welding and atomic hydrogen welding. During argon arc welding, there is a tendency to form crystal cracks.
2. Plastic. The 5A02 aluminum alloy is also capable of turning, milling, boring, planing and other mechanical processing at the maximum speed of most machine tools.
3. Physical Properties. 5A02 aluminum sheet tensile strength σb (MPa)≤147, elongation δ10 (%)≥14.
4. Other Features. In addition, 5A02 aluminum alloy can be polished and so on.
5A02 Aluminum Sheet for Flanges
A flange is actually a connecting part that is bolted and closed around two surfaces. For example, connecting parts between pipes and pipes, or equipment import and export, are used in pairs. 5A02 aluminum sheet is used for flanges manufactured with good workability, formability, weldability and high fatigue resistance, so it's good to meet diversified demands in the shape of the flange, better appling to various kinds of complex structure of joint.
In addition, 5A02 aluminum sheet can also be well applied to the tank, GIS high voltage switch shell, rivet, welding rod, ship/traffic vehicle sheet metal parts manufacturing, etc.
