2A11 aluminum sheet radiator with a military aluminum is a high strength duralumin with a very wide range of applications. The most common is in the military with aluminum are Al-Cu-Mg alloys, industrial radiators with 2A11 aluminum sheet heat treatment can be enhanced in quenching and just quenched plastic medium, spot welding good, quenching and cold work hardenability after cutting performance is good, often using anodizing and painting methods or surface with aluminum coating to improve its anti-corrosion ability, 2A11 aluminum alloy is common Military use of aluminum.
Industrial radiator can be widely used in light industry, construction, machinery, metallurgy and other industries hot air heating, air conditioning, cooling, condensation, dehumidification, drying and so on. 2A11 aluminum sheet commonly used in industrial radiators, because of its heat dissipation.
2A11 aluminum alloy belongs to the AL-CU-MG series aluminum alloy, the main characteristics and application range: This is a high-strength hard aluminum, can be enhanced by heat treatment, commonly referred to as a standard hard aluminum, with moderate intensity, at annealing, quenching and thermal state just plasticity is still good, can heat strengthened, used in the quenched and naturally aged condition, the point Welding is good, there is tendency to crack When welding and welding; aging can be cut in the quenched state is still good, bad in the annealed condition.
