A5052 is the Japanese JISH4000-1988 standard grade, which belongs to the industrial rust prevention aluminum alloy. It corresponds to the US standard 5052 aluminum alloy, the national standard 5A02 aluminum alloy, and the old grade is LF2 aluminum alloy. Now let's answer what material A5052 is made of.
A5052 aluminum belongs to the more commonly used alloy aluminum, the main element is magnesium, and the magnesium content is between 3-5%. Can also be called aluminum magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. In the same volume of aluminum magnesium alloy weight is lower than other series. It is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, which belongs to hot rolled aluminum, so it can do oxidation deep processing. In Japan imported aluminum alloy 5××× series aluminum is one of the more mature aluminum series.
Compared with the new standard grade of 5A02 aluminum alloy in China, A5052 aluminum alloy is Al-Mg anti-rust aluminum. Compared with 3A21, A5052 has higher strength, especially higher fatigue strength. High plasticity and corrosion resistance, similar to 3A21 in this respect; Heat treatment can not be strengthened, resistance welding and atomic hydrogen welding have good weldability, and argon arc welding has a tendency to form crystalline cracks; The alloy has good machinability under cold work hardening and semi-cold work hardening, poor machinability under annealing, and can be polished.
A5052 aluminum alloy is Al-Mg anti-rust aluminum alloy and cannot be strengthened by heat treatment. The alloy has a lower magnesium content, its plasticity is higher, and the strength is lower, but the strength is higher than 3A21 aluminum alloy. Cold deformation can increase its strength and decrease its plasticity. The alloy has good corrosion resistance and is suitable for use in Marine environment. The alloy has good weldability. Its machinability is poor in annealing state, and the machinability can be improved in semi-cold cherry blossom state.
A5052 aluminum alloy is suitable for welding structures and containers with high process plastic requirements and good corrosion resistance, such as tubes, gasoline and lubricating oil, nails, flanges, and light load parts, ships, vehicles interior decoration, etc., pickles are used as plans or welding rods.
