Al-Mg Alloy Aluminum Plate 5052

Aluminum - magnesium alloys also contain small amounts of manganese, chromium, beryllium, titanium, etc.
Except for a small amount of solid solution, most of the manganese in the alloy forms MnAl6.

The effect of chromium in 5052 aluminum plate is similar to that of manganese, which can improve the stress corrosion cracking resistance, improve the strength of base metal and weld, and reduce the welding crack tendency, but the content of chromium in 5052 aluminum plate is generally less than 0.35%.

GB/T3880-2006 characteristics and scope of application: ① 5052 belongs to the Al-Mg alloy, the use of a wide range, especially the construction industry cannot do without this alloy, is the most promising alloy.

Good corrosion resistance, good weldability, good cold working property, and has medium strength.
The main alloy element of 5052 is magnesium, which has good forming processing performance, corrosion resistance, weldability and medium strength. It is used in the manufacture of aircraft fuel tanks, oil pipes, sheet metal parts of traffic vehicles and ships, instruments, street lamp supports and rivets, hardware products, electrical appliance shells and so on.

(2) Al-Mn alloy, is the most widely used a rust resistant aluminum, this alloy has high strength, especially with fatigue strength: high plasticity and corrosion resistance, can not be strengthened by heat treatment, in the semi-cold hardening of good plasticity, cold hardening of low plasticity, good corrosion resistance, good weldability, poor cutting performance, can be polished.
It is mainly used for demanding high plasticity and good weldability, low load parts working in liquid or gas medium, such as oil tank, gasoline or lubricating oil conduit, various liquid containers and other small load parts made by deep drawing: wire is used to do rivets.

hardness
Hardness: the tensile strength of 1060 aluminum plate is between 110 and 130, while the tensile strength of 5052 series is between 210 and 230, that is to say, the hardness of 5052 is 100% higher than that of 1060.
Elongation: the elongation of 1060 series is 5%, while the elongation of 5052 series is between 12-20%. It can also be thought that the elongation of 5052 series is about 200% higher than that of 1060 series.
Chemical properties: 1060 is pure aluminum plate, 5052 is alloy aluminum plate, 5052 is better corrosion resistance in special environment
