Aluminium and Aluminium Alloy Plate with Non-Heat Treatable Strengthening
Aluminum and aluminum alloy plate with non-heat treatable strengthening, referred to as GBn 168-82, is a kind of new non-heat treatable strengthening aluminum alloy. It has a higher strength than common aluminum alloy, 1/2-1/3 tensile strength of aluminum alloy, but poor plasticity, poor welding performance and poor workability.
The maximum working temperature of GBn168-82 aluminum alloy plate is 160 degrees Celsius. When the temperature is higher than 160 degrees Celsius, the alloy structure can be destroyed, resulting in lower wear resistance and strength. The hardness of GBn168-82 aluminum alloy plate is dependant on tempering, but the plate does not require heat-treatment for strengthening so the plate may contain re-crystallized grains.
GBn 168-82 aluminum alloy plate contains various alloy elements such as manganese, zinc, magnesium, copper, etc., and is added with appropriate stabilizers such as Sr, Cu, and Mg, so that the casting structure becomes fine and uniform spheroidization, and hydrogen solid solution is scattered in the alloy structure, forming a reinforcing effect against high temperature creep.
The chemical composition of GBn 168-82 aluminum alloy plate is mainly composed of ferromagnetic metals such as aluminum, iron, manganese, silicon, and a small amount of zinc, magnesium, copper, etc. The main impurities are chromium and titanium with a maximum content of 0.1%. This alloy has excellent oxidation resistance, corrosion resistance and wear resistance.
The main application of GBn 168-82 aluminum alloy plate is the production of high strength and wear-resistant aluminum alloy parts, such as aircraft, automobile and ship molds, machinery manufacturing and other machinery and equipment, and other load-bearing parts.
GBn 168-82 aluminum alloy plate is also suitable for the chemical treatment of anodizing, acid pickling, electroplating and chemical coloring. Compared with other common aluminum alloys, GB n 168-82 aluminum alloy plate has a higher one-time forming accuracy, and can be rolled and completed, which greatly reduces production costs and improves production efficiency.
In summary, GBn 168-82 aluminum alloy plate is a kind of new non-heat treatable strengthening alloy. Its superior mechanical properties, electrical properties and chemical properties make it ideal for manufacturing machinery parts and motor parts thatrequire high strength and wear-resistance. The excellent oxidation resistance and corrosion-resistance of GBn 168-82 aluminum alloy plate enables it to be used in a variety of difficult environments.
