A series of pure aluminum alloy: of all the series, 1000 series belongs to a series of aluminum content in the most. Purity can reach more than 99.00%. Because do not contain other technical elements, so the production process is single, the price is relatively cheap, is currently the most commonly used in conventional industry a series.

Two copper aluminum alloy: a typical hard aluminum alloy, its composition is reasonable, comprehensive performance is better. Many countries are the alloy production, is the largest in the dural dosage. The characteristics of the alloy are: high strength, a certain heat resistance. Among them with copper originally belong to the highest levels, will be about 3-5%.

Belong to the more commonly used 5 series aluminium magnesium alloy, alloy aluminum plate series, the main elements for magnesium, magnesium content between 3-5%. Main characteristics as low density, high tensile strength, elongation rate is high, good fatigue strength, in the same area under the weight of the aluminum magnesium alloy is lower than other series. Are widely applied in the conventional industry. 5000 series aluminium plate in our country belongs to the series of aluminum plate is relatively mature.

Six magnesium aluminum silicon alloy: is a kind of cold treatment of aluminium forging products, applicable to against corrosion, oxidation demanding applications. Good workability, easy to coating, good workability. Containing magnesium and silicon two main elements.

Seven is copper alloy, aluminum zinc magnesium is heat treatable alloys, belongs to hard aluminum alloy, have good wear resistance. Have good weldability, also belong to the aviation series, to contain zinc. After solid solution treatment, the plasticity is good, heat treatment reinforcement effect is very good, and have a very good low temperature strength, is praised as the most excellent products in aluminum alloy, high intensity, far more than mild steel. The alloy has good mechanical properties and the anode reaction, is a typical air with aluminum.

Aluminum: based on aluminum base alloy. Main alloying elements are copper, silicon, magnesium, zinc, manganese, secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.

Aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used on industry, usage is second only to the steel.
