The classification of the aluminum alloy
A series: 1000 series aluminum alloy represents 1050, 1060, 1100 series. 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. Circulate on the market at present most of the 1050 and 1060 series. 1000 series aluminum plate according to the last two digits to determine the range of low aluminium content, such as series 1050, the last two digits for 50, according to the international brand naming principles, aluminum content must be more than 99.5% of qualified products. Aluminium alloy technology in China standard (gB/T3880-2006) is clearly stipulated in 1050 reached 99.5% aluminum content. The same 1060 series aluminum plate aluminum content must be above 99.6%.
Two series: 2000 series of aluminum alloy 2024, 2 a16 (LY16), 2 how a02 (LY6). 2000 series aluminum plate is characterized by high hardness, among them with copper originally belong to the highest levels, will be about 3-5%. 2000 series belong to the aviation aluminum bar, at present not often used in the conventional industry.
Three series: 3000 series aluminum alloy 3003, 3 a21. China 3000 series aluminum plate production process is relatively good. The 3000 series aluminum rod is composed of manganese element as the main component. Content is between 1.0 to 1.5, is a good series antirust function.
Four series: 4000 series aluminium stick represents for the 4 a01 4000 series of aluminum plate belongs to the high silicon content of the series. Usually between 4.5 6.0% silicon content. Belong to building materials, machinery parts, forging materials, welding materials; Low melting point, good corrosion resistance, the product description: has the characteristics of heat-resisting, wear-resisting
5 series, 5000 series aluminum alloy represents 5052, 5005, 5083, 5 a05 series. Belong to the more commonly used aluminum alloy 5000 series aluminum rod series, the main elements for magnesium, magnesium content between 3-5%. And could be called aluminum magnesium alloys. Main characteristics as low density, high tensile strength, elongation rate is high, the fatigue strength is good, but do not do heat treatment to strengthen. Under the same area of 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 series, 6000 series aluminum alloy represents 6061 mainly contains two elements magnesium and silicon, so focus on the advantages of 4000 series and 5000 series, 6061 is a kind of cold treatment of aluminium forging products, applicable to against corrosion, oxidizing demanding applications. Good workability, easy to coating, good workability.
The seven departments: 7000 series of aluminum alloy 7075 main contains zinc. Also belong to aircraft series, is copper alloy, aluminum and magnesium zinc is heat treatable alloys, belongs to hard aluminum alloy, have good wear resistance. Have good weldability, but poor corrosion resistance.
Eight series, 8000 series aluminium alloy is relatively commonly used for the 8011 belong to other series, most of the application of aluminum foil, aluminum rod production is not too common.
Nine series: is spare 9000 series aluminum alloys.
