The aluminum alloy products are divided into seven kinds of aluminum alloys, such as LF, LY, LD, LC, LB, LT and brazing (LQ). Aluminum alloy products are divided into:
The 1 system is 1000 aluminum, which is more than 99% of aluminum and is called pure aluminum. The price is lower than that of the 3 series aluminum, which is about 2000 yuan / ton, and the corrosion resistance is poor. The 3 line 3000 aluminum alloy is manganese aluminum alloy, which has better performance and higher price. The 5 line 5000 aluminum alloy is magnesium aluminum alloy, which has the best performance and the price is higher than that of the 3 aluminum alloy. (3 and 5 series aluminum is commonly called antirust aluminum, widely used in building exterior wall, such as aluminum curtain wall, plastic aluminum plate, etc.) 6 system 6000 aluminum alloy is magnesium silicon aluminum alloy, commonly known as forged aluminum; the price is 3000 yuan / ton.1 of aluminum lower than 3000 aluminum. The aluminum section is 6 series aluminum, it must be formed by anodizing the protective film - the thickness and firmness of the oxide film is the wear resistance of aluminum. The key to corrosion resistance. 2) 6 series aluminum is not suitable for making rainwater pipes, and the 6 aluminum is not rust proof unless the inner wall of the tube is made anticorrosive or paint treated.
