How many types of aluminum alloys

1. How many classifications are there for aluminum alloys?  Answer: One series: 1000 series aluminum alloy represents 1050, 1060, 1100 series.  The 1000 series is the most aluminum-containing series among all series.  The purity can reach more than 99.00%.  Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in conventional industry.  Most of the current circulation in the market are 1050 and 1060 series.  The 1000 series aluminum plate determines the minimum aluminum content of this series according to the last two Arabic numbers. For example, the last two Arabic numbers of the 1050 series is 50. According to the international brand naming principle, the aluminum content must be above 99.5% to be qualified products.  China's aluminum alloy technology standard (GB / T3880-2006) also clearly stipulates that the aluminum content of 1050 reaches 99.5%. The same reason for the aluminum content of 1060 series aluminum plates must reach 99.6% or more.

Second series: 2000 series aluminum alloys represent 2024, 2A16 (LY16), 2A02 (LY6).  The 2000 series aluminum plate is characterized by high hardness, of which the original copper content is the highest, about 3-5%.  2000 series aluminum rods belong to aviation aluminum and are not often used in conventional industries.  Three series: 3000 series aluminum alloys are mainly 3003 and 3A21.  China's 3000 series aluminum plate production process is excellent.  The 3000 series aluminum rods are made of manganese.  The content is between 1.0-1.5, which is a series with better anti-rust function.  Four series: 4000 series aluminum rods represent 4A01 4000 series aluminum plates belong to the series with higher silicon content.  The silicon content is usually between 4.5-6.0%.  It belongs to building materials, forging materials for mechanical parts, welding materials; low melting point, good corrosion resistance, product description: heat resistance and wear resistance.  Five series: 5000 series aluminum alloys represent 5052, 5005, 5083, and 5A05 series.  5000 series aluminum rods belong to the more commonly used alloy aluminum plate series. The main element is magnesium, and the magnesium content is between 3-5%.  Also called aluminum-magnesium alloy.  The main features are low density, high tensile strength, high elongation, and good fatigue strength, but it cannot be strengthened by heat treatment.  Under the same area, the weight of aluminum-magnesium alloy is lower than other series. It is also widely used in conventional industry.  5000 series aluminum plate is one of the more mature aluminum plate series in China.  Six series: 6000 series aluminum alloy represents 6061 mainly contains two elements of magnesium and silicon, so the advantages of 4000 series and 5000 series are concentrated. 6061 is a cold-treated aluminum forged product, which is suitable for applications with high requirements for corrosion resistance and oxidation.  Good workability, easy coating and good processability.  Seven series: 7000 series aluminum alloy represents 7075 mainly contains zinc element.  It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and belongs to a super-hard aluminum alloy. It has good abrasion resistance. It also has good weldability, but poor corrosion resistance.  Eight series: 8000 series aluminum alloy is more commonly used as 8011 belongs to other series, most of the applications are aluminum foil, not very common in the production of aluminum rods.  Nine series: 9000 series aluminum alloy is a spare alloy.
