Grades of aluminum alloys and their alloy composition

The aluminum alloy we usually say is generally aluminum magnesium silicon alloy, that is, 6 series aluminum alloy. This kind of aluminum alloy profile has a certain hardness, can meet the general load-bearing requirements, and corrosion resistance, the most widely used. But aluminum alloy is not only this category. Internationally, aluminum alloys are classified according to different components of aluminum alloys, that is, they are divided into different grades.

1 series of aluminum alloy is pure aluminum series, aluminum content of 99.9%, such as 1020, 1060, 1100, 1150, 1170, 1175, 1180, 1185, 1193, 1199, 1200, 1230, 1260, 1345, 1350, 1370, 1030, 1060, 1345, 1350, 1370...

2 series aluminum alloy is copper aluminum alloy, aluminum alloy with copper as the main alloying element, will also add magnesium, lead and bismuth to improve the cutting performance.2系铝合金有2A12,2011, 2014, 2017, 2021, 2024, 2034, 2117, 2124, 2218, 2219, 2224, 2319, 2324, 2519, 2618...

3 series aluminum alloy is an aluminum-manganese alloy, with manganese as the main alloying element. Can not be strengthened by heat treatment, good corrosion resistance, good welding performance, good plasticity, close to super aluminum alloy. The 3 series aluminum alloy grades are 3002, 3003, 3009, 3010, 3011, 3012, 3015, 3103, 3104, 3A12, 3A21, 3203, 3303...

4 series aluminum alloy is an aluminum-silicon alloy, with silicon as the main alloying element. Some can be strengthened by heat treatment, and this kind of aluminum alloy is not commonly used. The main brands are 4004, 4032, 4047, 4104...

5 series aluminum alloy, is aluminum magnesium alloy, magnesium is the main alloying element. This kind of aluminum alloy has good corrosion resistance, good welding performance and good fatigue strength. However, it can not be strengthened by heat treatment, and the strength can only be improved by cold processing. The brands are 5005, 5010, 5013, 5014, 5016, 5040, 5042, 5043, 5049, 5050, 5051, 5052, 5056, 5082, 5083, 5086, 5150, 5151, 5154, 5182, 5183, 5205, 5250, 5251, 5252, 5254, 5280, 5283, 5351, 5356, 5357, 5451, 5454, 5456, 5457, 5552, 5652, 5657, 5754, 5854...

6 series aluminum alloy, the most widely used aluminum alloy. Magnesium and silicon are the main alloying elements. Its strength is medium, corrosion resistance is good, welding performance is good, easy extrusion molding and oxidation coloring. Therefore, most aluminum alloy profiles are 6 series aluminum alloys. There are 6008, 6011, 6012, 6015, 6053, 6060, 6061, 6063,6066, 6070, 6082, 6101, 6103, 6105, 6110, 6111, 6151, 6162, 6181, 6205, 6253, 6261, 6262, 6351, 6463, 6763, 6863, 6951...

7 series aluminum alloy, zinc as the main alloying element, but at the same time will also add a small amount of copper and magnesium. Superhard aluminum alloy is a 7 series, containing zinc, lead, magnesium, copper, hardness close to steel. 7 series aluminum alloy profile extrusion cost is relatively high, good welding performance. Commonly used in aerospace.) Seven series aluminum alloy grades are 7001, 7003, 7004, 7005, 7008, 7009, 7010, 7011, 7012, 7013, 7014, 7015, 7017, 7019, 7020, 7021, 7022, 7023,7024、7026、7027、7028、7029、7030、7039、7046、7049、7050、7051、7060、7072、7075、7075- t651、7076, 7079,7108, 7109,7116,7146, 7149,7150,7175,7179,7229,7278,7472,7475...7005和7075 is the highest level of the 7 series.
