According to the metal elements contained in aluminum rectangular bars, aluminum rectangular bars can be roughly divided into 8 categories, that is, they can be divided into 9 series.
1, 1000 series aluminum rectangular bars represent the 1050 rectangular bars, 1060 rectangular bars, and 1100 series. In all series, the 1000 series belong to a series with the largest amount of aluminum. The purity can reach more than 99%. Because it does not contain it
Because of its technical elements, the production process is relatively simple and the price is relatively cheap, which is the most commonly used series in the conventional industry at present. Most of the current circulation in the market is 1050 rectangular bars And the 1060 series rectangular bars. The 1000 series of aluminum panels determine the minimum aluminum content of the series according to the last two Arabia figures, such as the 1050 series rectangular bars, the last two Arabia figures, 50.According to the international brand naming principle, the aluminum content must reach 99.5%, and the qualified product is above. China's aluminum alloy technical standard (gB/T3880-2006) also specified 1050 rectangular bars content.To achieve the same 99.5%., the aluminum content of the 1060 series aluminum plates must reach more than 99.6%.
2,2000 series aluminum rectangular bars represent 2011 rectangular bars and 2024 rectangular bars.
The 2000 series aluminum plate is characterized by high hardness, of which copper is the highest content, about 3-5%. The 2000 series aluminum rectangular bars belong to aviation aluminum and are not commonly used in conventional industries.
Application.
The 2024 rectangular bars is a typical hard aluminum alloy in Al Cu mg system. It is a heat treatable alloy, with high strength, easy processing, easy turning and corrosion resistance. 2024 rectangular bars
After heat treatment (T3, T4, T351), the mechanical properties are greatly improved, and the T3 state parameters are as follows: tensile strength 470MPa, 0.2% yield strength 325MPa, elongation rate: 10%, fatigue.
The strength of the strain is 105MPa, and the hardness is 120HB. 2024 the main uses of aluminum rectangular bars are aircraft structure, rivets, truck wheels, propeller components and other structural parts.
3, 3000
The series of aluminum rectangular bars represent 3003 rectangular bars and 3A21 rectangular bars. The production technology of 3000 series of aluminum plates in China is excellent. The 3000 series of aluminum rectangular bars are composed of manganese elements. The content is between 1.0-1.5,
It is a series of good antirust functions.
