Various applications have different aluminum alloy materials requirements
- 2017-10-09 10:16 -
Aluminum alloy with low density, high strength, good plasticity, can be processed into a variety of profiles, is widely used in life, military, science and technology, aluminum alloy grades categories, specifications are countless, how to buy aluminum Choose the right aluminum alloy sheet, need to start from their own product demand, select the performance for their own products, so that a reasonable selection, to ensure the performance of the premise of reasonable cost control. From the hardness, strength, corrosion resistance, processing, welding and other considerations.
Many customers are very concerned about the hardness of the purchase of aluminum, hardness, first with the aluminum alloy chemical composition has a direct relationship. In fact, different states also affect the larger. From the highest hardness can be achieved: 7 series, 2 series, 6 series, 5 series, 3 series, 1 series in turn lower.
Strength is an important factor that must be taken into account in the design of the product. Especially when the aluminum alloy is used as a structural member, the appropriate alloy should be selected according to the pressure. Pure aluminum strength is the lowest, while the 2 series and 7 series heat treatment alloy strength is the highest. Hardness and strength have a certain positive correlation.
Corrosion resistance:
Corrosion resistance, including chemical resistance, resistance to electrochemical corrosion, stress corrosion resistance and other properties. In general: 1 Department of pure aluminum corrosion resistance is best, 5 series of good performance, followed by 3 series and 6 series, 2 series and 7 series is poor. The principle of corrosion resistance should be determined according to its use. High-strength alloys used in corrosive environments, must use a variety of anti-corrosion composite materials.
Processing performance:
Processing performance includes line performance in cutting performance. Because the formability and the state, in the choice of aluminum alloy grades, the need to consider the strength range of various states, usually high strength materials is not easy to shape. If the aluminum is to be bent, stretched, deep punching and other forming processing, the final annealing state of the best shape. Conversely, the heat treatment state material has the worst formability. Aluminum alloy cutting performance and alloy composition has a great relationship, usually high strength aluminum alloy machinability is better, on the contrary, low-intensity machinability is poor. For the mold, mechanical parts and other products need to be machined, the machinability of aluminum is an important consideration.
Welding performance:
Most of the aluminum alloy welding is no problem, especially part of the 5 series of aluminum alloy, is designed for welding considerations. In contrast, some 2 and 7 series of aluminum alloy is difficult to weld.
