2A12 aluminum rod

High-strength duralumin, which can be strengthened by heat treatment, and can be welded

　　2A12 aluminum alloy belongs to Al-Cu-Mg series aluminum alloy. Main features and application range: This is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity in quenched and just quenched state. It has good spot welding and good welding. It is used for gas welding. Sometimes there is a tendency to form intergranular cracks. After quenching and cold work hardening, the machinability of the alloy is good, but the machinability after annealing is low: the corrosion resistance is not high, and the anodic oxidation treatment and painting method or the surface is coated with aluminum Layer to improve its corrosion resistance.

6082 aluminum rod

Excellent weldability, corrosion resistance, formability and machinability

　　6082 is a heat-strengthened alloy with good formability, weldability, machinability and corrosion resistance. It also has medium strength. It can still maintain good operability after annealing. It is mainly used for mechanical structures. , Including bars, plates, pipes and profiles, etc. This alloy has similar but not identical mechanical properties to 6061 alloy, and its -T6 state has higher mechanical properties. Alloy 6082 is a very common alloy product in Europe, and also has a high application in the United States. It is suitable for processing raw materials, seamless aluminum tubes, structural profiles and customized profiles. 6082 alloy generally has good processing characteristics and good anode reaction performance. The most commonly used anodic reaction methods include removal of impurities and dyeing, coating, etc.
Alloy 6082 combines excellent weldability, brazing properties, corrosion resistance, formability and machinability. The -0 and T4 states of alloy 6082 are suitable for bending and forming occasions, and the -T5 and -T6 states are suitable for the requirements of good machinability. Some specific processing requires the use of chip separators or other special processes to help separate the chips; 6082 Alloys usually have good processing characteristics and good anode reaction performance;
