2024 2A12 aluminum hexagonal hollow tube is extruded into 2024, 2A12 aluminum alloy into a metal tubular material hollow along its longitudinal length. LY12 is a kind of high-strength hard aluminum which can be heat-treated and strengthened. It has medium plasticity in the state of annealing and quenching. The spot welding property is good. There is a tendency to form intergranular cracks when using gas welding and argon arc welding. The alloy is quenched and cooled. It has the machinability after hardening, low machinability after annealing, and low corrosion resistance. It is often anodized and painted or coated with aluminum to improve its corrosion resistance.
2024 2A12 aluminum hexagonal hollow tube characteristics and scope of application:
2024 2A12 aluminum hexagonal hollow tube is an Al-Mg-Si alloy, medium strength, plastic and corrosion resistant. In particular, it has a tendency to be free from stress corrosion cracking, has excellent weldability, good corrosion resistance and cold workability, and is a promising alloy with a wide range of applications. It can be anodized and colored, or it can be painted on the enamel, suitable for building decoration materials. It contains a small amount of Cu, so the strength is higher than 6063, but the quenching sensitivity is also higher than 6063. After quenching, wind quenching cannot be achieved, and re-solution treatment and quenching aging are required to obtain higher strength.
2024 2A12 aluminum hexagonal hollow tube performance introduction:
1. Densification: The unique grain refining process guarantees that all aerospace product series are inspected by ultrasonic flaw detection process for aerospace aluminum alloy products, without sand holes, cracks, bubbles and impurities.
2. Internal stress (artificial aging): Perfect pre-stretching eliminates internal stress processing, completely eliminates internal stress, and the product does not warp, crack and deform during processing and stress.
3. Tolerance Accuracy: All products comply with American Society for Testing and Materials (ASTM) and Aerospace Materials (AMS). Most products have tolerances that exceed ASTM 1/2 tolerance. Some product tolerances can even exceed ASTM 1/. 4 standard tolerance accuracy.
