What are the characteristics and performance of 6000 series aluminum products?

6063 belongs to the AI-Mg-si alloy, which is widely used, especially in the construction industry. It is the most promising alloy. Good corrosion resistance, excellent weldability, good cold workability, and medium strength. The main alloy elements are magnesium and silicon. It has excellent processability, excellent weldability, extrudability and electroplating, good corrosion resistance, toughness, easy polishing, color film, and excellent anodizing effect. It is a typical extrusion alloy.

6063 aluminum alloy profiles are widely used in building profiles, irrigation pipes, pipes, rods and profiles for vehicles, racks, furniture, elevators, fences, etc., due to their good plasticity, moderate heat treatment strength, good welding performance and gorgeous color of the surface after anodizing.

What are the advantages of 6000 series aluminum products?

A-Mg-si system high plasticity alloy with low alloying. It has many valuable features: 1. It is strengthened by heat treatment, with high impact toughness, and is insensitive to defects. 2. It has excellent thermoplasticity. It can be extruded into various shapes with complex structure, thin wall and hollow at high speed. It can be forged into forgings with complex structure. The quenching temperature range is wide, and the quenching sensitivity is low. After extrusion and forging demoulding, as long as the temperature is higher than the quenching temperature. It can be quenched by spraying water or penetrating water. Thin-walled parts (6<3mm) can also be air quenched. 3. The welding performance and corrosion resistance are excellent, and there is no tendency of stress corrosion cracking. Among the heat-treatable aluminum alloys, AI-Mg-Si alloy is the only alloy that has not found stress corrosion cracking. 4. The machined surface is very smooth and easy to anodize and stain.

What are the disadvantages of 000 series aluminum products?

Its disadvantage is that if it is aged at room temperature for a period of time after quenching, it will adversely affect the strength

What are the characteristics of 6061 aluminum?

General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good usability, and strong corrosion resistance.

What are the uses of 6061 aluminum?

Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, ship parts and hardware, electronic parts and connectors, decorative or various hardware, chain head, magnetic head, brake piston, hydraulic piston, electrical parts, valves and valve parts.

What are the grades of 6000 series aluminum alloy?
