What are the characteristics of 6063 aluminum tube?
1. Strengthened by heat treatment, high impact toughness, insensitive to defects.
2. With excellent thermoplasticity, it can be extruded into complex thin-walled hollow profiles at high speed or forged into forgings with complex structures. Wide quenching temperature range and low quenching sensitivity. After extrusion, forging, demoulding, as long as the temperature is higher than the quenching temperature. That is, it can be quenched by spraying water or piercing water. Thin-walled parts (6<3mm) can also be air quenched.
3. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Among the heat treatable aluminum alloys, Al-Mg-Si alloy is the only one without stress corrosion cracking.
4. The surface is very smooth after processing, easy to anodize and color. The disadvantage is that if it is parked at room temperature for a period of time after quenching and then aged, it will damage the strength (parking effect).
What is the relationship between 6063 aluminum tube T5 and T6?
6063 Aluminum Tube is a hollow metal tubular material extruded from aluminum alloy along its entire longitudinal length. Both T5 and T6 of 6063 aluminum tubes are heat treated. 6063 aluminum tube T5 is the aluminum profile extruded from the extruder, then cooled rapidly by air cooling to meet the hardness requirements of the aluminum tube.
6063 aluminum tube T6 is an aluminum profile extruded from an extrusion machine. The aluminum profile is cooled instantly by water cooling to make the aluminum profile meet higher hardness requirements.
6063 aluminum tube T5 is generally air-cooled when quenched in the profile factory, and 6063 aluminum tube T6 is generally water-cooled when quenched in the profile factory. Both have the same modulus of elasticity. Generally, the T5 state is used. If the rod deflection passes but the tensile strength is slightly poor, the T6 state can be adopted. The strength of T6 is better than T5, but T6 is generally more expensive than T5.
