The 6063 cold drawn aluminum capillary tube is a low alloyed A-mg-based high plasticity alloy tube.It has many valuable features: 1 heat treatment strengthening, high impact toughness, can not be sensitive to lack of. 2 It has excellent thermoplasticity, can be extruded at high speed into various profiles with complex thin-walled hollow structure or forged forgings with complex structure, wide quenching temperature range, low quenching sensitivity, high temperature after extrusion and forging demoulding At quenching temperature. That is, it can be quenched by spraying water or water. 6063 aluminum thin-walled parts (6<3mm) can also be quenched. 3, excellent welding performance and corrosion resistance, no stress corrosion cracking tendency, in the heat-treated reinforced aluminum alloy, -mg-si alloy is rarely found in stress corrosion cracking phenomenon. The surface of the 4.6063 colddrawn aluminum capillary tube’s surface is very smooth and easy to anodize and color. The disadvantage is that if it is aged at room temperature for a period of time after quenching, it will have an adverse effect on the strength (parking effect).
