6063-T4是什么钢种？

是含镁和硅的铝合金

6063 is an aluminum alloy, with magnesium and silicon as the alloying elements. It has generally good mechanical properties and is heat treatable and weldable.

6063 is particularly used for producing structural shapes using extrusion, and typically has very smooth surfaces.

6063-T4

T4 temper 6063 has an ultimate tensile strength of at least 19,000 psi in thicknesses up to 0.5 inch, and 18,000 psi from 0.5 to 1.0 inch thick, and yield strength of at least 10,000 psi up to 0.5 inch and 9,000 psi from 0.5 to 1.0 inch. It has elongation of 14%

用途：

6063 is used for architectural fabrication, window and door frames, pipe and tubing, electrical conductors, and aluminum furniture. [1]

[edit] Welding

6063 is highly weldable, using Tungsten inert gas welding. Typically, after welding, the properties near the weld are those of 6063-0, a loss of strength of up to 30%. The material can be re-heat-tr
