6063 Aluminium Extrusion Profile
AlMg0.7Si extrusion alloy, T5 / T6
6063 is the workhorse extrusion alloy: magnesium and silicon in balance give it good extrudability, a smooth anodised surface and adequate strength in T5 and T6. It is the material behind window and door systems, heat sinks, LED profiles, handrails and light structural sections. We supply standard sections and custom dies, mill finish, anodised or powder coated.
