Aluminum alloy 6061 and 6063 alloy are widely popular materials in the extrusion industry.
The composition and mechanical properties of each alloy are almost the same, with only slight differences in the added elements. Both contain magnesium to increase strength and silicon to reduce melting temperature; The price difference between the two is basically negligible.
6061 aluminum alloy has twice the iron content, and usually contains more copper, chromium and silicon than 6063. On average, the aluminum content of the latter can be up to 3.5% higher.
In order to strengthen their wider application, you can heat treat these two materials.
6061 aluminum alloy is an ideal choice for structural applications and construction projects that require high-strength profiles.
These products can have different material hardness grades according to different heat treatment processes. The Brinell hardness table is a standard measurement system for identifying the hardness of materials. The Brinell hardness value of 6061 aluminum alloy is usually 95, while that of 6063 is 73.
