Medium-Strength Structural
6005
The sweet spot between strength and extrudability, nearly matching 6061 with better surface finish.
270–310 MPa UTS
225–260 MPa Yield Strength
8–11% Elongation
6005 offers properties between 6063 and 6061, often used interchangeably with either. Less quench-sensitive than 6061, it allows more complex shape production. In T5 temper, it matches 6061-T6 minimum strength.
