Aluminium, Commercial Alloy
6005A T6 Bar & Extrusion
내식성이 뛰어난 중간 강도의 열처리 가능 합금입니다.
Aluminium alloy 6005A is a medium strength, heat treatable alloy with excellent corrosion resistance. It is often used in transport and structural engineering applications.
Alloy 6005 has properties between those of alloys 6061 and 6082 and can sometimes be used interchangeably with these alloys, but 6005 has better extrusion characteristics and a better mill surface finish. It is difficult to produce thin-wall or complicated extrusions in 6005, but it is still more extrudable than 6082.
