HOME METALS ALUMINIUM AEROSPACE ALUMINIUM ALLOYS QQ-A-200/3 T3511 (2024) Bar & Extrusion

Aluminium, ASTM & FED-QQ

QQ-A-200/3 T3511 (2024) Bar & Extrusion

High strength aerospace aluminium alloy.

A high strength alloy with, dependent upon temper, minimum proof stress up to 56 ksi/385 MPa and minimum tensile strength up to 70 ksi/482 MPa.

It is excellent on parts where good strength-to-weight ratio is needed and for use in high strength applications where no welding is required.
