Stop aluminium 7075

7075 aluminum is the best-known high-strength 7xxx series alloy, with zinc as the principal hardener and copper and magnesium as major additions. In the T6 and T651 tempers it reaches strength comparable to many steels while staying light, which is why it has been the aerospace and performance-engineering standard for decades. Its corrosion resistance is lower than 6xxx grades, so exterior use usually calls for cladding or coating. Linsy supplies 7075 across the full form range — sheet, plate, tube, bar, wire, and profile — with mill test certificates on every order.

Dane techniczne i odpowiedniki oznaczeń

7075 aluminum (EN AW-7075, AlZn5.5MgCu) is supplied to common wrought-alloy specifications. Typical standards by form: ASTM B209 (sheet and plate), ASTM B221 (extruded tube, bar, and profiles), ASTM B211 (bar and rod), ASTM B247 (forging stock), and ASTM B313 (welded tube). Always confirm the exact specification and temper with our team for your order.

Przewodnik po doborze hartowania

  • O — Annealed, softest condition for forming.
  • T6 — Peak-aged; maximum strength for the alloy.
  • T651 — Stress-relieved T6; preferred for machining and plate.
  • T73 / T7451 — Overaged for much better stress-corrosion resistance; used where corrosion matters.
  • H112 — As-fabricated plate, no special heat treatment.

Kluczowe cechy charakterystyczne

Benchmark high strength

7075 Aluminum FAQ

What is 7075 best for?

Applications where maximum strength-to-weight matters: aircraft structures, performance automotive, bike frames, and tooling.

T6 or T651 — which should I choose?

T651 is stress-relieved and the usual choice for plate and bar where machining stability matters; T6 is the peak-aged baseline.

Is 7075 corrosion resistant?

Less so than 6xxx alloys. Use T73/T7451 tempers or cladding/coating for corrosive environments.

Can 7075 be welded?

It welds poorly and loses strength in the heat-affected zone. For welded builds, ask us about 6061 or a qualified welding-grade alternative.

Jakie dokumenty są dołączane do zamówienia?

Every order ships with an MTC, and SGS third-party test reports are available on request.
