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.
Available forms: sheet / plate, tube, bar / rod, wire
Common tempers: F, H112, O, T6, T651, T7451
Processing support: CNC machining, laser cutting, TIG/MIG welding, anodizing, polishing, powder coating
Quality documents: MTC report with every order

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.

Values are typical AA 7075 figures by temper; the soft O condition and peak T6 / overaged T73 differ widely. Confirm exact numbers with the mill certificate.
Decades of use as the reference strong aluminum alloy.
Steel-like strength at a fraction of the mass.
Clad sheet or coatings recommended for exterior service.
Generally supplied machined or bonded, not welded.
Linsy machines 7075 on CNC centers and laser-cuts plate and sheet. Anodizing or painting improves corrosion resistance; clad sheet is available for exterior use. Welding is not recommended — for joints, consider 6061 or a welding-grade 7xxx with our team.
Linsy is a Shenzhen-based aluminum supplier with more than 20 years of experience. Our quality system is certified to ISO 9001, ISO 14001, and ISO 45001. Every order ships with a mill test certificate (MTC). SGS third-party test reports are available on request. Typical custom lead time is 10–60 days depending on temper, size, and quantity.
Explore these in-depth guides from our technical library:
Applications where maximum strength-to-weight matters: aircraft structures, performance automotive, bike frames, and tooling.
T651 is stress-relieved and the usual choice for plate and bar where machining stability matters; T6 is the peak-aged baseline.
Less so than 6xxx alloys. Use T73/T7451 tempers or cladding/coating for corrosive environments.
It welds poorly and loses strength in the heat-affected zone. For welded builds, ask us about 6061 or a qualified welding-grade alternative.
Every order ships with an MTC, and SGS third-party test reports are available on request.
Custom aluminum orders typically ship in 10–60 days depending on alloy, temper, size, and quantity. Stock or standard sizes may be faster — ask our team.
Yes. Every order includes an MTC. SGS third-party test reports are available on request.
Yes. We provide CNC machining, laser cutting, welding, anodizing, polishing, and powder coating so parts can be delivered closer to finished form.
Send your alloy, temper, dimensions, quantity, and required standard. Our team will confirm availability, lead time, and pricing.
