What 7075-T6 aluminum plate is
7075 is a zinc-magnesium aluminum alloy — the strongest commercial aluminum, with yield strengths around 73 ksi. T6 is the solution-treated and aged temper that delivers full strength. Plate is supplied in mill finish per AMS-QQ-A-250/12 (aerospace) or ASTM B209 (commercial), in thicknesses from 0.25" through 6". The trade-off vs. 6061 is real: 7075 is harder to weld, less corrosion-resistant, and roughly 2-3× the cost.
What to look for in a supplier
Aerospace work usually calls for AMS-QQ-A-250/12 plate with full mill certs traceable to heat lot. Commercial buyers can use B209 plate. Decide whether you need T651 (stress-relieved) vs T6 — for machined parts, T651 is almost always the right answer. Confirm the supplier can hold AS9100 if aerospace traceability is required; some stocking distributors carry only B209 commercial-grade and can't quote the AMS spec. Cut tolerance, alclad vs. bare, and surface finish (mill, polished, or precision-fly-cut) belong on the PO.
FAQ
Common questions
What's the difference between 7075-T6 and 7075-T651?
Same alloy + temper, but T651 has been stretched 1.5-3% post-aging to relieve residual stress. For high-precision machined parts that would distort during stock removal, T651 is essential. For sheet-fab or as-formed parts, T6 is fine.
Is 7075 weldable?
Not practically. 7075 loses most of its strength in the heat-affected zone of a weld and is prone to cracking. For bolted, riveted, or adhesively-bonded assemblies 7075 is fine; for welded assemblies use 6061 or 5083 instead.
What's the difference between bare and alclad 7075?
Alclad has a thin layer of pure aluminum bonded to the surface for corrosion protection — important for aerospace exterior parts. Bare 7075 is what you want for machined components where the surface gets removed anyway, and for tooling work where the cladding would be machined off.
What lead time should I expect on 7075-T6 plate?
Common sizes from a stocking distributor: 1-2 weeks. AMS-spec aerospace plate from a qualified house: 2-4 weeks. Oversize or thick plate (>4") can run 6+ weeks.
