7053 aluminum is a high-strength 7xxx series alloy with high zinc and copper content, developed for demanding structural use where strength and durability matter. It offers tensile levels above many common aerospace grades and is specified for aircraft structures and heavy-duty components that must hold up under sustained stress. Linsy supplies 7053 in plate, tube, bar, and wire with mill test certificates on every order.
Available forms: plate, tube, bar / rod, wire
Common tempers: T7451, T77, T7751
Processing support: CNC machining, laser cutting, TIG/MIG welding, anodizing, polishing, powder coating
Quality documents: MTC report with every order

7053 aluminum (EN AW-7053, AlZn6.5Mg1.3Cu) 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 for the overaged T7451 / T7751 tempers. The wide shear range in the source should be confirmed with the mill certificate.
Tensile above many common aerospace alloys.
Overaged tempers suit demanding service.
Precipitation hardened to specification.
Supplied as machined or formed parts.
Linsy machines and laser-cuts 7053 and applies anodizing or painting for corrosion protection. Welding is not recommended.
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.

Aircraft and heavy-duty structural parts where strength above common grades is required.
Plate in T7451; wire and extrusions in T77 / T7751 overaged tempers.
No, it is a machined-part alloy rather than a welding grade.
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.
