7022 aluminum is a high-strength Zn-Mg-Cu alloy in the 7xxx series, combining zinc, magnesium, and copper for elevated strength and good machinability. It is often chosen for tooling, mold making, and high-stress machined components where dimensional stability after machining matters. Linsy supplies 7022 in sheet, plate, and bar with mill test certificates on every order. Note: mechanical values below should be confirmed against the mill certificate before release.
Available forms: sheet / plate, bar / rod
Common tempers: T6, T651
Processing support: CNC machining, laser cutting, TIG/MIG welding, anodizing, polishing, powder coating
Quality documents: MTC report with every order

7022 aluminum (EN AW-7022, AlZn4.5Mg1) 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), and ASTM B313 (welded tube). Forging stock follows ASTM B247. Always confirm the exact specification and temper with our team for your order.

Values are typical for the indicated condition. An em dash (—) means the value was not available in the source data; confirm with the mill certificate. Asterisked values are estimates pending verification — see the audit report.
Among the stronger medium-zinc 7xxx grades, close to 7075 in the T6 condition.
Holds tight tolerances and a clean finish in high-speed milling.
T651 minimizes distortion after removal of stock.
Generally considered non-weldable; design as a machined part, not a welded assembly.
Linsy machines 7022 on CNC centers for molds and precision parts and laser-cuts plate. It is not recommended for welding; for corrosion protection use anodizing or painting. Stress-relieving (T651) is advised for finished machined parts.
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.

Generally no. 7022 is supplied for machined and formed parts rather than welded assemblies; choose 7020 or 7021 if welding is required.
Tooling, injection molds, and high-stress machined components where strength and stability after machining are critical.
