7022 알루미늄 합금

What Is 7022 Aluminum?

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.

템퍼 선택 가이드

• T6 — Solution heat-treated and artificially aged; highest strength for tooling and structural use.
• T651 — Stress-relieved T6; improved dimensional stability for precision machining.

주요 특징

높은 강도

Among the stronger medium-zinc 7xxx grades, close to 7075 in the T6 condition.

우수한 가공성

Holds tight tolerances and a clean finish in high-speed milling.

치수 안정성

T651 minimizes distortion after removal of stock.

Not for welding

Generally considered non-weldable; design as a machined part, not a welded assembly.

애플리케이션

• Injection molds and high-pressure forming tools
• Aerospace structural and airframe parts
• High-stress machine components
• Precision base plates and fixtures
• Defense and sporting equipment

가공 및 표면 마감 참고 사항

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.

7022 Aluminum FAQ

Is 7022 weldable?

Generally no. 7022 is supplied for machined and formed parts rather than welded assemblies; choose 7020 or 7021 if welding is required.

What is 7022 used for?

Tooling, injection molds, and high-stress machined components where strength and stability after machining are critical.

Why are the mechanical values marked with an asterisk?

The source data for this page was incomplete and partly copied from another grade. The values shown are typical estimates and must be verified against the mill certificate before use.

What documents come with the order?

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

주문 관련 일반적인 자주 묻는 질문

일반적인 리드 타임은 얼마인가요?

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.

Can I get a mill test certificate?

Yes. Every order includes an MTC. SGS third-party test reports are available on request.

Do you offer machining and finishing?

Yes. We provide CNC machining, laser cutting, welding, anodizing, polishing, and powder coating so parts can be delivered closer to finished form.
