7022铝合金

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.

可选格式: sheet / plate, bar / rod
常见脾气: T6, T651
处理支持: CNC 加工、激光切割、TIG/MIG 焊接、阳极氧化、抛光、粉末喷涂
质量文件: 每笔订单均附有MTC报告

硬度选择指南

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

主要特点

高强度

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

良好的机加工性能

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

尺寸稳定性

T651 minimizes distortion after removal of stock.

Not for welding

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

应用

  • 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

加工与表面处理说明

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.

订单附带哪些文件?

每笔订单均附带 MTC,可根据要求提供 SGS 第三方测试报告。.
