7049 铝合金

7049 aluminum is a high-strength 7xxx series alloy with high zinc and copper content, formulated primarily as a forging grade. It offers excellent resistance to stress-corrosion cracking and good machinability, which makes it a frequent choice for critical structural forgings in aerospace and missile applications. It is generally considered non-weldable and is best supplied as forged or machined parts. Linsy supplies 7049 in plate, bar, and forging stock with mill test certificates on every order.

可选格式: plate, bar / rod, forging stock
常见脾气: F, H112, O, T352, T6, T651, T73, T7451
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

  • O — Annealed, softest condition.
  • T6 / T651 — Peak-aged; highest strength, lower corrosion resistance.
  • T73 / T7451 — Overaged for maximum stress-corrosion resistance; preferred for critical aerospace forgings.
  • T352 — Solution heat-treated and retrofit aged for forgings.

主要特点

强度极高

Among the strongest 7xxx forging alloys.

Excellent stress-corrosion resistance (overaged)

T73 / T7451 tempers resist cracking in aggressive environments.

良好的机加工性能

Cuts cleanly on CNC equipment.

Generally non-weldable

Design as forged or machined parts; welding is not recommended.

应用

  • Aerospace and missile structural forgings
  • Landing-gear and high-load components
  • Defense and ordnance parts
  • High-strength machined blocks
  • Critical fatigue-rated structures

加工与表面处理说明

Linsy supplies 7049 as plate, bar, and forging stock, then CNC-machines and laser-cuts to print. It is not recommended for welding. For corrosion protection, anodizing or painting is advised, and the T73 / T7451 tempers should be specified where stress-corrosion resistance is critical.
