硬度选择指南

  • O / T4: for forming or welding before aging.
  • T6: maximum strength for structural and machined parts.
  • T651 / T6511: stress-relieved extrusions with better dimensional stability after machining.

主要特点

机械加工性能

6061 machines cleanly in T6, making it efficient for screw-machine products, fittings, and repeating components.

Structural Integrity

The square geometry provides predictable load paths for frameworks, jigs, and supports.

耐腐蚀性

Good in most atmospheric environments; anodizing adds a durable, decorative surface.

应用

  • Automatic screw-machine products
  • Fasteners, fittings, and machine parts
  • Structural frames and supports
  • Shafts, spindles, and bicycle components

加工与表面处理说明

  • 机加工: free-cutting in T6; use coolant and sharp tooling.
  • 裁剪: supplied cut-to-length; saw cuts are deburred before shipping.
  • 焊接: TIG/MIG compatible with 4043 or 5356 filler.
  • T6 状态机加工性良好;使用锋利刀具和合适的冷却液。 anodizing and polishing are available.

质量文件与检验

  • 工厂检验证书(MTC): O 和 T4 状态比 T6 状态更易成型;需注意最小弯曲半径。.
  • 检查: 焊接填充材料.
  • 标准: 通常使用 4043 或 5356 填充焊丝;很少采用焊后热处理。.
  • 表面处理: 阳极氧化和粉末涂层为标准工艺;阳极氧化前应避免污染。.
