Introduction

Aluminum 6026 is a wrought alloy. It has excellent corrosion resistance and is ideal for anodizing so can provide both decorative and hard anodized finishes. However aluminum 6026 contains little tin, which can cause machined parts to become weak and crack when subjected to stress and high temperature.

The following datasheet will provide more details about aluminum 6026 alloy.

Fabrication

The most common temper for aluminum 6026 alloy is T9, which is solution heat treated, artificially aged and cold worked. It can be used as a substitute for aluminum 6082 or 6081 alloy especially when finished parts require prolonged machining on high-speed automatic lathes. This alloy can be welded.

Applications

Aluminum 6026 alloy is chiefly used in the following applications:

  • Decorative anodizing
  • Machined parts
  • Hard anodizing
  • Automotive components such as brake systems
  • Hot forging
  • Electrical and electronic parts
