Aluminum

Brazing/Welding

Aluminum is considered to be a “light” metal, having a melting point between 1100F and 1300F. Types of aluminum that braze well and are heat treatable are 6061, 6062, 6063, and 6951. Other aluminums that braze well but cannot be heat treated include 1100, 5052, and 3003. Aluminum casting materials can be metal type 710, 711, or 712. There are other types of aluminum that can be joined by soldering, which usually occurs after the components have been nickel-plated.

Temperature:
  • + or - 840F
Common Equipment:
  • Molten Salt Furnace
  • Vacuum Furnace
  • Oxy-Acetlyene Torch
Common Material:
  • Hardenable (6061, 7075)
  • Castings (356, 712)
  • Non-hardenable (1100, 3003, 5052)

Heat Treating

Heat treating of aluminum has several types of styles. While stress relief, annealing, and solutioning are used to remove stress and reduce hardness, solution, quenching and artificial aging are used to restore hardness or harden beyond the natural hardness. Individually, stress relief relieves stress caused by machining or cutting, annealing removes all stress and some of the hardness, and solutioning removes all of the hardness. Solution and quenching restores the natural hardness or material, while artificial aging harden the material beyond its natural hardness.

Secondary Operations

Aluminum secondary operations include a wide variety of services for Aluminum. We offer welding, including TIG, MIG, and tack welding. We can thermal (shrink) fit, straighten, blast or etch your parts, and test and certify the hardness. We also offer Helium Leak Detection, and direct coordination with other processes such as chem-film and paint.
