Copper & Brass

Brass

A 70% copper & 30% zinc alloy, CDA 260 (C26000) brass in Half Hard temper is highly ductal, formable, and corrosion resistant.

Materials are processed by photo and chemical etching, laser and waterjet cutting, and precision stamping. These alloys are used in manufacturing a variety of products for commercial and aerospace applications:

  • Shims
  • Laminated shims
  • Gaskets
  • Washers
  • Formed parts
  • Automotive
  • Marine
  • Medical
  • Aircraft / Aerospace / Military
