Product Description
NiColoy® is NiCoForm, Inc.'s class of proprietary electrodeposited Nickel-Cobalt alloys distinguished by the following combination of features:
  • Leveled, smooth matte to semi bright deposit with low internal stress
  • High tensile strength
  • Medium-to-high hardness
  • High modulus of elasticity
  • High corrosion resistance
  • High purity
  • Amenable to soldering, brazing and welding

We produce two modifications of NiColoy® - high strength and high hardness, depending on the target application. The harder deposit is more suitable for mold inserts and mold repair applications. The high strength deposit exhibits a unique combination of elasticity and plasticity and is used to electroform bellows, diaphragms and other dynamic components. Please see the accompanying table and charts for a comparison of properties of the two types of NiColoy®.
