Electroforming



Metals & Alloys

Structural Electroforming For Engineering Applications


Nickel

Electroformed nickel is produced from the sulfamate electrolyte. Typical mechanical properties for engineering applications meet the following range:

  • Ultimate Strength, Ksi 90 to 120
  • Yield Strength, Ksi 60 to 80
  • Elongation, % 10 to 20 ​

Nickel / Cobalt

An alloy of nickel/cobalt is used when high strength is required and the alloy will not be exposed to temperatures exceeding 450 degrees Fahrenheit (232 degrees Celsius). Nickel/Cobalt may be deposited in cobalt percentages from 3 to 55. Mechanical properties vary with percentage of cobalt.


Copper

We have the ability to deposit copper with a wide range of mechanical properties based on the application of the product. Copper may be deposited with relatively high tensile properties for structural applications or very high purity (OFHC) for electrical or thermal conductivity. Typical analysis for high purity (OFHC) copper meets the following limitations:

  • Oxygen less than 10 ppm
  • Hydrogen less than 5 ppm
  • Nitrogen less than 15 ppm
  • Sulfur less than 18 ppm

As deposited, mechanical properties of the high purity copper may be varied over a wide range as follows:

  • Ultimate Strength, Ksi 32 to 55
  • Yield Strength, Ksi 16 to 35
  • Elongation, % 20 to 40

Mechanical properties of electroformed copper can be maintained over a very great thickness based on our ability to maintain microstructural grain size and uniformity.
