Nickel Platings

 
Nickel Platings
 

Nickel Plating for coating any metallic substrate material.

Specifications(Military, Federal, and ASTM)

Bright Nickel & Sulfamate Nickel

Nickel appearance can range from color of stainless steel to white, dull or bright; hardness range 150-500 Vickers. Corrosion resistance is a function of coating thickness. Has low coefficient of thermal expansion; is magnetic.

Deposit Thickness

CLASS 1: for corrosion protection

  • Grade A 0.0016" minimum thickness

  • Grade B 0.0012" minimum thickness

  • Grade C 0.0010" minimum thickness

  • Grade D 0.0008" minimum thickness

  • Grade E 0.0006" minimum thickness

  • Grade F 0.0004" minimum thickness

  • Grade G 0.0002" minimum thickness

CLASS 2: for engineering applications

Electroless Nickel

Nickel used when hard, smooth, uniform deposit thickness are required. Surface is easily brazed; solderable. Hardness is a function of heat-treating; (see below).

  • CLASS 1: as plated; not heat-treated

  • CLASS 2: not heat-treated to desired hardness
