General Details and Specification of nickel plated finishes
There is a nickel finish for almost any need, Nickel can be deposited soft or hard, dull or bright, depending on process used and conditions employed in plating. Hardness can range from I SO-SOO Vickers. Can be similar to stainless steel in color, or can be a dull gray or light gray (almost white) color. Corrosion resistance is a function of thickness. Has a low coefficient of thermal expansion-is magnetic. All steel parts having a hardness of Rc-40 or greater require a post bake at 375 + 25 F for 3 hours.
Bright Nickel is great for fasteners and finish, Hand tools, & Household lighting and plumbing fixtures
Benefits of nickel plating
- The bright Nickel offers a decorative finish
- Wear resistant
- Corrosion resistant
- Good diffusion barrier
- Magnetic
- Suitable for either Rack or Barrel plating
