Nickel plating provides a good corrosion and wear resistance deposit at a relatively low cost, while providing a high luster and bright decorative deposit, appealing to the eye. It is widely utilized in components requiring corrosion resistance on copper, brass, stainless and steel alloys, including medical, aerospace, common house hold items, and the oil and gas industry.
What Are The Benefits Of Nickel Electroplating?
Electroplating nickel develops and enhances several characteristics in the nickel base material:
- Increases strength and hardness
- Improved chemical and corrosion resistance
- Improved external appearance with nickel-plating chemicals
Industrial Applications
For engineering applications, nickel is applied on contacts and connectors for its high solder ability properties as well as an anti-diffusion layer between copper and gold, increasing corrosion and wear resistance of gold plated components.
Our rack, barrel, and vibratory process lines are set up to process nickel plating on millions of components a month, including contact pins, contact rings, and various other components for wide range of industries, including oilfield, oil & gas, electronics, medical, air defense, military, aerospace, etc.
Nickel Electroplating vs. Electroless Plating
GPT also offers electroless nickel plating services for your applications. Both plating techniques have their own unique features and benefits, that you can learn more about in our own comparison.
