Miralloy™ Plating
Miralloy™ plating from General Metal Finishing delivers a reliable, nickel-free metal finish that provides excellent corrosion resistance and functional performance across a range of industrial applications. Designed as an advanced alternative to traditional nickel and silver plating, Miralloy™ coatings are ideal for parts that require durability, reduced skin-sensitivity concerns, and robust surface properties.
What Is Miralloy™ Plating?
Miralloy™ is a family of copper-tin-zinc alloy electroplated finishes that create bright white or yellow metallic coatings with unique performance advantages. Unlike conventional nickel plating, Miralloy™ is nickel-free, diamagnetic, and free of heavy metals such as chromium, lead, and cobalt, making it an excellent choice for applications where regulatory compliance and surface performance matter.
Benefits of Miralloy™ Plating
- Nickel-free plating – Ideal for applications where nickel or other heavy metals must be avoided
- Excellent corrosion resistance – Provides robust protection against rust and environmental attack
- High hardness and wear resistance – Typical coating hardness values up to ~550–600 HV
- Bright, uniform finish – Available in white or yellow alloy tones with high brightness and a smooth appearance
- RoHS and regulatory compliant – Meets many industrial standards for restricted substances
- Compatible with additional finishes – Can be combined with precious metal plating topcoats if required
Typical Miralloy™ Plating Applications
Miralloy™ plating is widely used across industries where both performance and surface quality are important. Common applications include:
- Electronic connectors and components
- High-frequency and RF contacts
- Hardware and precision parts with skin-contact requirements, especially those in the medical industry
