What is Nickel Free Plating?
What is nickel free plating?
Getting same or stronger corrosion resistance with nickel plating with coating more than 3 micron copper tin alloy plating instead the same thickness of nickel plating. That's call nickel free plating.
Why Autron use nickel free plating?
Because the nickel element will have allergic reaction to our skin and blood and be bad to our healthy, therefore the modern environmental protection electroplating has replaced the nickel plating with the copper tin alloy electroplating.
Advantages of nickel free plating.
Because the copper tin alloy coating has excellent low current and good density, under the same thickness with nickel plating, the corrosion resistance is better than the nickel coating.
