What is corrosion and tarnishing?
The most common defect on hardware is corrosion and tarnishing, where the product changes colour, goes rusty or the surface oxidizes. Low-quality hardware usually causes corrosion and tarnishing, due to an inadequate alloy and/or ineffective plating coverage or thickness.
Why test your hardware and jewellery for corrosion and tarnishing?
To ensure a high standard of product quality, all hardware and jewellery items need to first be tested as part of your due diligence process.
