Rhodium plating

Rhodium plating

We provide rhodium plating as for a wear resistant and high abrasion/corrosion resistant plating deposit.
The electrical resistance of rhodium is the lowest in the platinum metal group (Pt, Pd. Ru, Rh, Ir).
The hardness of rhodium plating is about Hv800 ~ 1000 as a hard deposit.
Rhodium plating is used for the electrical contacts which are demanded to have strong wear resistance and high surface hardness. We have many years of experience in providing for the sliding contact.
Rhodium plating deposit is also used in the decorative fields and the industrial fields, because it has good corrosion resistance and is chemically stable.
However, rhodium plating deposit has high stress, therefore the cracks occur easy in a thick deposit. Rhodium has the following properties.

  • Brilliant reflective appearance and the appearance never change.
  • Excellent wear and abrasion resistance.
  • Low electrical resistance.
  • Low and stable contact resistance.
  • High corrosion resistance.
