Luma Wire Tech provides precision rhodium plating solutions for applications requiring exceptional surface durability, wear resistance, and long-term reliability.
Through advanced reel-to-reel electroplating, we apply highly controlled rhodium coatings to ultra-fine wire dimensions ranging from 5 to 200 microns, enhancing existing wire materials with outstanding hardness, corrosion resistance, and electrical contact stability. Its unique combination of mechanical durability and functional performance makes it an attractive solution for demanding applications in medical technology, aerospace, electronics, and advanced industrial systems.
For customers seeking a premium coating capable of withstanding challenging operating environments and repeated mechanical stress, rhodium offers a highly durable and reliable surface engineering solution.

Rhodium plating is known for its exceptional hardness and wear resistance. It is often used to improve the durability and lifespan of electrical contacts and components exposed to repeated mechanical interaction. Rhodium also offers excellent corrosion resistance and surface stability.
