UCT’s patented Nickel Boron plating, known as EXO, creates a competitive advantage across many industries and applications. UCT's Nickel Boron has a higher boron content than any other commercially available NiB. That results in increased hardness and wear resistance. Parts coated with the Nickel Boron run longer and require less maintenance. The coating greatly enhances heat dissipation so treated products run cooler than non-treated parts.
EXO is a patented, nodular Nickel-Boron (NiB) surface treatment. The coating nucleates on the surface atoms of metals, becoming part of the metal rather than merely applied to the outside. In addition, the treated surface becomes harder than the substrate itself, eliminating the cost, weight and degradation problems of conventional hardened metals.
