Chromium Carbide Overlay Plates (CCO Plates)
Premium Wear Plate Solutions by Leomet Alloys
Our Brands: BOROTUFFâ„¢ | CHROMOTUFFâ„¢
Product Overview
BOROTUFFâ„¢ and CHROMOTUFFâ„¢ are next-generation Chromium Carbide Overlay
(CCO) plates, crafted using precision German overlay technology by RBD Global. Designed
to deliver exceptional wear resistance in environments subjected to severe abrasion,
erosion, and moderate impact.
Ideal for industries such as cement, mining, power, steel, and recycling, these plates are
built for durability, efficiency, and long service life.
