ManufacturingHeavystone Lab manufactures value-added products based on heat treating conventional cemented tungsten carbide materials including straight WC-Co, WC-Co with grain growth inhibitor additives, and those with cubic carbide additives. Any current tungsten carbide tools can be reprocessed to add a Heavystone Surface™ ( i.e. a surface layer with a gradient of cobalt content) to achieve significantly improved performance* and wear resistance without sacrificing impact resistance.
Functionally graded WC-Co products include rock drilling inserts and cutters, construction tools, WC-Co rods, metal cutting inserts, and engineered wear parts such as mechanical seals, bearings, nozzles and so forth.
* The measure and definition of performance of manufacturing tools vary. In several different industrial testing tungsten carbide tools with Heavystone Surface™ achieved from 40% to over 100% performance gain.
