Tungchip Tungsten Carbide Grit, is cemented Tungsten Carbide Cobalt chips. It is produced from specially selected and graded powders, which are sintered into solids before being broken down to grit. All Tungchip products are of premium quality, manufactured with care and attention in order to achieve and exceed international standards. Tungchip Tungsten Carbide Grit, being harder than Chromium Carbide and most traditional hard facing materials, provides an effective combatant against abrasion wear. Material is supplied in sizes from 12.7mm down to 45 micron. Particle shape is important, with the sharp blocky chips being used in cutting grade Composite Rod. The rounded blocky chips are used for GMAW, welding rods and wear grade Composite Rod. Deleterious materials are removed to avoid detrimental effects to the weld process. Quality checks including sizing, particle shape, chemical composition, oxide levels and cleanliness are undertaken during manufacturing and prior to delivery.
