I. Introduction to Carbide Washer

Tungsten carbide washers, circular constituents that display high resistance to wear, hardness, deformation, and corrosion, are deployed in mechanical applications that necessitate these attributes. The washers are comprised of a composite amalgamation of tungsten carbide particles and a metallic binder.

These washers frequently serve as sealing rings in diverse equipment such as valves, pumps, and other mechanical equipment that mandates an airtight seal to prevent any fluid seepage. The utilization of tungsten carbide for sealing applications arises from its exceptional resistance to wear and corrosion, making it an excellent candidate for components that are frequently exposed to abrasive media and demanding operating conditions. Moreover, these tungsten carbide washers come in diverse shapes, sizes, and configurations, tailored to meet the specific needs of various mechanical applications.

II. Grades of the carbide washer

Grade Density T.R.S MPa Hardness HRA Performance & application recommended
YG6A 14.95 1800 92.5 Fine-grained alloy, great wear resistance. Semi-finishing and finishing of chilled cast iron, non-ferrous metals alloys, hardened steel, alloy steel.
YG8 14.8 2200 89.5 High strength in use, higher impact resistance than YG6, but comparably lower wear resistance and cutting speed. Applied in the roughing of cast irons, non-ferrous metals and their alloys as well as nonmetallic materials at low cutting speed.
