YD Type Hard Alloy Welding Rod (Abbreviated as YD Type Welding Rod):

It is made by mixing granular sintered hard alloy with elastic matrix alloy. Coated with a special flux and colored to indicate the particle size grade. The sintered hard alloy particles are mainly cobalt tungsten carbide, with a hardness of HRA 89-91; the matrix metal is "nickel copper" alloy, with a tensile strength of 690MPa and hardness: HB≥160.

Primarily used for surfacing workpieces that are subject to severe wear or require cutting in industries such as oil, mining, coal mining, geology, and construction. Examples include: milling shoes, grinding shoes, aligners, boring bars, hydraulic cutters, scraper blades, coal cutter bits, core drill bits, pile drilling bits, and helical drill bits.

Supplied in eight grades according to the size of the hard alloy particles.
