Spherical Metal Powders Cast Tungsten Carbide (WC) Powder

Product Character Spherical cast tungsten carbide powder is suitable for producing wear-resistant coatings through processes such as plasma transfer arc welding (PTA), laser cladding, and thermal spraying due to its unique preparation process and excellent performance. A coating made of spherical cast tungsten carbide as the hard phase and molten nickel, cobalt, and iron alloys as the bonding phase can strengthen the surface of mechanical parts, improve wear resistance, and extend service life. It has broad application prospects in mining, oil drilling, engineering machinery, aerospace and other fields.   2.Specification Spherical Cast Tungsten Carbide Powder
