◆ Cobalt-Tungsten Carbide spray powder (agglomeration sintering)

Symbol	Hardness(Hv)	Chemical Composition	Typical Characteristic
UM-WC-Co 08	1200	Co8.0,C5.5,W (Bal)	The coating surface is dense, hard and wear-resistant
UM-WC-Co 12	1200	Co12.0,C5.2,W (Bal)	The abrasion resistance is strong at 550℃, which can increase the corrosion resistance and wear resistance
UM-WC-Co 17	1200	Co17.0,C4.9,W (Bal)	Compared with the WC-C12 series, the cobalt content is increased, making the toughness, impact strength and ductility more excellent C-12Co,provide better toughness,impact strength and malleability
UM-WC-Co 10Cr4	1200	Co9.5,Cr4.0,C5.1 6,W(Bal)	Compared with the WC-Co series and the WC-Ni series, its antioxidant capacity and corrosion are greatly improved

Comment: Typical use cases are for supersonic spraying.
