Powder metallurgy series grades

Cracking and wear resistance issues often occur during the pressing of powder products such as copper powder, iron powder, tungsten carbide, ferrite, zirconia, and alumina. We consider the diversity and complexity of product structures and design multiple specialized grades to select materials correctly based on material characteristics for different purposes.

series	brand	Cobalt content (%)	Density (g/cm3)	hardness	Bending strength (Mpa)	Application scope
Powder metallurgy series	CF06F	6	14.90	93.3	≥3200	Ultra fine grain, extremely high wear resistance and excellent strength. Suitable for high-pressure molds with simple cavities such as soft magnetic materials, used as negative molds.
	CF10F	10	14.60	92.3	≥3800	Ultra fine grain, high wear resistance. Suitable for high-pressure molds with simple cavities such as soft magnetic materials, used as negative molds and core rods.
	CF20	7	14.75	91.0	≥3200	Suitable for powder metallurgy molds such as iron-based and copper based molds, used as negative molds, shaping molds, and core rods.
	CF40	10	14.62	89.5	≥3200	Suitable for iron-based, copper based, and hard alloy powder metallurgy molds, used as negative molds and core rods.
	VG05	12	14.32	89.0	≥3300	It has high strength and wear resistance, suitable for forming concave dies and punches of iron powder, copper powder, and hard alloys with complex shapes and high pressing pressures.
	VG30F	20	13.80	88.0	≥3400	Strengthening the liquid phase and using ultrafine grains results in strong fatigue resistance. Suitable for powder metallurgy molds such as iron-based and copper based molds, used for the production of irregular and curved punch heads.
	VG15	14	14.15	87.5	≥3500	Good toughness, impact resistance, and good spot processing ability, suitable for high load work and complex mold cavities.
