Carbide Punch Bar Tungsten Steel Round Bar Custom Made Production

Cemented carbide is an advanced composite material produced by combining metal carbide powders with cobalt binder. This material incorporates tungsten carbide, titanium carbide, tantalum carbide, and vanadium carbide to enhance its properties, resulting in exceptional hardness and superior wear resistance.

This high-efficiency tool material is manufactured through powder metallurgy, where high-melting-point, high-hardness metal carbide powders are mixed with binder materials and pressed into various shapes. This process ensures the cemented carbide maintains optimal hardness, strength, and toughness characteristics.

Our comprehensive production process ensures quality from raw materials to finished products: ingredient mixing → pulverization → drying → sieving → forming agent addition → re-drying → sieving → mixture preparation → pressing and granulation → forming → low-pressure sintering → sintered blank → inspection (including non-destructive ultrasonic testing) → dimensional accuracy verification → EDM/wire cutting → rough grinding → fine grinding → polishing → final inspection → marking → packaging.
