Buy Tungsten Carbide Rods

 The TOP 1 thing you should know before you buy tungsten carbide rods is the Co content and the average grain size of WC. 

As we all know, tungsten carbide rods and alloys are made of hard compounds of refractory metals such as tungsten carbide (WC) powder and bonding metals such as cobalt (Co) powder through powder metallurgy process/injection moulding technology / 3D printing process The material has the characteristics of high hardness, good toughness, wear resistance, heat resistance, and corrosion resistance. It is widely used in cutting tools, hardware moulds, aerospace parts and other fields. However, the physical and chemical properties of tungsten carbide rods are not static and are mainly affected by WC powder content, WC grain and Co content.

Generally, as the WC powder content increases, the hardness of the tungsten carbide rods increases, and the wear resistance becomes better, but the toughness becomes worse; as the WC grain decreases, the hardness of the alloy increases, and vice versa; The higher the cobalt content, the better the toughness of the alloy and the lower the hardness, and vice versa the worse the toughness and the higher the hardness.

Studies have shown that when the Co content is 6% and the average grain size of WC is 0.8μm, the density of tungsten carbide rods is 14.85-14.95g/cm3, the bending strength is greater than or equal to 3000MPa, and the hardness is 92.6HRA (±0.5), which is suitable for It is used in the manufacture and processing of non-metallic and non-ferrous metal tools.

When the Co content is 6% and the average grain size of WC is 0.4μm, the density of tungsten carbide rods is 14.5-14.7g/cm3, the bending strength is greater than or equal to 3500MPa, and the hardness is 94HRA (±0.5), suitable for powder metallurgy Processing and can be made into PCB (printed circuit board).

When the Co content is 8% and the average WC grain is 0.5μm, the density of the tungsten carbide rods is 14.4-14.6g/cm3, the bending strength is greater than or equal to 3600MPa, and the hardness is 93.3HRA (±0.5), suitable for hard ends Milling and fine milling, processing fibre, wood, plastic, brass, aluminium alloy, etc., can make PCB micro drills and carving knives.

When the Co content is 10% and the average grain size of WC is 0.8μm, the density of tungsten carbide rods is 14.35-14.5g/cm3, the bending strength is greater than or equal to 4000MPa, and the hardness is 91.7HRA (±0.5), which is suitable for processing cast iron. The first choice for aluminium alloy and various non-metallic materials; it is suitable for processing materials with a hardness lower than HRC55, and has good versatility.

When the Co content is 10% and the average WC grain size is 1.0μm, the density of tungsten carbide rods is 14.4-14.55g/cm3, the bending strength is greater than or equal to 3800MPa, and the hardness is 91.2HRA (±0.5), which can be used for ordinary end milling, Rough milling, suitable for HRC30-45 material processing.

When the Co content is 12% and the average grain size of WC is 0.4μm, the density of tungsten carbide rods is 13.95-14.25g/cm3, the bending strength is greater than or equal to 4000MPa, and the hardness is 92.5HRA (±0.5), suitable for processing grey cast iron, Titanium alloys, heat-resistant materials, stainless steel, hardened steel, glass fibre reinforced plastics and composite materials, suitable for high-speed processing.

When the Co content is 9% and the average grain size of WC is 0.2μm, the density of tungsten carbide rods is 14.2-14.4g/cm3, the bending strength is greater than or equal to 4000MPa, and the hardness is 93.7HRA (±0.5), which is suitable for processing high Strength, high wear resistance material.

When the Co content is 7% and the average grain size of WC is 0.5μm, the density of the tungsten carbide rods is 14.4-14.7g/cm3, the bending strength is greater than or equal to 3600MPa, and the hardness is 93.3HRA (±0.5), which is suitable for machine tools with relatively high rigidity. Good finishing can be made into a reamer, deep hole drill and PCB (printed circuit board)

When the Co content is 5% and the average grain size of WC is 0.4μm, the density of the tungsten carbide rods is 14.5-14.8g/cm3, the bending strength is greater than or equal to 3500MPa, and the hardness is 94HRA (±0.5), which has excellent wear resistance Sex, can be made into PCB.

When the Co content is 10% and the average grain size of WC is 0.5μm, the density of the tungsten carbide rods is 14.15-14.3g/cm3, the bending strength is greater than or equal to 4000MPa, and the hardness is 93.0HRA (±0.5), and the machinable hardness is in Materials between 45-65HRC can be used for milling high-temperature resistant steel, hardened steel, grey cast iron, heat-resistant alloy, titanium alloy, etc., suitable for high-speed processing.

When the Co content is 10% and the average grain size of WC is 0.6μm, the density of tungsten carbide rods is 14.4-14.55g/cm3, the bending strength is greater than or equal to 3800MPa, and the hardness is 92.1HRA (±0.5), suitable for machine tool rigidity It is better for processing stainless steel, aluminium alloy, grey cast iron, titanium alloy and glass fibre reinforced plastic.

Samples order :

Solid Tungsten Carbide Rods are just one material, that needs to be processed and reused, so the problem can occur in this process or our rods.
