Super Hard Material Tungsten Carbide Pins With Transition Metal

Introduction:

Tungsten carbide is a major component of cemented carbide materials. As hard phase of refractory metal, the tungsten steel is used with transition metal (Co, etc.) as the binder phase. The super-hard material prepared by powder metallurgy technology is cemented carbide. Cemented carbide has the advantages of high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance and small coefficient of linear expansion. It is one of the excellent tool materials, widely used in many industrial production and processing operations. Especially for the use of precision mold equipment, such as the tungsten carbide is processed into tungsten steel pin used in the AR8 anti-vibration rotor core stamping mold. Material performance is the basic use requirement, and long-lasting life is the efficiency guarantee for industrial mass production.

Technical parameters:

Good physical stability is the basic requirement for tungsten carbide products. It is can be used in special conditions for its excellent performance of wear resistance, high temperature resistance and corrosion resistance. This is how the excellent performance tools can directly improve production efficiency. We can provide punching pins and sleeves used for precision mold parts, we can also produce tungsten steel inner and outer rotor pin, rotor forming pin, rotor metering pins, etc. according to the core stamping mold requirements of the customers. According to the actual operation requirements and customer's specific drawing as the precision tolerance standard, we provide non-standard forming of tungsten carbide. The physical parameters of conventional tungsten carbide non-standard forming pin production materials can be referred to as follows:

• Grain size (um): 0.8 ~ 2.0
• Cobalt content (Co%): 6 ~ 10
• Density (g/cm³): 14.45
• Hardness (HRA): 88 ~ 92
• Bending strength (Mpa): 3200 ~ 3800
• Young's modulus (Gpa): 570
• Compressive strength (Mpa): 4700
