Tungsten Carbide Copper Rod
Introduction
Tungsten carbide copper rod is a kind of alloy combines by tungsten carbide and copper, the tungsten carbide content is from 50% to 70%, this kind of material with high mechanical strength and excellent resistance arc burning capacity. Tungsten carbide rod with excellent performance of tungsten carbide's high melting point, high boiling point, high strength and high hardness, and copper's high conductivity and good wear resistance.
Technical Specifications
| Grade | Class | Content (% wt.) | Hardness | Conductivity(%IACS) |
| WD10250E | TC5 | WC:50, Cu:50 | 94(HRB) | 45 |
| WD10256E | TC10 | WC:56, Cu:44 | 100(HRB) | 42 |
| WD10270E | TC20 | WC:70, Cu:30 | 37(HRC) | 30 |
Processing
Tungsten carbide copper rod use advanced mechanical alloying production technology replaces the traditional method of powder metallurgy powder mixed, which improve the degree of fine material internal organizational structure. So that the scope of application of the material from a specific high-current electrical switches, circuit breakers extended to most moderate current series of switches and circuit breakers. The alloy material reduced WC content, increased the percentage of Cu has good conductivity, to improve the conductivity of the material, the effect of reducing the resistivity of the material in the effective control of the use of temperature rise, the heat burning contact technical issues, while adding an appropriate amount of C and trace amounts of Ti, rare earth elements, and further improve the material's welding resistance, electric wear resistance, electric arc overall performance, electrical life and so on.
