How Is Tungsten Carbide Copper Rod Manufactured?

The production of tungsten carbide copper rod typically involves copper infiltration and powder metallurgy process, which is a method of manufacturing metal parts from metal powders. Here is a general overview of production steps:

1.Powder Mixing:

Tungsten powder and cobalt powder are accurately weighed and thoroughly mixed to achieve a homogenous blend. The content is determined based on the desired properties of the final alloy.

2.Compaction:

The mixed powders are pressed or compacted into a green compact. The compaction is typically done under high pressure to form a preliminary shape of the rod. This green compact retains its shape but is porous.

3.Pre-Sintering:

The green compact is pre-sintered in a furnace at a lower temperature than the final sintering temperature. This step helps to partially bond the particles and remove some of the porosity, making the structure more robust for the subsequent infiltration process.

4.Copper Infiltration:

The pre-sintered tungsten carbide compact is then infiltrated with molten copper. This process involves placing the pre-sintered compact in a furnace where copper is melted and drawn into the porous structure of the tungsten carbide. The copper infiltration fills the voids between tungsten carbide particles, creating a fully dense and integrated composite material.

5.Sintering:

The infiltrated compact is subjected to a final sintering process at a higher temperature. This step allows the tungsten carbide and copper to fully bond and results in the densification of the material. The sintering temperature is carefully controlled to avoid melting the copper.

6.Machining and Finishing:

The sintered WCu composite is machined to achieve the final dimensions and surface finish. Machining processes may include turning, milling, or grinding.

7.Quality Control:

The finished tungsten carbide copper rods undergo rigorous quality control checks to ensure they meet specified standards. This includes dimensional checks, hardness testing, and other quality assessments.

This powder metallurgy and copper infiltration process results in tungsten carbide copper rods with a uniform distribution of tungsten carbide particles in a copper matrix, providing a balance of hardness, wear resistance, and thermal and electrical conductivity.

Tungsten Copper Alloy: A Versatile Material for Demanding Applications

Tungsten copper alloy combines the advantages of copper and tungsten, with the advantages of high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical and thermal conductivity and good processing performance.

Given that, it has various applications as following:  

Electrical Contact Material

Owing to high temperature resistance and electric ablation resistance, in the 1960s, some advanced countries used tungsten-copper alloys to manufacture electromagnetic fuses, throat linings on rockets and missiles, and other components. In addition, in the field of electrical contact, the performance of the contact material basically determines the development trend of the high-voltage switch. Tungsten-copper alloy material has high conductivity, electric ablation resistance and good breaking performance, and is widely used as contact material for high-voltage and ultra-high-voltage switching appliances.

Heat Sink Material

As a heat sink material, the material has high requirements for the uniformity of the structure, air leakage rate, thermal conductivity, and thermal expansion coefficient. Therefore, according to actual needs, tungsten-copper alloy materials can be adjusted by using tungsten and copper elements to change the thermal expansion coefficient and thermal conductivity, which can effectively avoid fatigue damage caused by thermal stress and affect the performance of tungsten-copper alloy materials. At the same time, the alloy material is widely used in inserts, connectors and heat dissipation components because tungsten and copper are composite materials, and have gradually become important heat sink materials.

Electrode Material

Electrode material is a key material in EDM, and it is directly related to stability, precision, and surface roughness of joints. Due to the relatively poor ablative properties of general electrode materials and high motor consumption, the processing accuracy is relatively poor, and even multiple processing is required. For this reason, with the development of tungsten-copper alloy materials, in order to solve the disadvantages of EDM, the WCu alloy material can be used to make electrical machining electrode materials, which can not only effectively improve the accuracy and reliability of machining, reduce electrode consumption.
