The Production Method Of W70Cu30 Tungsten Copper Alloy Round Rod

The production of W70Cu30 tungsten copper alloy round rods involves several steps to achieve the required composition, microstructure and mechanical properties. The following is a brief introduction to the production method of W70Cu30 tungsten copper alloy round rod:

1. Raw material preparation: The production process must first select high-purity tungsten and copper raw materials. Tungsten powder and copper powder are usually used as starting materials. Weigh the powder carefully and mix in appropriate proportions to obtain the desired W70Cu30 composition.

2. Mixing and compacting: Mix the tungsten powder and copper powder together to form a uniform mixture. The mixed powder is then compacted under high pressure using a process such as cold isostatic pressing (CIP) to form a green body with the desired shape, such as a rod.

3. Sintering: The green body is sintered in a high temperature furnace under controlled atmosphere conditions. During sintering, the powders are heated to temperatures below the melting points of the components, causing them to bond together through a diffusion process. This results in the formation of a solid, dense tungsten-copper composite.

4. Thermal processing (optional): In some cases, sintered tungsten copper materials may undergo thermal processing processes such as extrusion or forging to further refine the microstructure and improve the material's mechanical properties.

5. Machining and finishing: The sintered material and possibly thermally worked material are then machined to the desired final dimensions and surface finish of the round bar. This may involve turning, grinding and other machining processes to achieve the desired shape and surface quality.

6. Quality control: During the entire production process, quality control measures are implemented to ensure that the composition, size and mechanical properties of the tungsten copper round rods meet the required specifications.

The production of W70Cu30 tungsten copper alloy round rods involves precision manufacturing processes and may require specialized equipment and expertise due to the unique properties of tungsten and copper. Additionally, due to the potential health hazards associated with metal dust, safety measures should be taken when handling tungsten and copper materials, especially in powder form.
