The production of tungsten-copper alloy plates typically involves a process called infiltration. This method combines tungsten and copper into a composite material that exploits the properties of both metals. Here is an overview of the production process:

Powder preparation: The production process usually starts with the preparation of tungsten powder and copper powder. These powders are carefully measured and mixed in the required proportions to obtain the desired alloy composition. The mixing process is critical to ensure an even mix of the two components. Compaction: The mixed powder is then compacted under high pressure. This compaction process helps form green compacted parts of the desired shape and size. Compaction can be achieved using various methods, such as cold pressing or isostatic pressing. Sintering: After compaction, the green body is sintered at high temperature in a controlled atmosphere to achieve a metallurgical bond between the tungsten and copper particles. The sintering process helps achieve the density and strength required for alloy plates. Infiltration: The sintered tungsten billet is then subjected to a copper infiltration process. This involves placing sintered tungsten briquettes into a furnace containing molten copper. The high temperatures cause the copper to melt and penetrate into the porous structure of the sintered tungsten, creating a composite material that combines the properties of both tungsten and copper. Final processing: Once infiltration is complete, the composite is further processed to achieve final dimensions, surface finish and any required post-processing (such as heat treatment or machining) to meet specific tolerances and requirements. The production method of tungsten-copper alloy plates requires careful control of the powder mixing, compaction, sintering and infiltration processes to achieve the desired properties and quality of the final product. Additionally, the specific details of the production method may vary depending on the manufacturer and the intended application of the tungsten copper alloy plate.
