Aleación de cobre y wolframio
Tungsten Copper Alloy is produced by powder metallurgy, containing 6%-50% copper. Its properties depend mainly on its composition. Alloys with less copper content have higher density, hardness, and resistivity. HM provides high-precision tungsten copper alloy products in various forms, including rods, plates, sheets, bars, tubes, blocks, pellets, wires, and discs, all crafted to ensure exceptional quality and customer satisfaction. We manufacture large, complex parts using isostatic pressure molding technology, while smaller parts are produced through extrusion, molding, and injection molding techniques. Additionally, rods and sheets are fabricated using forging and rolling processes.

Tungsten Copper Alloy Production Process
Tungsten-copper alloy is produced using powder metallurgy. A key manufacturing process for this alloy is infiltration: after compacting the porous tungsten preform, copper is allowed to infiltrate it, followed by sintering. The material is then machined to achieve the required geometry as specified by the customer. Tungsten-copper alloy is a pseudo-alloy of copper and the refractory metal tungsten. Since copper and tungsten are immiscible, the infiltration method is used to achieve bonding between the two materials. The specific processes are as follows:
- Compaction: The porous tungsten preform is compacted.
- Infiltration: Copper is allowed to infiltrate the compacted tungsten preform.
- Sinterización: The infiltrated material is sintered at high temperatures, forming a dense solid material.
- Recocido: Los productos sinterizados se someten a un proceso de recocido para eliminar las tensiones internas y mejorar la tenacidad y la ductilidad.
- Mecanizado: Los procesos de mecanizado de precisión, como el torneado, el fresado y el rectificado, se aplican a las piezas sinterizadas para conseguir las dimensiones y formas finales.
- Tratamiento térmico: La aleación se somete a un tratamiento térmico adicional para optimizar propiedades como la dureza, la resistencia u otras características físicas.
- Tratamiento de superficies: Si es necesario, se aplican tratamientos superficiales (como revestimiento, pasivado, etc.) para mejorar la resistencia a la corrosión, la dureza u otras propiedades.
