Tungsten Copper Composite (W-Cu Composite) CuW75 FAQs

Q1: What are the key material properties of Tungsten Copper Composite (W-Cu Composite) CuW75?

A1: CuW75 typically contains 75% tungsten and 25% copper by weight. This balance results in thermal conductivity (typically 170–200 W/mK) and moderate electrical conductivity. Additionally, it offers high density, good machinability, and a coefficient of thermal expansion close to steel, making it ideal for heat sink and electrode applications. The composite also retains tungsten’s mechanical strength while leveraging copper’s ductility for improved toughness.

Q2: How can this product be processed or fabricated?

A2: CuW75 can be produced using powder metallurgy techniques involving high-purity tungsten and copper powders. These powders are mixed, compacted, and sintered under controlled temperatures to obtain a preform. An infiltration step follows, where molten copper is introduced to fill open pores, enhancing densification. Subsequent operations may include precision machining or hot forging to achieve the desired geometry and surface finish.

Q3: Which quality standards and certifications apply to Tungsten Copper Composite (W-Cu Composite) CuW75?

A3: Manufacturers of CuW75 typically adhere to recognised quality standards such as ISO 9001 for quality management and ISO 14001 for environmental practices. Industry-specific guidelines, including ASTM B702 for tungsten copper composite materials, also ensure consistent composition and mechanical properties. Additional certifications, such as AS9100 for aerospace or RoHS compliance, may apply depending on the intended application and regional requirements.
