Home > Copper Tungsten 80/20 Rod
Elvis Nickel Alloys, a well-respected manufacturer and supplier located in Houston, USA, specializes in high-performance Copper Tungsten 80/20 Rods. These rods beautifully blend the excellent thermal and electrical conductivity of copper with the impressive melting point and strength of tungsten. Made up of 80% copper and 20% tungsten, they are crafted using powder metallurgy, ensuring remarkable uniformity and durability. Perfect for applications that require outstanding thermal resistance, wear resistance, and electrical conductivity, these rods are commonly found in electrical contacts, resistance welding electrodes, and heat sinks. They deliver reliable performance even in high-stress and high-temperature settings, making them essential in aerospace, defense, and electrical industries.
Copper Tungsten 80/20 Rods consist of about 80% copper and 20% tungsten, merging the thermal conductivity of copper (around 200–300 W/m·K) with the high melting point and wear resistance of tungsten (approximately 3420°C). These rods boast excellent density (around 11.85 g/cm³), hardness, and moderate tensile strength (roughly 415–500 MPa). This unique blend provides high arc resistance, dimensional stability during thermal cycling, and strong resistance to deformation and erosion. With the right tooling, they are also quite machinable and maintain their performance integrity even under extreme electrical or thermal loads.
