Q What product forms and components do you supply?
We manufacture and supply heat sinks, heat spreaders, heat bases, electrical contacts, military components, bars, rods, tubes, bricks, ultra-thin sheets, and wires.
Q Can tungsten copper alloy products be customized?
Yes, Zhuzhou Jiuding Metal Technology Co., Ltd. can manufacture custom tungsten copper alloys tailored to specific industrial dimensions, compositions, and technical specifications.
Q Why is WCu alloy widely used for heat sinks and thermal management?
Its tailored thermal expansion coefficient matches semiconductor substrates closely while maintaining high thermal conductivity, effectively preventing thermal fatigue and overheating in high-power electronic devices.
Q How does the tungsten content influence alloy hardness and conductivity?
Higher tungsten content increases alloy density, hardness (up to 260 HB for CuW90), and tensile strength, while higher copper content enhances electrical conductivity (% IACS) and thermal dissipation.
