Frequently Asked Questions (FAQ)
Q
What are the primary performance advantages of Tungsten Copper (WCu) alloys?
Tungsten Copper alloy combines the high density, high melting point, and low thermal expansion of tungsten with the exceptional thermal and electrical conductivity of copper. This makes it highly resistant to arc erosion and thermal shock.
Q
How does the copper content affect the properties of WCu alloys?
Higher copper content (e.g., CuW50) enhances electrical and thermal conductivity, whereas higher tungsten content (e.g., CuW90) significantly increases density, hardness, transverse rupture strength (TRS), and arc ablation resistance.
Q
What standard product forms and shapes are available?
We provide heat sinks, heat spreaders, baseplates, bars, rods, tubes, bricks, ultra-thin sheets, wires, and customized precision-machined electrical and military components tailored to exact drawings.
Q
What typical industries utilize customized tungsten copper composites?
WCu alloys are widely utilized in power semiconductors, thermal management substrates, high-voltage electrical contacts, EDM electrodes, resistance welding, and aerospace/military high-temperature components.
Q
Can Zhuzhou Jiuding Metal Technology supply non-standard specifications?
Yes. Beyond our standard CuW(50) to CuW(90) material grades, we offer full custom manufacturing solutions including tight-tolerance machining, custom composition ratios, and specialized surface finishes.
