Tungsten Copper Rod Manufacturers: 7 Proven Tips to Choose the Right One
Choosing among Tungsten Copper Rod Manufacturers isn't always about price. A rod that looks perfect on the quote may fail prematurely if the tungsten-to-copper ratio, density, or conductivity isn't right for your duty cycle. This guide will show you 7 practical tests to perform before ordering. Use them whether you buy for EDM electrodes, resistance welding, circuit breaker contacts, or heat sinks. Key Takeaways Match the tungsten-copper ratio to your application first, then compare suppliers. Ask for measured density, conductivity, and hardness on your own batch, not catalog figures. Check ASTM B702 alignment and request a 3.1 test certificate. Confirm batch traceability, size range and machining support. Order a sample lot before committing to bulk volumes. What Tungsten Copper Rods Do and Why Supplier Choice Matters Tungsten copper (WCu or CuW) combines two metals that do not dissolve in each other. This results in a composite rather than a true alloy.
