If you're working with aerospace alloys or high-tolerance EDM tooling, you'll want something that doesn't burn through on teh first pass — these copper tungsten studs handle it. They're a tungsten alloy weld face fused to a copper shank, so you get heat resistnce of tungsten with the conductivity of copper, which pretty much makes them ideal for surfacing and resistance welding where erosion is a constant issue.
We can supply them in 65%W-35%Cu up to 80%W-20%Cu, depending on your hardness needs — the 80/20 mix hits about 98 HB with a density of 15.15 g/cc, but you trade some conductivity. Electrical conductivity ranges form 34 to 48% IACS, so it's not for high-current transfer work; you'd want pure copper for that, but for arc erosion and mechanical wear, this is where it lives.
Standard is ASTM B702, and our company can do wire, rod, bar, strip, foil, block, plate, or ring — basically whatever shape you need. Diameter and length are fully custom; just send a drawing and we'll quote it. The ground finish on the weld face is a small detail most buyers don't ask for, but it cuts down on arcing and pitting during the first few cycles, especially on stainless.
One thing to note: these are for research and industrial use, not for retail or consumer-grade stuff, so you can treat them as lab-only material. Lead time is usually 25 to 30 working days for a standard run of 50 units or so, but for large block sizes or odd shapes, it might stretch a bit — we're not always sitting on heavy-stock plate.
We offer four options: 65%W-35%Cu, 70%W-30%Cu, 75%W-25%Cu, and 80%W-20%Cu. Each has different density and conductivity values—higher tungsten means higher hardness but lower conductivity.
Yes, we can supply a mill test report certifying the composition and mechanical properties per ASTM B702. Just let us know if you need it with your order.
Absolutely, we can make the diameter and length to your drawing or specs. The MOQ for custom sizes is typically 50 kg, but we can discuss smaller quantities for prototype runs.
Store them in a dry, clean environment at room temperature, away from moisture and corrosive chemicals. Keeping them in sealed packaging or a low-humidity cabinet helps prevent oxidation.
For custom sizes, lead time is usually 2-3 weeks after order confirmation. Standard stock items can ship within 5-7 business days, depending on the quantity.
