    Custom Made Copper Tungsten Alloy , 75W25Cu Class Submerged Arc Welding Contact Tips

    WCu Copper Copper Tungsten Alloy Submerged arc welding contact tips with 75W25Cu

    Submerged arc welding contact tips:

    Generally contact tips was made of copper or the (chromium zirconium copper). Currently, most of the big vessels and big diameter oil pipe need be welded by automation welding machine, which means it need complete the welding process without the stop. Those process controls ensure the welding as good quality. CuCrZr contact tips soft temperature around 800ºC, its less wear resistance capability can not guarantee the 24 hours welding system keep welding without stop to replace the tips.

    JBNR develop the new technology of SAW welding contact tips by using copper tungsten to keep higher softer temperature, higher wear resistance, and CuCrZr material which keep good thermal conductivity.

    Our customers are using our contact tips and proved our product have very good quality. They feedback our new contact tips’ life time is at least 5 times longer than the Cu and CuCrZr.


    They are extensively used as thermal mounting plates, chip carriers, tungsten copper flanges, and frames for RF, light emitting diodes and detectors, laser diode packages like pulse, single emitter, bars and complex carriers for optoelectronics amplifiers, receivers, transmitters, tunable lasers, etc.
