These stud electrodes are manufactured using RWMA Class 2 material, featuring a 10W (copper tungsten) weld face that ensures extended service life. Designed with wrench flats for effortless removal from holders, the insulator is built to endure constant friction during insertion and extraction processes. The copper tungsten components undergo a ground finish and are produced through pressing and sintering methods, resulting in products such as copper tungsten electrical contacts, electrodes, rods, and more for various industrial uses.
Available in multiple compositions including 65%W-35%Cu, 70%W-30%Cu, 75%W-25%Cu, and 80%W-20%Cu, these electrodes adhere to the ASTM B702 standard, guaranteeing high quality and performance. They exhibit low thermal expansion, high wear resistance, minimal consumption, excellent arc resistance, and superior thermal and electrical conductivity.
Applications span across Walter and Vollmer machines for electrical contacts, spark erosion (EDM) processes, aerospace components, medical devices, oil and gas sectors, and high-tech fields. Copper tungsten alloy is preferred for products requiring high heat resistance, low thermal expansion, and efficient conductivity, making it suitable for engines, electrical devices, refractory parts, heat sinks, rocket components, and switches.
In EDM applications, copper tungsten electrodes outperform graphite due to their high melting point, leading to longer service life and enabling the production of smaller diameter rods and tubes with reduced risk of chipping and warping. This material is also fabricated into sheet metal, tubing, and plate metal for diverse industrial needs.
All products undergo rigorous testing for density, tensile strength, yield strength, conductivity, elongation, and hardness to ensure they meet specified requirements. This copper tungsten alloy is supplied for research use only and not for personal applications.
