The ECOCR-E welding electrodes are primarily made up of cobalt (about 60%), chromium (25–30%), and tungsten (4–6%), along with trace amounts of carbon, silicon, and nickel. This unique blend offers outstanding resistance to abrasion, metal-to-metal wear, and oxidation at elevated temperatures. The weld metal produced typically reaches a hardness of 40–45 HRC, showcasing excellent toughness and crack resistance. ECOCR-E electrodes guarantee a stable arc, minimal spatter, and robust metallurgical bonding, ensuring mechanical integrity in high-stress, high-heat applications while also providing impressive durability against thermal cycling.
