The ECOCR-C Welding Electrodes are engineered to produce a hard, wear-resistant deposit that maintains its strength and surface integrity even at elevated temperatures. With a typical hardness of around 55–60 HRC, these cobalt-based electrodes are particularly suitable for hardfacing components exposed to severe abrasion, impact, and high thermal stress. Industries such as aerospace, power generation, chemical processing, and mining rely on Metals And Welding Specialities’ ECOCR-C electrodes for their consistent welding performance and long-lasting protection against wear and corrosion.


This alloy’s unique composition includes cobalt, chromium, and tungsten, which together provide remarkable resistance to oxidation and scaling up to approximately 1100°C. The high chromium content forms a protective film on the surface, ensuring excellent resistance to hot gases and oxidizing environments. Meanwhile, the tungsten improves hardness and mechanical strength, making Cobalt Base Alloys ECOCR-C Electrodes the preferred choice for surfacing valve seats, turbine blades, hot shear blades, and forging dies.

Metals And Welding Specialities produces these electrodes with precision to ensure smooth arc stability, minimal spatter, and superior weld deposit quality. The electrodes are ideal for both manual and automated welding operations, delivering consistent results across a range of base metals. Whether you are rebuilding worn parts or fabricating components that require extreme wear and corrosion protection, Metals And Welding Specialities ECOCR-C Welding Electrodes provide unmatched reliability and cost efficiency.

All products are manufactured under strict quality control standards to meet the specifications of ASTM CoCr-C and UNS R30006. Metals And Welding Specialities ensures every batch undergoes rigorous testing to guarantee mechanical strength, chemical composition, and metallurgical integrity. The result is a cobalt-based electrode that exceeds industry expectations for performance and durability.

With decades of metallurgical expertise, Metals And Welding Specialities continues to be a leading supplier of cobalt base alloy welding electrodes trusted by engineers and fabricators worldwide. Our commitment to quality, innovation, and customer satisfaction makes us the go-to source for specialized welding consumables that perform under pressure and extend component life.
