ECoCr-B (Cobalt 12) Cobalt Hardfacing & Wear-resistant Welding Electrode Alloy Type: A5.13, SOLID SURFACING Electrodes and Welding Rods, A5.13 ECoCr-B Cobalt Alloy 12 could be considered an intermediate alloy between Cobalt Alloy 6 and Cobalt Alloy 1.  It contains a higher fraction of hard, brittle carbides than Cobalt Alloy 6, and has increased resistance to low-angle erosion, abrasion, and severe sliding wear while retaining reasonable impact and cavitation resistance.  Cobalt Alloy 12 is often used self-mated or running against Cobalt Alloy 6 or 1.  The higher tungsten content provides better high-temperature properties compared to Cobalt Alloy 6, and it can be used at temperatures up to about 700⁰C.  Cobalt Alloy 12 is typically used for cutting tools that need to withstand abrasion, heat and corrosion. Typical Applications:   chain saw bars; saw teeth; extrusion dies
