Product description
Cobalt base alloys are available as cobalt rods, cobalt electrodes, cobalt wire and cobalt powder. Cobalt alloys are used primarily for wear applications, our cobalt alloys can be applied by any known fusion welding process or HVOF spraying proess and are particularly well-suited for hardfacing applications. Cobalt alloys are the most widely used wear resistant hardfacing materials available. Their unique combination of wear resistance, strength and corrosion resistance make them adaptable to many harsh environments.
Cobalt Base Alloy Bare Welding Rods
- AWS ECoCr-C (Stellite 1)

AWS ECoCr-C (Stellite 1)
It has excellent wear and heat resistance at high temperature.
Recommended use for making valve seal inserts , rotating sealing ring, drill heads, cutter edge ,etc
AWS ECoCr-A (Stellite 6)
The most widely used Cobalt Alloy with good mechanical
properties at different temperatures, Recommended use
for making valve seat material, hot shear blade, high temperature valve , turbine blade ,etc.
AWS ECoCr-B (Stellite 12)
It has excellent resistance on high heat, corrosion
and abrasion. Recommended use for making high-
pressure valve, shear edge, sawteeth, etc.
AWS ECoCr-E (Stellite 21)
It has excellent resistance on high heat, corrosion
and abrasion. Recommended use for making fuild valve,
brass casting die , vlave seat, etc.
