2.7mm AWS A5.21 ERCoCr-A Cobalt-based Surfacing Welding Wire Price
Product Description:
EB cobalt alloy's™ 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 alloys are selected for their excellent resistance to the widest combination of wear types including adhesive wear, abrasion, erosion, contact fatigue, thermal shock, cavitation wear, corrosion and oxidation. The degree to which the cobalt alloys retain these properties assures their unique position in the wear technology field.
AWS RCoCr-C (cobalt alloy 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 RCoCr-A () 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 RCoCr-B (cobalt alloy 12) It has
excellent resistance on high heat, corrosion and abrasion.
Recommended use for making high-pressure valve, shear edge,
sawteeth, etc. AWS RCoCr-B (cobalt alloy 21) It has excellent
resistance on high heat, corrosion and abrasion. Recommended use
for making fuild valve,brass casting die , vlave seat, etc.
