FCW K650
Seamless high fill copper coated tubular wire for semi-automatic gas shielded hardfacing
Description & applications
•Seamless high fill copper coated tubular wire for semi-automatic gas shielded hardfacing
•Unique welder appeal
•Deposition rate increased by up to 20% when compared to solid wire
•Martensitic weld metal contains finely dispersed hard carbides ensuring an optimal balance between abrasion, friction and impact resistance
•Wire does not pick up moisture, the wire feeding properties are excellent
•Designed for welding in horizontal, horizontal-vertical and vertical-up positions •Abrasion resistance is maintained at service temperatures up to 500°C
APPLICATIONS
FCW K650 is used for hardsurfacing components that must combine resistance both to abrasion and to moderate impact
Examples
Bucket teeth, bucket lips, bulldozer blades, crusher jaws, scraper blades, chutes, pump housings, conveyor screws, slide plates, gear teeth, crusher hammers, drilling bits, ploughshares, dies, impact drills etc.
