CORODUR® SP 120

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 5 – 1,6 - 4

MATERIAL REVIEW:

Fair resistant to corrosion but hard wire alloy having good wear resistance. Low shrinkage allows relative thick coatings. Good machinability by grinding. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.

APPLICATION

Used for repair and upgrade of machine components, plunger, bearings, rolls.
