Oerlikon Fluxofil 50 description: FLUXOFIL 50 ia a seamless copper coated basic flux cored wire for the hardfacing of wear components subjected to heavy impact such as pulleys, rollers, caterpillar track rollers, sprockets, track links, etc. The weld metal is of medium hardness and machinable by chip-forming. Flame and inductive hardening are feasible. Before depositing the final pass, the interpass temperature should not exceed 250C. Due to the very tough and crack-resistant weld metal, a buffer layer is not normally necessary.
