Eutalloy® 10681

Ni-B-Si nickel-base fusible alloy designed for build-up on metals including steel, stainless steel, cast iron and nickel alloys.

Eutalloy 10681 is a premium nickel base alloy powder designed to provide optimum and easy build-up on steel, cast iron, stainless steel, nickel and nickel alloy parts with excellent machinability. It has great success in buildup on edges and corners with no sagging or running and crack free. Machined deposits are bright and porosity free. The hardness of this alloy promotes good edge integrity while not detracting from its machinability. The high compressive strength of this alloy resists deformation at elevated temperatures. Deposits will not scale even at elevated temperatures. The Eutalloy process permits precise deposition with a minimal amount of overspray. Thin, tough overlays can be applied and dimensional tolerances maintained. Coatings have exceptional build-up capability. Finish by machining.

Used for dimensional buildup. It has been most successful in the build-up of corners on keyways, shoulders on shafts, bosses on steel castings.
