Magnetic nickel base ternary brazing material and method of application

摘要

A ternary magnetic braze alloy and method for applying the braze alloy in areas having limited access. The magnetic braze alloy is a nickel-based braze alloy from the perminvar region of the Ni, Fe, Co phase diagram. The braze alloy includes, by weight percent 8-45% Fe, 0-78% Co, 2.0-4.0% of an element selected from the group consisting of B and Si and combinations thereof, and the balance Ni. The nickel-based braze alloy is characterized by a brazing temperature in the range of 1850-2100° F. The nickel-based braze alloy is magnetic below its Curie temperature.
