Safety-Silv® 40Ni2 Brazing Alloy HARRIS

Safety-Silv® 40Ni2 brazing filler metal is engineered for brazing copper, brass, steel, stainless steel, and nickel-based alloys. The addition of 2% nickel improves alloy wetting behavior and joint strength while enhancing corrosion resistance, particularly when joining stainless steel components.

This alloy serves applications similar to higher silver content alloys such as Safety-Silv® 50N, but it features a wider melting range with a slightly higher operating temperature. It is commonly used in demanding industrial work such as brazing tungsten carbide to steel and tool steel components including cutting tips, drill bits, and saw blades.

The alloy is available in multiple product forms, including clad strip options, to support varied manufacturing and assembly requirements.
