Harris Products Group, 40N518L, Silver Brazing Alloy, Cadmium-Free; 2% Nickel Addition; Improved Corrosion Resistance

Safety-Silv® 40Ni2 silver brazing filler metal is engineered for brazing copper, brass, steel, nickel alloys, and stainless steel. This alloy typically exhibits improved corrosion resistance on stainless steel compared to brazing alloys without the nickel addition. The 2% nickel addition improves wetting and strength. Safety-Silv® 40Ni2 exhibits a wider melting range with a slightly elevated melting temperature. It is frequently used to braze tungsten carbide to steel and tool steel for cutting tips, drill bits, and saw blades. Applications are similar to those of the higher silver Safety-Silv® 50N, but Safety-Silv® 40Ni2 exhibits a wider melting range with a slightly elevated melting temperature. Conforms to the EU Reach & RoHS directive.
