Special silver alloys for tungsten carbide
Special silver brazing alloys are suitable for brazing materials which are difficult to wet, such as stainless steel, tungsten, chromium, molybdenum and tantalum. They are usually used in the tool industry.
The group Ag49MnNi, Ag40Ni and Ag27Mn are cadmium free alloys containing nickel and manganese. The nickel improves wetting on carbides and produces a less free flowing alloy. The manganese content improves the wetting on carbides containing titanium and tantalum which are difficult to wet under normal brazing conditions. The use is limited only by relatively high temperature of melting.
L-Ag49MnNi/Cu is the compound alloy (triple metal sheets—trifoil) with an interconnected layer of copper which absorbs crashes and vibrations and has low melting point.
