Brazing Alloys for Tungsten Carbide
|Product||Normal Composition||Melting Range ºC||Comments|
|F-Bronze||57.5% Cu:Zn:Mn:Co||890-930||Recommended for brazing cemented carbide into rock drills and similar percussively loaded joints. The group offers a range of brazing characteristics to match different material and heat-treatment requirements. ‘F’ Bronze is
covered by S.A. Patent 75/0487.
|D-Bronze||86% Cu:Zn:Co||980-1030||Recommended for brazing cemented carbide into rockdrills and similar percussively loaded joints. For brazing in air use Tenacity 125 flux.|
|DB Alloy||48%Cu: Zn: Ni||920-935||Low cost alloy ideal for use on tubular steel, furniture and display racks. The alloys high strength makes it particularly suitable for butt joints. Also used as an infiltrant in the manufacture of rock drills. DB Alloy also work-hardens and is used for re-building of gear teeth.|
|DB 2 Alloy||45%Cu: Zn: Ni: Fe: Ag||880-960||For infiltration brazing in diamond core drills.|
|HT Bronze||55%Cu:Zn:Mn:Ni:Si||880-920||Suitable for applications involving moderately elevated service temperatures. Produces high strength joints on ferrous materials and cemented carbides. Primarily used for joining tungsten carbide to steel. Brazing is often combined with heat treatment.|
|Easy-flo 1||50%Ag: Cu:Zn:Cd||620-630||General purpose cadmium bearing alloy with excellent mechanical properties.|
|Easy-flo 2||42%Ag: Cu:Zn:Cd||608-617|
|Easy-flo 3||50%Ag: Cu:Zn:Cd:Ni||634-656||Preferred Cadmium bearing alloy for joining tungsten carbide.|
|Argo-braze 49 H||40%Ag: Cu:Zn:Ni:Mn||680-705||Cadmium free alternative to Easy-flo 3. Presence of Manganese enhances wetting on difficult carbides.|
When brazing with the Bronzes, Tenacity 125,300 or 500 are recommended, with Tenacity 125 being the general purpose flux. Use Easy-flo flux with Easy-flo 1,2 and 3 alloys. When brazing with Argo-braze 49H, the flux is dependent on the application. Please consult Probraze Metals for your specific application.
Custom Bronzes are available
