Designed for high temperature brazing. Please consult our sales engineer for further details.
High Temperature Copper Base
|Product||Normal Composition||Melting Range ºC||Commments|
|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:Mn: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.|
When brazing with the Bronzes, Tenacity 125,300 or 500 are recommended, with Tenacity 125 being the general purpose flux. 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.
