BRASS ALLOYS
BRASS ALLOYS
Copper-zinc alloys with additional enrichment of elements like: silicon, tin, manganese, nickel or cobalt are used for joining carbon steel, cooper and its alloys in the tool industry for brazing cemented carbide plates. They have good mechanical properties but in a case of high temperature of melting point and a relatively low fluidity their use is limited. Inconnection with the liquid flux technology is possible to eliminate the traditional fluxes in paste or powder forms.
