Brazetec Filler Metals for Brazing Without Cadmium

The silver brazing filler metals listed on this page can be used directly for service temperatures of - 200 to + 200 ° C as a general rule. They are suitable for all types of steel, copper, copper alloys, nickel and nickel alloys.

BrazeTec Comet - High-Carb Casting Sticks, Cadmium-Free

BrazeTec's extensive range of cadmium-free braze solders also include BrazeTec coated CoMet rods (Coated Metal). The flux used for the coating is FH 10 type according to DIN EN 1045 and is free of boric acid. Please refer to the indications on solder fillings for the coated rods. Due to the coating, the silver content of these rods is lower than that of bare solder rods. The composition of the rods themselves (without the coating) obviously corresponds to the composition specified for the brazing metals without cadmium.

BrazeTec Cupro-Phosphorus Supply Metals for Brazing Copper

These products are suitable for service temperatures between -70 and + 150 ° C. The cuprophosphorus filler metals listed on this page have been specially designed for assembling copper or copper alloy parts (brass, bronze, red brass). Flux use is not required for brazing two copper parts with these filler metals given their phosphorus content. Neither are they suitable for (Fe) steels or nickel alloys because of a brittle phase. BrazeTec S2 and BrazeTec S94 filler metals are authorized (DVGW, the German Association of Water and Gas Experts) for the installation of copper pipes.

BrazeTec BrazeTec BrazeTec Special Applications Supply Metals..

BrazeTec 7200 and BrazeTec 6009 filler metals can be used for both air soldering with flux addition and for furnace brazing in a protective atmosphere without flux. BrazeTec 6009 is used with BrazeTec flux spezial h for brazing special steels. For use under vacuum, a brazing temperature of 900 ° C should not be exceeded in order to avoid the volatilization of silver. The brazing temperature depends on the base metals.

Brazetec Multilayer Filler Metals for Soldering Hard Metals

For soldering hard metals, BrazeTec has developed special multilayer filler metals that can compensate for internal stress caused by differences in thermal expansion coefficient. For complex applications requiring very high shear strengths, BrazeTec recommends the BrazeTec 49 / Cuplus filler. The final strength of the brazed joint is conditioned by the strength of the base metal.

Brazetec Filler Metals for Soldering Hard Metals

The specified filler metals are suitable for soldering hard metals and hard-to-wettable materials, such as tungsten, molybdenum, tantalum or chromium. The final strength of the brazed joint is conditioned by the strength of the base metal.

Brazetec Auxiliary Metals for Active Soldering of Ceramics

BrazeTec filler metals for soldering require a brazing temperature of at least 850 ° C to allow the assembly of ceramics. Higher temperatures may improve wetting. Brazing is carried out under pure argon (4.8) or under vacuum (<10-3 mbar). For use under vacuum, a brazing temperature of 900 - 1000 ° C should not be exceeded in order to avoid the volatilization of silver.

Brazetec Supply Metals for Aluminim Brazing

In general, BrazeTec solid solders and pastes for aluminum brazing can be used for both open-air brazing and protective atmosphere brazing.

Brazetec Flux for Brazing Strong

The choice of flow depends on the working temperature of the filler metal and the base metals. The working temperature or the melting range of the filler metal must be within the active temperature range of the flux. As a general rule, flows are supplied in the form of paste. Some types, however, also exist in powder form. For particular applications, the required flow can be manufactured on demand.

Brazetec Anitflux Paste

BrazeTec Antiflux ASV prevents the wetting of the filler metal on surfaces that must not be wet and thus allows very precise soldering.
