APPLICATIONS

DULLFOS® alloy is a phosphor copper alloy with silver, which has good filling and capillarity characteristics. It is widely used in the production of heating, air conditioning, refrigeration, heat exchangers, mechanical equipment, electric motors, winding transformers. Production and repair of household appliances. For plumbing, for copper pipes for hot and cold water, construction and installation of copper gutters. In copper-copper unions it can be used without the use of deoxidizer, the use of which is also required in brazing copper-brass/bronze joints. Do not use in a sulphur-containing environment with Fe and Ni alloys. For heating, air conditioning, refrigeration, heat exchangers, mechanical equipment, electric motors, winding transformers.
