COPPER PHOSPHORUS ALLOYS WITHOUT SILVER

They are alloys composed of copper phosphorus with different characteristics and self-stripping in copper / copper brazing. This property gives them the possibility to eliminate the need to apply paint stripper during the application process.
Its application is particularly recommended in the refrigeration and plumbing sectors when applying copper / copper pipes to sanitary circuits, or central heating, etc.
It is not recommended to use nickel or iron based materials because the welding joint becomes brittle.
All references can be produced in rod, wire, preformed, and some can also be produced in laminated belt form.
