5283 RB Brazing alloy based on copper-silver-phosphorus

5283 RB, Ø 2.0mm / 1.0kg

Bright ingot with 15% silver content,

Ideal for joints exposed to vibration, cooling, air conditioning, If you want to improve the quality and smoothness of soldering, I recommend the use of CU Flux 5000FX - flux is not required.

Properties
Low-viscosity, overheating-resistant brazing alloy based on copper-silver-phosphorus with a high degree of purity. Very smooth melting behavior.
Narrow melting interval and low soldering temperature. Very good flow properties, excellent wetting properties. High strength
strength and elongation. Smooth, dense and pore-free seams. The solder has a deoxidizing effect on copper, so no flux is required.
Permissible operating temperatures up to 150 °C. Cold-resistant down to approx. - 70 °C.

Applications
For gap soldering, also in series production, e.g: Copper (SF-Cu), gunmetal, bronze (CuSn alloys), brass (CuZn alloys), nickel silver (CuNiZn alloys), Al-bronze (CuAl alloys).
For joining thin-walled workpieces and those with different wall thicknesses.
wall thicknesses.
Typical applications are
Rotors of electric motors, pipe connections, pipe coils, copper connections of cooling systems, sanitary systems, apparatus for air conditioning systems, heating installations.
Not to be used with media containing sulphur or on iron or nickel alloys.

Processing instructions
Clean soldering areas. Round off edges. Coat soldering surfaces with flux. Heat the tip of the soldering rod and dip it into the flux. Preheat the workpiece widely and continuously. Do not overheat. Corrosive flux residues.

Heat sources
Flame soldering, furnace, induction and resistance heating, TIG.
