Cadmium-Free silver brazing alloys are used for the joining of most ferrous and nonferrous metals, except aluminum and magnesium. Silver alloys are low-temperature, free-flowing, and produce strong, ductile, and leak-proof braze joints.
Silverphos
Silverphos alloys are used extensively in the HVAC/R industry. They are commonly employed for brazing copper pipes, fittings, and components in air conditioning systems, heat exchangers, refrigeration units, and other cooling equipment. The alloys provide strong and leak-tight joints, ensuring efficient heat transfer and refrigerant containment.
In plumbing and pipework systems, these alloys are employed for joining copper pipes, valves, and fittings. The alloys offer excellent fluid-tight joints, preventing leaks and ensuring the integrity of the system.
