The phos-copper 15% is one specific alloy containing 85% copper, and 15% phosphorus. Besides its distinguishable properties, it is widely used in welding and brazing processes. Phosphor bronze or the copper tin alloys contain this substance in a proportion of about fifteen percent. It is however important to note that other phosphoric bronzes may have different amounts of these two elements combined together; therefore, it cannot be generalized to all phosphoric bronzes. The phos copper solder alloy has good flow ability for contact brazing, flame brazing, high frequency induction brazing and furnace brazing. This will confer on the new amalgam the wetability potential of solders besides bringing down melting point and enhance strength as well as toughness. It is extensively used in the refrigeration trade and motor industry, electrical appliances industries, instrumentation manufacturing industries etc. For instance, copper zinc solder works best when using flame or resistance or even high frequency methods of brazing . If you want to know more about these materials and where they can be used then you might need to approach any China 15% Phosphorus Copper Manufacturer who will give you a clear picture on what they are all about.

Adding silver to phosphor copper alloys significantly improves the wetting ability of the solder, increases its strength and toughness, and lowers its melting point. This improves the overall performance of the brazing process.
Phosphorus copper solder has a wide range of applications and is commonly used in ordinary flame welding. It is mainly used in the refrigeration, air conditioning, plumbing and electrical industries. We can produce all kinds of formulas, and can also cooperate with R&D and customization to reduce costs and increase efficiency for your production. Specifically Please contact the technical department if required.
Phosphorus acts as a deoxidizer, reducing oxide formation during brazing. This improves the fluidity and flow of the solder, ensuring cleaner, stronger joints.
The alloy is suitable for a variety of brazing methods, including:
Contact brazing
Flame brazing
High frequency brazing
Furnace brazing
The phosphorus content in the alloy generally reduces the need for additional flux during brazing, thus simplifying the procedure and reducing costs.
While 15% phosphor copper is well suited for brazing copper and its alloys, copper-zinc solder is primarily used in flame, high frequency induction heating, and resistance brazing methods. Copper-zinc solder is often selected for its specific properties that make it suitable for these applications.
Refrigeration industry
Motor manufacturing
Electrical appliances
Instrument manufacturing
Other manufacturing industries involving copper and its alloys
While there are no strict storage requirements, it is recommended that the alloy be stored in a cool, dry place to prevent any potential oxidation or contamination that could affect its brazing properties.
