Phosphorus copper is a type of alloy that has three special properties. It is used to improve the electrical conductivity and strength of various products. In addition, it helps to make brazing rods melt at lower temperatures.
The global copper phosphorus alloy market was valued at USD 275.9 million in 2021. However, it was projected to reach USD 379.7 million by the end of 2028. During the forecast period, the market has projected to experience a 4.7% CAGR.
Among the segments of the copper phosphorus alloy market, CuP8 is the leading segment. This alloy is widely used in the air conditioning industry, refrigerators, and railways.
This alloy has a brittle form. As a result, it is difficult to cast it into an ingot. Therefore, its application range is limited. Consequently, the demand for this alloy is relatively low.
Besides its corrosion resistance, phosphor copper adds hardness and elasticity to alloys. Also, it can strengthen and deoxidize copper. These characteristics make it suitable for use in products such as radiators, air conditioners, and heater elements.
Phosphorus copper is commonly mixed with other metals, such as aluminum. It can also be used in decorative plating.
In general, the phosphorus content of the alloy can range from eight percent to twenty-three percent. Copper with a phosphorous content of more than eight-and-a-half percent is difficult to form. However, the cost of manufacturing is higher.
Because of its deoxidizing effects, phosphorus copper has applications in several industries. A few examples are oil lines, heater elements, and electrical connectors.
