The difference between brass and white copper use:
1, the composition is different. Brass is composed of copper and zinc alloy. If it is only composed of copper and zinc brass is called ordinary brass. If it is composed of more than two elements of a variety of alloys is called special brass. White brass is a copper-based alloy with nickel as the main added element.
2, different physical properties. Special brass high strength, hardness, chemical corrosion resistance. There are also cutting mechanical properties are more prominent. There are also cutting mechanical properties are more prominent. White copper is silver-white, with a metallic luster, so the name white copper. White copper than other copper alloy mechanical properties, physical properties are exceptionally good, good ductility, high hardness, beautiful color, corrosion resistance, rich deep-drawn performance.
3, the use of different occasions (different uses). Seamless brass tubes can be used for heat exchangers and condensers, low-temperature piping, submarine transportation tubes. Manufacturing plate, strip, bar, pipe, casting parts and so on. Widely used in shipbuilding, petrochemical, electrical appliances, instrumentation, medical equipment, daily necessities, handicrafts and other fields. It is also an important resistance and thermocouple alloy.

The advantages and disadvantages of white copper:
Pure copper with nickel can significantly improve the strength, corrosion resistance, hardness, resistance and thermoelectricity, and to reduce the resistivity temperature coefficient. Therefore, white copper than other copper alloy mechanical properties, physical properties are exceptionally good. And also important resistance and thermocouple alloy. The disadvantage of white copper is the main added element - nickel belongs to the scarce strategic materials, the price is more expensive.
Brass advantages and disadvantages:
Brass is composed of copper and zinc alloy, composed of copper, zinc brass is called ordinary brass, if it is composed of more than two elements of a variety of alloys is called special brass. Brass has strong wear resistance, brass is often used in the manufacture of valves, water pipes, air conditioning inside and outside the machine connecting pipes and radiators.
