| Product Introduction | ||||||||||||
| Zinc white copper has excellent comprehensive mechanical properties, excellent corrosion resistance, good cold and hot processing formability, and is easy to cut. It can be made into wire, bar and plate, and used to manufacture precision parts in the fields of instruments, meters, medical devices, daily necessities and communications. | ||||||||||||
| Performance of zinc white copper | Zinc white copper is an important variety of white copper, with excellent mechanical properties, excellent processing properties, especially the beautiful silver white. It is a famous imitation silver art copper alloy, with a standard composition of BZn15-20 alloy containing 15% nickel and 20% zinc. It is widely used in various countries to make various handicrafts, With the development of modern communication technology, zinc white copper has been used as an important plug-in component and also as an electromagnetic shielding shell for various electronic devices, such as crystal oscillator shells. In order to improve mechanical properties, corrosion resistance, and silver white luster, the engineering community has generally increased the nickel content in BZn15-20 alloy appropriately, resulting in the birth of new alloys such as BZn18-8 and BZn18-26. |

| Characteristics and uses of zinc white copper | Potentiometer uses slide, coin, token, eye frame, key, and has deep drawing performance. Liquid crystal oscillator housing, crystal housing, medical machinery, architecture, wind instruments, etc. | |||||||||||
| The Use of Zinc White Copper | Zinc white copper is widely used in the manufacturing of corrosion-resistant structural components, such as springs, sockets, covers, and other components for precision instruments and advanced electronic components, due to its excellent abradability, brazing resistance, stress relaxation resistance, high strength and elasticity, good corrosion resistance, and ease of electroplating, hot and cold processing. The zinc white copper with a small amount of lead has good machinability and cold workability, and is widely used for making precision parts such as clocks, optical instrument, etc. In addition, zinc white copper also has a broad market in areas such as musical instruments, tableware, glasses frames, and decorative engineering. | |||||||||||
