CW614N (CZ121) brass bar is a commonly used brass alloy material with good processing properties and corrosion resistance. It is mainly composed of copper (Cu) and zinc (Zn), with a copper content of about 57-59% and a zinc content of about 39-41%. In addition, it contains small amounts of lead (Pb) and manganese (Mn) to improve its mechanical properties and corrosion resistance.

CW614N (CZ121) brass bar has the following properties:

1. High strength: able to withstand high pressure and impact.

2. High conductivity: excellent conductivity, can effectively transfer current, reduce resistance, improve the efficiency of the circuit.

3. Easy machining: good machinability and thread rolling and knurling characteristics, suitable for high-speed machining operations.

4. Good welding performance: it can be connected with other metals by fusion welding, brazing, etc. to improve the reliability and stability of the circuit.

5. Good corrosion resistance: able to resist certain corrosive environments.

It should be noted that the mechanical properties and corrosion resistance of CW614N (CZ121) brass rod are affected by factors such as processing and heat treatment. Before use, it is recommended to carry out the necessary heat treatment and surface treatment to improve its performance and service life.
