Brass CZ114 Uses

Brass CZ114 is commonly used in various applications, including marine and industrial environments. Its high-strength properties and excellent corrosion resistance make it an ideal material for pipes, tubes, and fittings. It is also used for bearings, bushings, valve stems, and other precision components. It is commonly used in marine hardware, such as propellers and shafts, and for fasteners, locks, handles, and other hardware components.

Brass CZ114 Corrosion Resistance

Brass CZ114 has excellent corrosion resistance, making it ideal for marine and industrial environments. The additional elements found in the alloy provide an added layer of protection against corrosion. When exposed to seawater or other harsh environments, brass CZ114 will develop a patina layer that will help protect the material against further corrosion.

Brass CZ114 Heat Treatment

Brass CZ114 is typically not heat-treated, as it already possesses excellent mechanical and physical properties. However, it can be annealed at around 550 degrees Celsius if required. This will help to improve its machinability and workability.

Brass CZ114 Machining and Welding

Brass CZ114 is an excellent material to machine, with the addition of lead making it especially easy to cut and form. It can be machined using traditional turning, milling, and drilling methods. It can also be welded using brazing or soldering methods. However, it should be noted that brass CZ114 should not be welded using arc welding methods, as this can cause the material to become brittle and crack.


In conclusion, brass CZ114 is an excellent choice when high-strength and corrosion-resistant material is required. Its exceptional mechanical and physical properties and ease of machining and welding make it an ideal material for various applications. Whether used for marine hardware or precision components in industrial environments, brass CZ114 is a reliable and cost-effective choice.
