CZ114
High Tensile Brass alloys are compositions of Copper and Zinc. CZ114 belongs to the category of duplex or alpha/beta alloys. This particular brass alloy, CZ114, is renowned for its versatility, offering high strength, excellent hot workability, and machinability, and it is occasionally known as either Manganese Bronze or High Tensile Brass in the field of engineering materials.
