Muntz metal

Muntz metal or muntz brass ^[1] is a type of brass , an alloy of copper base with zinc (39 - 43%), in which lead was sometimes added (0.8 - 1.9%). Available in the form of semi-finished products (pipes, strips, wire, tapes, rods), used for mass production of parts in instrumentation and engineering .

Muntz metal was proposed in 1832 by the British industrialist and metallurgist J. Muntz, it has good mechanical properties, a combination of high ductility and corrosion resistance with machinability for various types of cold and hot metal processing (cutting, pressure processing, etc.) ^{[2] [3]}
