Description
Brass alloy CZ121 / CW614N is used for machining. It has Lead added to the composition to improve machinability. The Lead remains insoluble in the microstructure of the brass and the soft particles act as chip breakers.
• The most widely used of all the brasses due to its suitability for high speed machining operations and also the manufacture of intricate parts.
• The highest machinability of any copper alloy, excellent hot formability and good corrosion resistance.
• Typically used for wide variety of machined components made on high speed lathes including screws, bolts, nuts, bushing, pins, washers,
butts, hinges and also locks and components for watches.
