Copper Zinc Alloy C21000 for Industrial & Electrical Applications

Copper zinc alloy UNS C21000 is most commonly known for its resistance to corrosion. C21000 has superior corrosion resistance, good deep draw properties, is malleable, has moderate conductivity, all while possessing good strength. Typical uses for C21000 include ammunition components, coinage, medallions, and a wide variety of other applications. C21000 is a copper zinc alloy which is stronger and more durable than copper alloys. C21000 makes for a superior corrosion resistant, malleable, highly conductive metal for the industrial and electrical industries.

Choosing Copper Alloy C21000

Electric Materials’ C21000 Copper Alloy has been specifically developed for rotor bar applications. Close control of the chemistry, including trace elements, at our in-house casting facility, allows us to control the electrical properties within a very narrow range. This ensures our customers the same electrical properties each time they order. C21000 is often used in coin tokens and key blanks where corrosion is a key factor and conductivity are required.
