CZ112 Brass

CZ112 (CW712R) - a naval brass that finds typical use in marine, above-sea and subsea applications.

Our brass alloy benefits from excellent corrosion resistance and overall strength and retains these properties at cryogenic temperatures. The critical inclusion of 1% tin in the alloying process enhances the material's corrosion resistance and mechanical properties. Our product primarily composes of 60% copper with 39% zinc. CZ112 alloy also benefits from greater strength when compared to traditional alpha brasses.


Typical commercial applications include:

  • Higher strength compared to alpha brasses
  • Excellent corrosion resistance
  • Property retention at cryogenic temperature
  • Stronger, harder duplex structure
What is Naval Brass?

Traditional brass alloys contain primary alloying elements of copper and zinc. Naval brass also includes tin in the alloying process, resulting in an engineering material with performance characteristics suitable for marine applications. Naval brasses benefit from good corrosion resistance in fresh and saltwater environments and are more durable than typical brass alloys.


CZ112 (CW712R) finds use in commercial engineering applications including general machined components, above-sea and subsea hardware, marine components and heat exchangers.
