CDA 172 beryllium copper is resistant to corrosion, radiation and heat

This alloy boasts exceptional corrosion resistance and is highly resistant to stress corrosion, making it superior to materials like brass or nickel silver. It also provides better corrosion protection than copper-nickel or aluminum bronze when exposed to seawater. Consequently, it is considered an ideal material where both corrosion resistance and mechanical strength are required simultaneously. An oxide layer forms on its surface during age hardening, acting as a protective coating. This enhances its resistance to high temperatures.
