Copper Beryllium H04 is a precipitation-hardenable copper-beryllium alloy in a strain-hardened condition offering high strength and excellent electrical and thermal conductivity for critical aerospace and defense applications. The H04 temper (half-hard) provides intermediate strength levels with controlled elongation suitable for strip applications requiring moderate forming capability while maintaining superior fatigue resistance and non-magnetic properties.
