Copper Beryllium H04
VerifiedmetalCopper 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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
