metal· Cu
Copper is a transition metal prized for its exceptional electrical and thermal conductivity, corrosion resistance, and ease of forming. It is one of the most widely used metals in electrical infrastructure, plumbing, heat exchangers, and electronics, chosen when efficient current or heat transfer is essential and the cost of alternatives like silver cannot be justified. Engineers specify copper for applications where both conductivity and mechanical workability are critical, and where its reddish color and antimicrobial properties provide added functional or aesthetic value.

Regulatory Screening
Environmental
Export Control
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.
