বিষয়ে Copper
Copper is a soft, malleable, ductile metal with very high thermal and electrical conductivity. It is one of the few metals found in directly usable metallic form in nature. Copper has been used for at least 10,000 years.
Uses & Applications
Electrical wiring, plumbing, roofing, coins, electronics, antimicrobial surfaces, and cookware.
মজা কথা
Copper is naturally antimicrobial -- bacteria die within hours on copper surfaces, which is why hospitals use copper alloys for door handles.
