Kinaiya

Pisikal

An Copper, silver, ngan bulawan amo in membro san group 11 san periodic table; may'ada ini na mga metal usa na s-orbital electron ngan puno na d-electron shell na may kinaiya na may'ada hitaas na ductility, ngan electrical (59.6×106 S/m) ngan thermal conductivity, ika-2 na pinakahitaas (nasunod sa silver) sa mga puro na metal sa room temperature.

Alloy

Daramo an alloy san tumbaga o copper, ngan daramo liwat an pinaggagamitan. Brass an alloy san copper ngan zinc. Bronse naman an 10% copper ngan tin o lata. An alloy san copper ngan aluminum gintatawag na aluminium bronze. 
Sayo an importante na sangkap an copper sa alahas kaupod an silver ngan  bulawan. An carat solder na may'ada copper ginagamit sa pagtagaalahas pagliwat san kulay, katig'a ngan melting point san alloy.

An alloy san copper ngan nickel gintatawag na cupronickel,ngan ginagamit sa paghimo sinsilyo.
