He 63.546 ke kaumaha o ke keleawe, ka mānoanoa 8.92g/cm³, ka helu heheʻe 1083.4±0.2 ℃, kahi paila 2567 ℃. He ʻulaʻula melemele ke ʻano kino a ke hoʻomaloʻo ʻia e ulu aʻe ka ʻōlinolino metala. Loaʻa ka paʻakikī kiʻekiʻe o ke keleawe, ke kūpaʻa ʻana, ka ductility maikaʻi, ka pale ʻana i ka corrosion, ka uila a me ka thermal conductivity. e hoʻohana ʻia i nā ʻano hana like ʻole. Loaʻa nā ʻāpana keleawe i nā waiwai mechanical maikaʻi loa a me ka haʻahaʻa haʻahaʻa, ʻo nā ʻāpana keleawe nui nā keleawe (copper/zinc alloys) a me nā keleawe (copper/tin alloys me nā bronzes alakaʻi a me nā bronzes phosphor). Ma waho aʻe, ʻo Copper kahi metala paʻa no ka mea kūpono loa i ka hana hou ʻana.
Hiki ke hoʻohana ʻia ke keleawe maʻemaʻe kiʻekiʻe ma ke ʻano he mea hoʻopaʻa no nā laina hoʻoili mana, nā uwila uila, nā uwea a me nā busbars, nā kaapuni hoʻohui nui, a me nā hōʻike papa pālahalaha.

ʻO Rich Special Materials kahi mea hana o Sputtering Target a hiki iā ia ke hana i nā lako Copper Sputtering me ka maʻemaʻe a hiki i 6N e like me nā kikoʻī o nā mea kūʻai aku. No ka 'ike hou aku, e 'olu'olu e leka uila mai.
