Monel

Kvake od monel metala

Monel, zvan još i Monel metal, je slitina nikla i bakra prozvana po Ambroseu Monellu. Patentiran je 1906. godine. To je vrlo skupa slitina, cijena mu je oko 5 do 10 puta veća od cijene bakra ili nikla.

Sastav

Monel se sastoji od približno 65 % nikla, 33 % bakra i 2 % željeza. Otporan je na atmosfersku koroziju te morsku vodu i razne kisele i alkalne otopine. Naziv Monel zakonski je zaštićen, sva prava drži Special Metals Corporation, iz Huntingtona u West Virginiji, SAD. Materijal se smatra prethodnikom nehrđajućih čelika i koristi se i danas.
