1. Cyflwyniad
Aloion fecral a ddefnyddir mewn ystod eang o gymwysiadau tymheredd uchel.
Mae gan Constantan [Cu55NI45] gyfernod gwrthiant tymheredd isel ac fel aloi copr, mae'n hawdd ei sodro. Mae aloion gwrthiant cyson eraill yn cynnwys manganin [Cu86mn12ni2], cupron [Cu53ni44mn3] ac Evanohm.
Mae gan y teulu Evanohm o aloion nicel-Chrome [Ni72Cr20mn4Al3Si1], [ni73cr20cu2al2mn1si], wrthwynebiad uchel, cyfernod gwrthiant tymheredd isel, grym electromotive isel (potensial galvani) pan fydd yn gyswllt â chopr, regardiau uchel, a chryfder uchel ei reglife.
