Nikel kumush holatida, "kumush" atamasi metallning rangini tavsiflaydi, mazmuni emas. Nikel kumush - nikel va/yoki rux bilan birlashtirilgan asosan misdan tashkil topgan asosiy metall qotishmasi. Bu qimmat bo'lmagan asosiy metall bo'lib, tashqi ko'rinishi kumushga o'xshaydi. Nickel silver is used in costume jewelry but should be clearly marked and described as a nickel alloy since many people are allergic to nickel.
