卑金屬

卑金屬(或稱賤金屬基本金屬普通金属,英語:base metal)是除了贵金屬(precious metal)之外,其他所有的金屬。例如:等。

化學上,「卑金屬」都是用在當作容易氧化腐蝕的金屬上面的非正式稱呼,這些金屬很容易與稀釋的鹽酸反應產生氫氣,例如鐵、等。銅雖然不能跟鹽酸反應,但是因為它相對來說很容易氧化,所以也被視為「卑金屬」。與這類金屬相對是惰性金属(noble metal,也常稱為贵金屬)。

煉金術中,「卑金屬」意指很普通而且不昂貴的金屬,與主要包括金與銀的贵金屬為對比。煉金術士的長期目標就是將卑金屬變化成稀有金屬。

貨幣學中,錢幣過去都是從贵金属的含量來決定其主要價值。但是大多數的現代貨幣都是法定貨幣,並允許錢幣可以用卑金屬來製造。

採礦業經濟學中,「卑金屬」意指工業上不包括贵金属的黑色金屬有色金屬。這些包括銅、鋁、鉛、鎳、和鋅。
