銅(拼音:tónɡ,注音:ㄊㄨㄥˊ;英語:Copper),俗稱红铜或者紫铜,是最早發現的化學元素,化學符號为Cu(源于拉丁語:Cuprum),原子序數为29,原子量為63.546 u。純銅是柔軟的金屬,表面剛切開時為紅橙色帶金屬光澤、延展性好、導熱性和導電性高,因此在電纜、電氣和電子元件是最常用的材料,也可用作建築材料,以及組成眾多種合金,例如用於珠寶的紋銀,用於製作船用五金和硬幣的白銅以及用於應變片和熱電偶的康銅。銅合金機械性能優異,電阻率很低,其中最重要的是青銅和黃銅。此外,銅也是耐用的金屬,可以多次回收而無損其機械性能。 銅是在自然界中可以直接使用的金屬的其中一種(天然金屬),這使得其在西元前8000年時被多個不同地區的的人們使用,在數千年之後,銅在西元前5000年成為首個從硫化礦石中冶煉出的金屬;在西元前4000年成為第一個在模具中塑形的金屬,更在西元前3500年與另一種金屬錫鍛造成了人類史的第一個合金——青銅。在古羅馬時期,銅礦大多在賽普勒斯開採,同時也使這種金屬得到最初的名字Cyprium(也就是賽普勒斯的金屬),之後演變為Cuprum(拉丁語),而現在常用的copper則是於西元1530年前後第一次被使用。 銅在自然界中經常形成二價的銅鹽類,它們使藍銅礦、孔雀石和綠松石等礦物具有藍色或綠色,並且在歷史上也廣泛用作顏料。氧化成銅綠的銅經常被用在建築物的屋頂上。而有時銅也被用在裝飾藝術上,而且不管是元素型態或形成化合物的銅都會被利用。另外,銅化合物用作、殺真菌劑和木材防腐劑。 銅是所有生物所必需的微量膳食礦物質,因為那是呼吸酶複合體-細胞色素c氧化酶(cytochrome c oxidase)的重要組成成分。在軟體動物和甲殼類動物中,銅是組成血液色素血藍蛋白(blood pigment hemocyanin)的成分,而在魚類或其他脊椎動物中,則被鐵血紅蛋白複合體給取代。另外,在人體中,銅主要分布在肝臟、肌肉和骨骼中,而一般成人每公斤體重約含有1.4至2.1毫克的銅。
