銅合金 Copper Alloy

銅或銅合金廣泛應用於通訊設備、電線、電機製造、電器導電材料等。熱的傳導率僅次於金、鉑及銀，因而多用於日常用具，如散熱器、冷凍機等製造。

銅的延展性及好，可製成板、棒、線、管、機械零件及貨幣、飾物等。銅與其他金屬形成何金，可彌補純銅之軟弱，做成堅硬美麗的黃銅、磷銅等各種金屬，精密的電子零件、日用品及美術品等，各有其不同的應用領域。

Copper or copper alloy are widely applied in communication equipment, wires, electrical manufacturing, electrical conducting materials. Heat conductivity is only next to gold, platinum and silver; therefore it is applied in heat sinks, cooling machines. Copper has excellent expansion; it can be made into plates, rods, wires
