El cromo funde a unos 3,465\u00b0F (1,907\u00b0C), muy por encima de las temperaturas normales de fusi\u00f3n del cobre, por lo que agregarlo como aleaci\u00f3n maestra permite que se disuelva de forma r\u00e1pida y uniforme con menos p\u00e9rdida que el cromo puro. Su uso principal es la producci\u00f3n de aleaciones de cobre al cromo como la C18200 y la C81500, que combinan alta conductividad el\u00e9ctrica y t\u00e9rmica con la resistencia y la resistencia al ablandamiento necesarias para electrodos de soldadura por resistencia, contactos el\u00e9ctricos y componentes de moldes. El grado al 5% permite un control m\u00e1s fino de peque\u00f1as adiciones de cromo que la aleaci\u00f3n maestra al 10%.
