Pure copper Purity: 99.9% Form: Cut wire Melting point: 1084.62¯C Density: 8.9 g/cm¸ This offer contains pure copper (Cu99.9) in the form of small wire sections. The pieces have a wafer-thin tin strip on the front. This makes the copper ideal for tin-containing copper alloys, but the copper can also be used for non-tin-containing alloys. Examples of applications include the alloying of bronzes, brasses, gunmetal alloys and as an admixture in food tin alloys. We can supply you with copper wire cuttings in 25kg buckets on request.
