Claim Text:
1. A method of producing a silver-white copper alloy, comprising the steps of: (a) providing a silver-white copper alloy, comprising: (b) hot-rolling the silver-white copper alloy; and (c) cooling the hot-rolled silver-white copper alloy without quenching from a temperature immediately after the hot-rolling to a room temperature, wherein a cooling rate of the hot-rolled silver-white copper alloy in a temperature range of 400° C. to 500° C. is higher than or equal to 1° C./sec to provide a metal structure of the silver-white copper alloy having an area ratio of β phases dispersed in an α-phase matrix is 0% to 0.9%, wherein the silver-white copper alloy has superior bactericidal and color fastness properties.
