PURPOSE:To obtain watch armoring parts in combined golden and white color with thin layers at low cost, by providing materials, obtained by joining gold alloy and stainless steel by turns, entirely or partially. CONSTITUTION:Gold alloy (gold 24K, 18K, 14K, or 10K carats fine) and stainless steel (304, 316, or 316L) are used to join gold alloy parts 1 and stainless steel parts 2 linearly by turns, or in a brocaded pattern, a lattice pattern, etc without using a brazing material. This is used as the armoring parts of a wrist watch, etc., for the whole or part of the watch armor. Then, recesses parts are formed in the stainless steel to charge gold by brazing, so that the excellent appearance is obtained at low cost because no brazing material is used. |
