| ANNEALING | 650 °C for 20 to 30 minutes then quenched in water. In order to avoid oxidation, work under reducing atmosphere. |
| COLD WORKING | The amount of coldwork completed before annealing should be between 30% and 75% reduction in area. |
| SOLDERING | By torch or furnace. The cadmium-free solder N° Au 585/322 (740-760 °C) is strongly recommended. For alternatives please see list of solders. |
| PICKLING | with DESOXYD (following operating instructions) or with hot 10% sulphuric acid. The slight change of colour which could appear can be removed by polishing. |
