Abstract

Precious metals for jewellery are formed into semifinished material by chemical working. The precious metals are sheathed in soft iron with intermediate nickel coating and rolled, forged or extruded into required shape. Intermediate heat treatment is used. The sheath is finally removed by selective chemical attack.
