Die striking is used to make anything from findings to light weight earrings and more. Platinum iridium alloys are very suitable for this. Platinum’s density means a much thinner sheet of metal can be used and still be as strong as the heavier gauge necessary to do the same piece in gold.

Many wedding bands are fabricated by machining platinum from tubing. The recommended alloy for this manufacturing method in the US is platinum/ruthenium (Pt/Ru), a hard and flexible alloy. Ruthenium is another platinum group metal. Made into platinum tubing, this alloy is usually cut in “Swiss machines” or on a lathe, using diamond-cutting tools, to make wedding bands of many design variations. Tubing can be made several ways, ranging from extruding to pressing from a washer like disc. Most tubing is seamless. The wedding bands are then sliced off the tube and are shaped and cut to create the various designs.
Fabricating platinum jewelry has many benefits. The high melting temperature of the metal will make working with the finest wires possible. Its unparalleled strength makes platinum the ideal metal to securely hold stones in mountings, and the lustre that can be achieved by properly polishing platinum is second to none.

To inlay gold into platinum first cut a groove into the platinum with a bur. Then select a wire of gold smaller than the groove. Using your torch, melt the gold into the groove fusing it to the platinum. Because of the high melting point of platinum, you do not have to be concerned about melting the platinum jewelry. File the surface even and finish using emery papers.
