Precious metals

Round and shaped tubes

Tubes are manufactured seamlessly from bars or coils, with the wall size requested by our customer. Their cross-section is round or specifically shaped according to our customers’ drawings.

Cold-drawing obtains a surface finish ready for final polishing. In addition to the high-quality finish, the complex tube shape incorporates functional geometric requirements and reduces the weight of precious metals.

Within these products, precious metal cored tubes are original solutions for the watchmaking, jewelry and industrial sectors.
