From gold to platinum, PX GROUP and more precisely PX PRECINOX, handle precious metals on a daily basis. Once the alloys have been made, they are worked by rolling and cold-drawing, and then deformed to obtain semi-finished products. They are then delivered to partner industries, mainly in watchmaking, jewellery and luxury goods.
Our products
Precious metals
STANDARD ROUND, RECTANGULAR AND TICK SECTIONS
PX PRECINOX offers a range of standard profiles from 1.5 mm to 24 mm, without tooling costs. They can be delivered in the form of straightened bars, coils or reels, depending on the product.
COMPLEX ROLLED, MILLED AND DRAWN SECTIONS
The firm’s reputation has from the outset been built on manufacturing shaped sections made by cold deformation. An extremely wide range of shapes can be wrought to customers’ specifications, by rolling, drawing and continuous milling. The profiles can be delivered in the form of straightened bars, parts, coils or reels, depending on the product.
WIDE ROLLED, MILLED AND DRAWN SECTIONS FOR BRACELET CLASPS
As for other sections, complex geometries can be produced using continuous milling technology. The applications relate to clasp blades and horns, as well as other products requiring wide sections. The sections can be delivered in the form of straightened bars, parts, coils or reels, depending on the product.
ALLOY COMBINATIONS
Precious metals based on gold, silver, platinum and palladium
Non-precious metals based on steel, copper, titanium
Other special compositions for specific applications in the field of medicine, aerospace, etc.
SHAPED OR PLAIN, SEAMLESS TUBES
The tubes are made without welding; they can be less than 1 mm in diameter to more than 40 mm, with a wall thickness varying from 0.08 mm to more than 5 mm. Deliverable in the form of straightened bars, parts, coils or reels, depending on the product.
CORED TUBES
Cored tubes represent a useful solution. They consist of a precious alloy tube filled with a steel, titanium or copper alloy core. These products are original solutions in the fields of watchmaking and jewellery.
Legislation on precious metals inspection recognises that a superior quality known as “gold crown” when the thickness reaches at least 200 µm, and enables the fineness to be marked if the thickness reaches at least 500 µm. Delivery in the form of straightened bars or parts.
Cored tubes filled with a copper alloy are advantageous for machining precision components. The copper alloy core can be chemically removed after machining by PX PRECINOX.

PX Precinox SA’s services range from the manufacture of rolled bands to the production of finished components. With its own machines or using subcontractors, PX Precinox SA takes care of your orders from the start all the way to whichever stage you prefer: cutting out, stamping, hollowing out, final machining, or polishing.
We have a huge range of standard tools to offer you an extensive palette of cutting-out patterns without the cost of re-tooling.
FILLER METAL IN SHEET FORMAT FOR WELDING
All welding compositions are made in the PX PRECINOX foundry. They are available in sheet format 0.3 mm thick, and 17 mm wide.
To enable their identification, the sheets are marked with the alloy number, its name and the melting range. They are delivered by weight.
TARGETS
PX PRECINOX supplies targets for PVD coating for the electronics industry, decorative coatings or special applications. The company supplies rectangular targets, milled and drilled according to the customer’s drawing, but also round targets. Available diameters are shown in the standard tools list. The alloys most often comprise fine metals. However, PX PRECINOX also produces targets made from specific-composition alloys.
PRECIOUS METAL ALLOYS
Gold, silver, palladium or platinum: whether opting for standard or all-new compositions, PX PRECINOX always strives to find the best solution.
