Our products

Precious metals

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.

PRECIOUS METAL PROFILES

Wide or shaped non-precious metal sections are an inherent part of PX PRECINOX’s in-house tailored solutions, tailored to every customer’s requirements.

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.

PRECIOUS METAL TUBES

From precision precious metal tubes to “gold crown” tubes, the group supplies original solutions, aimed mainly at the fields of watchmaking and jewellery.

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.
