What we do

Markets, metallurgy, operations, service centres and support functions work as one front office, accountable from your specification to serial supply.

01

Engineer

We design and co-develop alloys and specific components according to your specifications. Our application engineers follow the part from the first drawing to qualification, and design it for circularity and for sovereignty of supply.

02

Manufacture

We melt, cast, forge, extrude, roll and draw in our own plants, from circular raw material to semi-finished and near-net-shape products. Properties, dimensions and documentation are controlled and certified at every step.

03

Supply & service

We produce on three continents and hold stock close to you, with technical support and supply chain services from our service centres. The relationship continues from first fit to MRO and recycling.

History

90 years of metallurgy, accelerated by global expansion

1934Metallurgical foundationsFrom 1934 to 2005, we build a deep expertise in copper and nickel alloys.
2006TransformationFrom 2006 to 2016, new owners arrive and the industrial base is repositioned.
2017International expansionFrom 2017 to 2024, acquisitions and the roll-out of a service centre network in the United Kingdom, North America, Asia and Europe.
2025A new growth chapterOwned by Astorg since 2025, we are expanding globally in critical alloys for critical applications. Four companies join the group that year: Allied Copper Alloys Ltd, AW Fraser Ltd, M Lego and Manufacture pour l'Extrusion d'Alliages (MEA).
