ERAMET's Alloys division, which includes the companies Aubert & Duval and Erasteel, designs and develops high-performance steel, metal powders and superalloys. These, as well as titanium and aluminum, can then be transformed by forging, rolling, closed-die forging, hot isostatic pressing or drawing.

The large range of products and processes in the Alloys division is designed for various industries where performance is essential. This is why the search for quality and customer satisfaction is a core concern for the Alloys division.


Since its creation, Aubert & Duval has always supported its customers with the most ambitious aeronautics and space programs (Concorde, Airbus A380, Boeing 787, Ariane 5, etc.). Thanks to its ability to meet the greatest of challenges, Aubert & Duval is one of today's world leaders for closed-die forged parts and long products for aerospace in aluminum, titanium, steels and high-performance alloys.

Aubert & Duval and Erasteel also develop innovative metallurgical solutions based on powder metallurgy technology.

ERAMET's Alloys division supplies aircraft and helicopter manufacturers with critical parts for engines, structures and landing gear. For the space market, the division supplies products for launchers and satellites.


Aubert & Duval is a major supplier to the energy sector. Its products are used in critical applications in environments with many constraints:

forged and closed-die parts and long products for nuclear reactors and generators;

forged parts for risers (long steel tubes) and pumps destined for oil production;

parts for gas and steam turbines.

Erasteel is active in this market, in particular through powder metallurgy, supplying metal powders. Transformed by its customers, these will be used under extreme conditions in oil and gas offshore applications and in power plants.

Land and sea transportation

Through its two subsidiaries, Erasteel and Aubert & Duval, the Alloys division provides and develops a wide range of metallurgical solutions for land and sea transportation: automotive sector, ships, submarines, etc.

Active for many years in the motor sports market, particularly Formula 1, steel from the Alloys division are used in mechanical components and critical parts such as injection systems, valves and even transmission systems.


With its ASP® range of products, Erasteel is the world leader in high-speed steel produced by powder metallurgy. Extremely wear resistant, they are used in the manufacture of cutting tools, such as drill bits, milling cutters and taps, but also for saws and industrial knives for metal, plastic, textiles, wood and even for gear-cutting tools.

Thanks to its expertise in various alloying techniques, Aubert & Duval is able to offer particularly reliable and productive tool steel, adapted to the requirements of each technology.

ERAMET's Alloys division thus produces a wide range of steel and alloys for the production of tools used in the shaping of metals, plastics and glass. The tools are subsequently used by sub-contractors in various industries such as the manufacture of automobiles, domestic appliances and electronics.


Of the many markets that use steels from Aubert & Duval, some are considered to be niche markets.

Therefore, the company provides the defense industry with forged and closed-die parts. These products are also used in the food industry, in particular in pascalization enclosure used in the cold pasteurization of foods, or even in bearings and gears manufactured by mechanical engineering companies.

The Alloys division all around us

Alloys and steels from the Alloys division are also present in numerous applications of our daily lives.

Erasteel’s high-speed steels are therefore used in many fields from medical to electronics, including the food industry. For example, we find Erasteel steels in bearings for scanners, dies for striking coins and even the tools used in cutting out diapers.

Steels developed by Aubert & Duval also have unexpected applications: in clockmaking, bicycles for the Tour de France and even prosthetic hips and various medical implants. In the kitchen, many items have been shaped by or are made of steel from this company.
