Special alloys to your specification
We produce cast semi-finished products from special alloys for industrial and medical technology as well as for mechanical, aircraft and shipbuilding – to your specification and in small to medium-sized batches.
We cast special alloys in continuous casting, chill casting and investment casting, and we atomise metal powder – for your custom applications.
Our manufacturing processes
Special alloys on a cobalt, nickel and iron base – from fine powder to cast semi-finished products. We manufacture in small to medium-sized batches to your specification, at our site in Willich Müncheide near Düsseldorf.
Welding rods
Welding rods and wires in special alloys on a cobalt and nickel base, manufactured to your specification.
- Cobalt and nickel base
- Diameters from 10 mm down to 0.15 mm
- Special dimensions on request
Chill casting
Cast semi-finished products in chill casting – from prototype to medium-sized batches, in your alloy and dimension.
- Cobalt and nickel base
- Small and medium-sized batches
- Custom dimensions
Powder atomisation
Metal powder from our own nitrogen atomisation. Our speciality is fine powder below 10 µm.
- Cobalt, nickel and iron base
- Fine powder below 10 µm
- Nitrogen atomisation
We also offer continuous casting and investment casting, develop custom special alloys and design your components using modern CAD methods. Talk to us – including about unusual requirements.
Fast project completion
Every project is completed on time and within budget thanks to precise planning and coordination.
Customer-oriented approach
We listen, plan and deliver exactly what you need – for a smooth process from start to finish.
Quality assurance
Certified work that meets German standards, with attention to detail and lasting durability.
Research and sustainability
We research new alloys and manufacturing technologies – for materials that meet the demands of tomorrow.
Responsibility is part of our craft: we return metals to the loop consistently and deliberately purchase recycled material. Part of our electricity we generate ourselves, from the photovoltaic system on our roof.
