TUNGSTEN CARBIDES - When hardness is the point
carbide is a high performance material formed from tungsten and carbon.
Its most outstanding property is its hardness, which approaches that of
Tungsten carbide with consistently high quality
Starck provides a wide range of tungsten carbides, from very fine
grades with an average grain size of approx. 0.5 µm to very large
average grain sizes of approx. 50 µm. Moreover, nanocrystalline tungsten
carbides are being tested in new applications and for increasing
Certified quality management ensures the high
quality of our tungsten carbides with continuous analysis of its
properties. In this way, our customers can rely upon the consistent,
high quality of the products we supply, enabling them to produce high
quality tools while reducing their own process costs.
Process quality and raw material supply are assured
Starck is known for excellent quality and expertise gained over many
years in the production of tungsten carbide. With modern, advanced
systems and processes, H.C. Starck's own production takes raw material
to the intermediate product stage as ammonium paratungstate and then on
to finished tungsten carbide. In this way, the product quality can be
optimized over the entire process chain. Finally, experienced employees
with related expertise and our quality management ensure both process
and product quality.
H.C. Starck's production processes allow
the use of both primary and secondary raw materials. However, to ensure
a sustainable supply of raw materials, H.C. Starck focuses mainly on
recycling. Almost all tungsten containing residues or used hard metal
components, such as drills and milling cutters, can be reworked into
new, high quality tungsten carbide. A sophisticated recycling process
guarantees that the product made from secondary raw materials is not
inferior in any way to that made from primary raw materials. Naturally;
H.C. Starck also offers customers recycling services for tungsten products.
Support along the entire process chain
To help ideas become successful solutions, we support our customers as partners in the development and optimization of materials, products and processes. Our application technicians have outstanding materials expertise, detailed knowledge of metallurgical and chemical processes and long-term experience in numerous innovative markets, application areas and technologies. Understand each other and move forward together - that's the H.C. Starck way.
