Wolfram and Molybdän are key materials for future technologies. From medical technology and semiconductors through to aerospace – our products meet the highest requirements across a wide range of industries.
Energy & High-Performance Mechanical Engineering
Whether in turbines, generators, offshore facilities, plant engineering or industrial high-performance machinery: endurance, high mechanical strength, wear resistance, thermal conductivity and often erosion and corrosion resistance are critical here.
Our materials are used in components such as bearings, seals, valves, housings, heat exchangers, wear-protection layers and other parts that operate continuously under high loads. In the energy sector – e.g., wind turbines, power plants or the oil and gas industry – reliability over long operating periods and resistance to environmental influences such as moisture, saltwater, temperature fluctuations and aggressive media are essential. Through our development work, we ensure that material parameters such as strength, thermal expansion, density and surface characteristics are optimally tailored to the respective application.
Automotive & Aviation
In aerospace and the automotive industry, every component stands for precision, safety and efficiency. Wolfram and Molybdän materials are indispensable in high-temperature zones thanks to their density, stability and heat resistance – for example in engines, braking systems, turbochargers or shielding.
Their outstanding resistance to thermal fatigue enables use in dynamically loaded components where conventional materials would fail. In addition, our materials contribute to precise performance over long periods due to their dimensional stability and low thermal expansion. Whether for prototypes, series components or high-temperature test systems – we supply solutions precisely tailored to the respective requirements.
Medical Technology
Medical technology places the highest demands on materials: biocompatibility, sterilisability, precise dimensional accuracy and traceability are just a few of the requirements. At Molytun, our high-performance materials are used wherever tight tolerances and reliable function over long service lives are critical – e.g., in implants, surgical instruments, diagnostic equipment and prostheses.
We provide materials characterised by excellent corrosion resistance, low deformation under load, high cleanability and sterilisability, and chemical stability. For applications involving contact with body fluids or use in sterile environments, our materials ensure that both safety and function are fully met. Through close collaboration with medical technology engineers and manufacturers, we support material selection, processing questions and validation – for example with regard to ISO standards, biocompatibility testing or FDA/CE registration.
Welding & Surface Engineering
In welding and surface engineering, maximum precision and durability are essential. Materials such as tantalum, Wolfram and Molybdän are ideal for electrodes, contact nozzles and coating elements due to their high melting points, electrical conductivity and corrosion resistance.
They ensure consistent energy transfer, minimise burn-off and contribute to stable weld quality. In coating technology, they are used for thermal spraying, PVD or CVD processes, where temperature and oxidation resistance determine the service life of tools and components. Molytun supplies customised semi-finished products and components distinguished by purity, stability and surface quality – for precise, durable and reproducible results.
Semiconductor Industry
Semiconductor manufacturing is a field with extremely high requirements for purity, chemical resistance, temperature stability and mechanical precision. In systems for wafer production, lithography, etching, coating or handling aggressive chemicals, materials must perform reliably without causing contamination or deforming.
Our materials are used in this industry wherever, for example, ultra-high-purity components are required: seals, housings or parts that come into contact with cleaning solutions and process chemicals. When dealing with vacuum conditions, large temperature fluctuations and high-precision positioning, our materials also make an important contribution thanks to their thermal stability and mechanical strength. In addition, they help minimise downtime because they are durable and processes need to be interrupted less frequently.
Chemicals
In the chemical industry, materials are exposed to extreme conditions: aggressive acids, bases and high temperatures demand absolute resistance. Tantalum offers nearly unmatched corrosion resistance – even against aqua regia, hydrochloric acid or sulphuric acid – making it ideal for reactors, heat exchangers, piping and linings.
Thanks to its passive layer, tantalum remains stable even under long-term exposure and ensures process reliability while maintaining high purity in the end products. Our manufacturing capabilities enable complex tantalum geometries, precisely welded and inspected to the highest quality standards. This creates long-lasting solutions that minimise downtime and provide lasting protection for chemical plant operations.
