The optimal material for your application
You can select from a number of materials to find just the right one for your requirements:
Mo
Molybdenum has versatile applications. It is creep-resistant, has a high rigidity, low thermal expansion, and a high thermal conductivity. It is also corrosion-resistant compared to many other metal and glass melts.
TZM
Titanium-zircon-molybdenum. This is a solid solution- and particle-reinforced molybdenum alloy with very high strength even at high temperatures. It has a higher recrystallization temperature and creep resistance than pure Mo.
MLR
With a lanthanum oxide content of 0.7% by weight, this stabilized molybdenum has a high creep resistance and high recrystallization temperature. It is supplied in a recrystallized version.
MLS
With a lanthanum oxide content of 0.7% by weight, this stabilized molybdenum has a high creep resistance and high recrystallization temperature. It is supplied in a stress relieved version to make further processing easier.
W
Tungsten has the highest melting point of all metals, is creep-resistant, has a good electrical conductivity, high rigidity, and low thermal expansion.
WVM
Potassium-doped tungsten with a stacked structure that ensures increased dimensional stability at high temperatures.
WL10
With a lanthanum oxide content of 1% by weight, this stabilized tungsten has a high creep resistance, high-temperature stability, high recrystallization temperature, and a lower electron work function compared to pure tungsten.
TaS
Tantalum in sintering quality with a high chemical resistance and good formability even below room temperature. Extremely fine-grained structure that has advantages for many deep-drawing applications.
TaM
Tantalum in melting quality with a high chemical resistance and good formability. Just like TaS, TaM is also particularly corrosion-resistant.
Nb
Niobium in melting quality with a high chemical resistance but significantly lower density than tantalum.
Our technologies and processes for sheet manufacturing
- The highest purity is ensured via automatic powder handling and process control that is continually being upgraded in the critical process steps powder production, pressing, and sintering
- Equipment from our hot and cold rolling mills with modern thickness control systems
- Highly dynamic, hydraulic gap control for maintaining the strictest product tolerances
- Automatic handling in critical process steps for sheet and ribbon production ensures high surface qualities
- Optimized process chain throughout the entire production process from powder to completed semi-finished product enables excellent mechanical properties such as good re-usability
In addition, we also have years of experience and the required skill for processing our semi-finished products into finished products. For example, we produce complex mounting parts such as hot zones for high-temperature furnaces.
Everything from a single source – from the powder to the finished sheet
We do everything ourselves when it comes to the production of our sheets. From raw material to the final product, including the development of new materials. This is how we guarantee the highest quality for our sheets.
OxideMolymet (Chile) is the world's largest processor of molybdenum ore concentrates and our main supplier of molybdenum trioxide. The Plansee Group holds a 21.15% share in Molymet. Global Tungsten & Powders (USA) is a division of the Plansee Group and our main supplier of tungsten metal powder.
Tungsten and tantalum from conflict-free sources
Tungsten and tantalum are partially mined in regions that are considered conflict and high-risk areas and are therefore classified as "conflict minerals." As a company aware of its responsibilities, we take particular care when sourcing raw materials.
Based on a wide range of measures such as the RMAP Recognition Certificate, we ensure that we do not source or use any raw materials from socially, ethically, or ecologically questionable sources.
Please see our company section for more about how we take our responsibility seriously and which certifications we have:
Short delivery times and clearly presented price scales – it's not just sheets, we also have rods, wires as well as products made out of molybdenum, tungsten, and tantalum available for you in configurable dimensions in our Plansee online shop.
