We produce the highest quality ribbons made of refractory metals in our ultra-modern production facilities. Our equipment enables us to offer a wide range of products, giving you diverse possibilities. We can also manufacture large quantities without any problems. You can then rework and/or form our ribbons according to your specific requirements.

Thanks to our high production capacities, we can manufacture ribbons in large quantities without difficulty.
Our one hundred years of experience in powder metallurgy and our state-of-the-art systems enable us to guarantee you the best quality for every ribbon. Whether shiny or pickled, for punching or in deep-drawing quality: we can adapt our products to your specific application.
Our multi-roll stands enable us to manufacture ribbons with lengths up to almost 1 km and with a minimal thickness of 15 µm. This allows us to deliver ribbons in thicknesses of 15 µm to 0.76 mm and widths of 1 mm to 360 mm. The thinnest ribbons can thus be up to 1000 meters in length.
We can provide the following dimensions:
| Material | Thickness in mm |
| Mo | 0.015 to 0.762 |
| MLS | 0.381 to 0.762 |
| MY | 0.015 to 0.200 |
| MY-ESS | 0.015 to 0.042 |
| TaM | Upon request |
| Nb | Upon request |
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.
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.
MY / MY-ESS
With a yttrium oxide content of 0.47 % by weight and Cer oxide content of 0.08 % by weight, this particle-reinforced molybdenum adheres well to quartz glass and has good weldability.
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.

We do everything ourselves when it comes to the production of our ribbons. From raw material to the final product, including the development of new materials. This is how we guarantee the highest quality for our ribbons.
Short delivery times and clearly presented price scales – it's not just MLS ribbons, we also have sheets, rods, wires as well as other products made out of molybdenum, tungsten and tantalum available for you in configurable dimensions in our Plansee online shop .
