Tantal – Plates, sheets and foils
Tantalum and tantalum alloys
Pure tantalum (R05200)
- Excellent workability
- High corrosion resistance
- Slightly higher mechanical strength than pure tantalum, but still good to machine.
- Better chemical resistance than pure tantalum in some environments.
- Working range up to 1600°C.
- Very high strengths, especially at high temperatures.
- Working range up to 2000°C
- Machining is much more difficult compared to the alloys mentioned above.
- Corrosion resistance is not as good as that of pure tantalum.
- Corrosion resistance similar to pure tantalum.
- Slightly more difficult to machine.
- In unmachined condition, some mechanical properties are better than these of pure tantalum.
The guaranteed maximum impurities of our molybdenum sheets are determined by ASTM B708

Produktion and Heat treatment
Tantalum sheets are usually cold rolled to minimise oxidation.
Annealing removes material tensions which occur during the production process, but causes a slight reduction in mechanical strength. These annealed sheets are much easier to machine.
Our tantalum sheets are normally annealed. If you require non-annealed material, please let us know.
