Pure Metals only: High purity ultra low carbon and sulfur.
- Standards
Assume fabrication by powder metallurgy - UNS NO 2270, 2.4050
- Properties
Very low levels of C (20 ppm) and S (2 ppm) - These elements tend to segregate at grain boundaries resulting in hot shortening.; Cleanliness - Absence of non-metallic inclusions as Al, Ti or Si oxides.; Improved oxidation resistance - Development of a tightly adherent one-layer oxide scale instead of a twolayer customary one, which tends to flake off due to mismatch in thermal expansion.

- Labeling Claims
- High Purity
- Advantages and Features
Highest purity of ≥ 99.98%. hpulcas™ determines the degree of purity of its input material by standard using GDMS (glow discharge mass spectroscopy) and the gas and carbon content additionally using IGA (instrumental gas analysis). A total of 78 elements are determined, with measurement limits being treated as impurity levels. The only trace elements whose content exceeds 1 ppm are oxygen, nitrogen, carbon and iron. You can find more information about our purity standards here. [Link to State of Purity whitepaper via request form]; Due to the exceptionally high level of purity, HPN™ films exhibit consistent and reproducible physical properties; The mechanical properties can be adjusted within wide limits during processing. Due to the high level of purity, very low hardness values of ≥ 65 HV can be achieved in the annealed condition.; HPN™ foils can already be recrystallization annealed at low temperatures of ≥ 350 °C.; HPN™ foils are highly corrosion resistant to sea water, non-oxidizing acids, alkalis and many organic substances.; HPN™ foils are gas-tight up to small thicknesses.
