UNS R60702 0.02mm high-purity zirconium foil

Product Description

The 0.02mm 702 zirconium foil—an industrially pure zirconium strip or foil with a thickness of just 20 microns, manufactured to the UNS R60702 standard—represents a highly challenging product in the realm of zirconium processing. It retains the excellent corrosion and temperature resistance of 702 pure zirconium while offering the high flexibility and exceptionally high specific surface area characteristic of ultra-thin materials.

Suitable for use in electronic vacuum devices and semiconductors, this material serves as a highly efficient getter, particularly for high-temperature applications. Thanks to its exceptionally large specific surface area, it rapidly absorbs trace amounts of residual active gases within the chamber during high-temperature operation, thereby maintaining an ultra-high vacuum over the long term and extending the service life of your products.

1. Suitable for use in electronic vacuum devices and semiconductors, it serves as a highly efficient getter—specifically a high-temperature getter material. Thanks to its exceptionally high specific surface area, it rapidly absorbs trace amounts of residual active gases within the chamber during high-temperature operation, thereby maintaining an ultra-high vacuum over the long term and extending your product's service life.

2. Suitable for precision instruments and military blasting applications; its 0.02mm thickness allows for instantaneous temperature rises and vigorous, exothermic oxidation reactions when stimulated by a weak current (leveraging zirconium's high energy-release characteristics), ensuring extremely precise and reliable ignition timing control.

3. Suitable for metal cladding and composite lining in extremely corrosive environments; it delivers corrosion resistance comparable to that of equipment made entirely of zirconium while significantly reducing your material costs.

4. Suitable for cutting-edge scientific research and aerospace applications (such as thermal protection and heat shields); the foil's minimal thickness results in a negligible cross-sectional area for solid-state heat conduction between layers, effectively blocking high-temperature radiant heat.

In chemical, electrolysis, and high-corrosion system design, why do engineers choose UNS R60702 Foil?

Titanium (Gr2) corrodes rapidly in hydrochloric acid and dilute sulfuric acid;

Stainless steel suffers from pitting and perforation;

Nickel (Ni200) performs well in alkaline environments but shows limited stability in certain acid systems;

UNS R60702 Foil provides longer service life and higher safety in acidic environments;
