Nitinol REDOX

80 Percent: That’s how many fewer oxides are found in Redox™ nitinol alloy. With reduced oxide area and particle size, Redox offers enhanced microcleanliness and enhanced confidence.


80% fewer oxides for a cleaner, more pure material.

The presence of non-metallic inclusions and porosity is how the industry measures nitinol microcleanliness. Typical non-metallic inclusions are carbides (TiC), and intermetallic oxides (Ti4Ni2Ox). The size and distribution of inclusions like these play a critical role for device designers who work with nitinol.

In response to our customers’ challenges, Memry developed Redox. As the charts make clear, Redox offers significant improvements over SAES and ASTM F 2063 Standards for maximum inclusion area and size.

Availability and Applications

Redox is available for the following applications: tube, wire, strip, sheet, and component prototypes. What’s more, Redox benefits from Memry’s exclusive melting and processing techniques, which protect the integrity and preserved strength of the nitinol. This is an important consideration for the medical device industry, as well as industrial markets, as they move to smaller, lower profile devices with thinner structures.

chart: maximum inclusion area
Redox’s maximum inclusion area measures 1.2%, well below SAES Standard material.

Chart: Maximum inclusion size
The maximum inclusion size for Redox is an impressive 20μm, 6μm below SAES Standard material, and 19μm below the ASTM F 2063 Standard.
