Aerospace-Grade Wire
GTX Aerospace-Grade NP1 Wire — thermally qualified from –196°C to 1,000°C at NTU Singapore and Lectromec (NASA-certified, ISO/IEC 17025:2017). Specified for composite tooling, AESA substrates, thermal-management structures and airframe applications.
–196°C to 1,000°C. NASA-certified laboratory qualification.
Aerospace materials are specified against a brutally narrow envelope: they must survive cryogenic ground operations, atmospheric re-entry, and sustained high-temperature propulsion exposure without dimensional or chemical drift. NP1 ultra-pure nickel is one of the small number of materials qualified across that full range — and GTX supplies it at the tolerances aerospace procurement demands.

Qualified by Prof. Ramamurty (NTU Singapore) and Lectromec (NASA-certified).
Prof. Upadrasta Ramamurty’s metallurgy group at NTU Singapore characterised the NP1 wire across the full aerospace thermal envelope under repeated cycling. Lectromec (ISO/IEC 17025:2017 accredited, NASA-certified testing authority) issued aerospace-grade qualification.
The qualification dossier covers tensile retention, creep, thermal-fatigue, and dimensional-drift parameters across the specified range, with raw test data available to customers under the aerospace-procurement NDA framework.
