Quick answers
Is Nitinol non-combustible?
Declared reaction class in this atlas: A1 metal. Assemblies still need resistance tests.
Does Nitinol insulate?
Thermal mark 12/100 versus the atlas. Conductivity note: ~10–18 W/m·K.
What is the density band?
~6.45 g/cm³
How is it made?
Origin story: NOL 1959 Buehler (United States).
Can it be recycled?
Circularity mark 36/100 — editorial, route-specific.
Typical melting or failure heat?
~1310 °C

Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.

Ore, plantations or energy that feed primary routes.
Global trade
Nitinol moves as coils, bales, boards or chemicals — check HS codes, not vibes.
