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

Nitinol earns its keep in systems: a beam, a batt, a fibre blend, a coated steel — rarely a lone coupon.
Products below are cultural landmarks as much as SKUs.
Sectors
Transport
Mass, fire and fatigue rewrite the grade list.
Energy
Heat, voltage and hydrogen compatibility.
Consumer
The volume that pays for the mill.
Medical / food
When allowed — extractables and allergies matter.
Defence / safety
Ballistics, FR clothing, fire stops.

Carbon fibre
Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.

A one-atom carbon sheet — Nobel-era physics, composites hype, and a few honest electronics and barrier uses.
Overall 50 ☁️Aerogel
A nanoscale silica sponge — among the lowest solid λ values, fragile unless blanketed, and A1 when purely inorganic.
Overall 60 ☀️Perovskite (PV)
ABX3 halide crystals that jumped laboratory solar efficiency — still fighting humidity, lead and lifetime.
