1959
Buehler NOL
William Buehler’s team at Naval Ordnance Lab named NiTiNOL.
Nitinol did not arrive as a finished commodity. NOL 1959 Buehler around United States still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

Timeline
1959Buehler NOL
William Buehler’s team at Naval Ordnance Lab named NiTiNOL.
1961Coffee-pot demo
Folded strip unkinks in hot water — the myth and the lab both persist.
1970sOrthodontic archwires
First large medical market.
1980sPipe couplings
Cryofit aero hydraulic couplings.
1990sSelf-expanding stents
Nitinol cages in vessels.
2000sASTM F2063
Wrought NiTi medical spec.
2010sAdditive NiTi
Porous implants, still tricky oxygen.
2010sActuator wires
Robotics and consumer gadgets of mixed reliability.
2020sFatigue standards
Million-cycle claims need waveform honesty.
2020sNi-free cousins
Ti-based SMAs for nickel-sensitive patients.

Carbon fibre
Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.
Overall 49 ⬡Graphene
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.
