🩺How it is made

01 Feedstock

Ore, monomer, fibre, mineral or scrap that can legally become Nitinol.

02 Conversion

NOL 1959 Buehler

03 Forming

Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.

04 Heat / cure

Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.

05 Finish

Coatings, sizings, facers, galvanizing, anodising, painting.

06 Install

Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.

Primary

Virgin route around United States.

Recycled / secondary

Recycling exists but quality or energy often disappoints.

Specialty

High-spec grades leave the commodity mill.

Site-applied

Coatings, sprays, casts — the factory is sometimes a jobsite.

Envelope

Melting/softening ~1310 °C; conductivity ~10–18 W/m·K.

Environment

Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Nitinol.

Code

Fire class A1 metal is a starting letter, not a wall rating.
