Nitinol in : Grades
Read the condition on Nitinol before the nickname. Year , line “Grades,” figure 1. Foams, VIPs and moist batts drift; quote aged values. A material is what it is made of, the condition it survives, and where it goes afterward. Nitinol under “Grades” in should say which, with 1 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
This atlas treats Nitinol as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~10–18 W/m·K. Insulation score 12/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1 metal. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: NOL 1959 Buehler, United States. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: titanium. Circularity mark 36/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Nitinol honest.
The medical metal without the phase trick. Another lab celebrity with thinner products. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation. Declared performance after blowing-agent or moisture drift. The zone where heat or chemistry changes the datasheet.
The label keeps Nitinol, , and 1. “Grades” is the condition on the figure.1
