Titanium in 1970s: CP grades

Scores compare Titanium with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Titanium (Ti (α/β alloys)) is a family of grades whose density 4.51 g/cm³, heat band 1668 °C, and fire letter A1 metal. Titanium is sold as grades, not as a single substance. Chemistry Ti (α/β alloys), density 4.51 g/cm³, heat band 1668 °C. This atlas treats Titanium as a system: mill route, coatings, tests and the cavity it sits in.

Conductivity note: ~22 W/m·K. Insulation score 14/100 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: Kroll process 1940, Luxembourg / US. The process chapter follows feedstock → conversion → forming → finish → install.
