Titânio is one of 32 materials in this atlas, grouped under metals: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare Titânio 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.

Introdução profunda

Deep dive: Titânio

Titânio (Ti (α/β alloys)) is a family of grades whose density 4.51 g/cm³, heat band 1668 °C, and fire letter A1 metal.

What “the material” actually is

Titânio 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 Titânio as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

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.

How it is made and used

Origin: Kroll process 1940, Luxembourg / US. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: steel.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 48/100. Ask which scrap, which certificate, which year.

Perguntas frequentes

Is Titânio non-combustible?

Declared reaction class in this atlas: A1 metal. Assemblies still need resistance tests.

Does Titânio insulate?

Thermal mark 14/100 versus the atlas. Conductivity note: ~22 W/m·K.

What is the density band?

4.51 g/cm³

How is it made?

Origin story: Kroll process 1940 (Luxembourg / US).

Can it be recycled?

Circularity mark 48/100 — editorial, route-specific.

Typical melting or failure heat?

1668 °C

What should it be paired with?

steel: Cheaper mass where density is allowed.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
