Typho

Foamed Titanium Alloy
Foamed Titanium Alloy, or Typho, refers to a class of materials used in Human industry. These are solid titanium alloys with gas-filled pores comprising 70-95% of the internal volume. The properties of the foam depend on the size and the interconnectedness of the pores, as well as a dizzying variety of post-treatment processes, and so individual Typho variants have been tailored to thousands of applications.

Etymology
Foamed metals have existed on the commercial market since the twentieth century. Aluminum foams were more common due to their workability and ease of manufacture, but titanium foams were developed for aerospace and biomedical applications.

In the 24th century, industrialist Harry Stine invented a number of zero-G manufacturing processes that put production costs into a nosedive. Stine's products became so ubiquitous that their trade names, Typho for titanium foam and Alfoa for aluminum foam, are in common use two hundred years later.
