Foamed Titanium

Foamed Titanium is used extensively within ships, as a lightweight, but reasonably strong filler material that provides a fair amount of protection. As such, most military ships will have at least a few decimeters of the stuff behind their primary armour. However, it is also often found inside people, acting as reinforcement or replacement for bones.
The porosity of the sample greatly influences the performance and properties of the metal, with higher density being nearly indistinguishable from regular titanium, while a low density may be more like a dark aerogel. On occasion, low density foam is used within a tank to give it a much higher structural integrity, at the cost of lower flow and volume. These are sometimes used as armour plates on critical systems, a titanium foam with water impregnated throughout, as it very effectively stops the blow.
It can be made out of many different alloys of titanium, the one described below is that used as armour on ships, but it can be made more bio-compatible with a different alloy.

Properties

Material Characteristics

The raw titanium foam looks and feels like essentially very light titanium.

Physical & Chemical Properties

While quite strong to a human touch, this material is easily able to absorb a blow, thus protecting the superstructure underneath. It is dangerous to touch the foam itself, as it can easily give a metallic splinter. It also has excellent thermal insulation, keeping the hot armour from melting the crew.

Compounds

Made of a Low-Ox Grade 6 Titanium alloy, foamed in a low pressure helium atmosphere.

Origin & Source

This is made of an alloy of titanium, with a little bit of aluminium and tin. It also requires a noble gas to foam without oxidation, and so helium is typically used.

Life & Expiration

The foam must be replaced if squashed, but can be melted down and refoamed aboard most large ships.

History & Usage

Everyday use

In everyday life, most people use it inside of their bodies, as a bio compatible, light, strong metal.

Refinement

To be used as foamed titanium, it must be alloyed, then melted and poured over a space-holding material, and then the space holder must be removed and replaced with a noble gas.

Reusability & Recycling

The material is easy to recycle, it can simply be melted down and refoamed.
