Xiulurium is a “stealth” armor that lacks protective value and is used to generate a stealth field around the vessel that renders most forms of active sensors ineffective against the starship. This stealth field generated by Xiulurium also masks the vessel's presence to scalar wave and quintessence differentialometer type sensors and blocks aether waves and interference with aether waves. Xiulurium is similar to Zanarium in composition, but this alloy is more flexible, requires less energy (to use its stealth), and has only negligible protective value.
Xiulurium is similar to Zanarium in composition, but this alloy is more flexible, requires less energy (to use its stealth), and not as armor-beneficial (easier to puncture/evaporate).
The Yamatai Star Empire considers Xiulurium a restricted material and doesn't export it or allow its export. Only “Major Corporations” are allowed to make and use it under Yamataian law.
