brassmasisasium

Brassmasisasium is a fictional metallic alloy described in speculative science and science fiction. It functions as an enhanced brass alloy formed by combining a copper-zinc base with a hypothetical intermetallic phase called masisasium. The term fuses brass and masisasium to signal a material designed for improved high-temperature performance and corrosion resistance. Because it is not recognized as a real element or alloy, details vary by source.

Most depictions describe brassmasisasium as consisting primarily of copper and zinc, with trace additions of masisasium that form a dispersed intermetallic within the brass matrix. Reported properties include higher yield strength and creep resistance than ordinary brass, good ductility, and improved oxidation resistance at moderate high temperatures. Electrical conductivity is often described as relatively high, and the coefficient of thermal expansion is similar to brass. The exact values differ across fictional descriptions.

Manufacturing in these works involves advanced smelting, controlled diffusion, and rapid solidification to integrate the masisasium phase within the brass matrix. The process is portrayed as requiring specialized furnaces and protective atmospheres.

In fiction, brassmasisasium is used for aerospace fasteners, heat exchangers, and ornamental components where strength and corrosion resistance are valuable. It also appears in speculative devices designed to operate across wide temperature ranges. As a fictional material, there is no real-world hazard profile beyond typical metal powders in fictional contexts. See also brass, alloys, intermetallics.
