Bubble Metal

From Earth Central

“	Bubble Metal: These materials were first developed by the Cryon Corporation in 2110. The process of manufacture is simple. A base metal (or alloy) is pured into null-G moulds (hence their development in the first satellite factories) and, while still in a molten state, injected with gas (usually inert). The resultant 'foamed metal' is then allowed to cool. Components made by this process are usually high in compressive and tensile strengths, but are prone to corrosion. Further developments brought us anti-corrosive gases and ceramoplastic injectants. This technology has become widely applied, the only solidcast components now being those used in electronics applications, where the crystal structure or purity of the metal is a requirement.	„
