Gallium is slightly smaller than aluminium
WebAlGa (Aluminum-Gallium) is a degenerate alloy that results from liquid gallium infiltrating the crystal structure of aluminium metal. The resulting alloy is very weak and brittle, being broken under the most minute pressure. The alloy is also chemically weaker, as the gallium inhibits the aluminum from forming a protective oxide layer.. Uses. The alloy can be … WebJan 7, 2024 · Gallium has an orthorhombic crystal structure (CN = 6) whereas as aluminum has a face-centered cubic crystal structure (CN = 12).
