Aluminium alloy - Wikipedia

Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.There are two principal classifiions, namely casting alloys and wrought alloys, both of which are further subdivided into the egories heat-treatable and non-heat-treatable.

Gallium nitride - Wikipedia

Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure.Its wide band gap of 3.4 eV affords it special properties for appliions in optoelectronic, high-power and high-frequency devices.
