    Small amounts of aluminum carbide are a common impurity of technical calcium carbide. In electrolytic manufacturing of aluminum, aluminum carbide forms as a corrosion product of the graphite electrodes. In metal matrix composites based on aluminum matrix reinforced with non-metal carbides (silicon carbide, boron carbide, etc.) or carbon fibres, aluminum carbide often forms as an unwanted product. In case of carbon fibre, it reacts with the aluminum matrix at temperatures above 500 °C; better wetting of the fibr
