Al and C do not form a thermodynamically stable compound.

Carbon may occur infrequently as an impurity in aluminum in the form of oxycarbides and carbides, of which the most common is Al4C3, but carbide formation with other impurities such as titanium is possible. Al4C3 decomposes in the presence of water and water vapor, and this may lead to surface pitting.
