溴化铝是一种无机化合物，化学式可以表示为Al₂Br₆或AlBr₃。

溴化铝可以由氢溴酸或溴直接和铝反应得到：

2 Al + 6 HBr → 2AlBr₃ + 3 H₂

2 Al + 3 Br₂ → 2 AlBr₃

Aluminium bromide is any chemical compound with the empirical formula AlBr_x. The species called "aluminium tribromide," is the most common aluminium bromide. The species aluminium monobromide forms from the reaction of HBr with Al metal at high temperature. It disproportionates near room temperature:
