Beryllium does not form any compounds with aluminum. Instead, it forms a series of alloys whose melting points vary from the melting point of Be (1283 °C) to that of Al (654 °C).However, the melting point line of Be 1-x Al x is not linear but is an "s-shaped" curve as shown in the following diagram. There is a eutectic at 3.1 mol% Be (Be 0.031 Al 0.969) of …Web
