AJ alloys explained

AJ alloys (AJ52 and AJ62) are die castable alloys of magnesium that have good creep resistance at high temperature. They contain magnesium, aluminium, and strontium.[1]

In the names the 'J' refers to Strontium.

AJ52 has higher creep resistance, and AJ62 has better castability. Both are used in the BMW magnesium–aluminium composite engine block.[4]
