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

In the names the 'J' refers to Strontium.

Alloy   Mg     Al%  Sr%  Mn% 
AJ62  Balance  6    2    0.34   [2]
AJ52  Balance  5    2    0.4    [3]

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