Chemistry:AJ alloys
From HandWiki
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.
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–aluminium composite engine block.[4]
