This property is normally only possible with lugs made from aluminum since the coefficient of expansion for the aluminum wire and the aluminum lug is the same, the aluminum wire is durable under heat cycling tests (UL486) which represent accelerated age testing of normal life cycle conditions.  

Years of testing has shown that copper wire in aluminum lugs is also UL 486 durable, making aluminum lugs the universal wire and cable lug material for all common wire types and materials.
