    current density of copper ?

    The copper is a better conductor than Al, because your resistance specifie is smaller. Cu=0,0176 ohm * cm. Al=0,028 ohm * cm. The resistance is :ohm*cm*L/S. The Loose are:I*I*R and they become heat. Coefficient of temperature for grade Celsius: Al=0,0044 Cu=0,0043. Regards. Hugo.
