The aluminium alloy and temper used for the outer strands in the United States and Canada is normally 1350-H19 and elsewhere is 1370-H19, each with 99.5+% aluminium content. The temper of the aluminium is defined by the aluminium version's suffix, which in the case of H19 is extra hard.
A single insulated conductor in free air has 70 A rating. Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. Electrical code rules will give ratings for wiring where short-term loads are present, for example, in a hoisting motor.
Aluminum wire used before the mid-1970s had a somewhat higher rate of creep, but a more significant issue was that the same high price of copper driving the use of aluminum wire led to the use of brass-coated steel rather than solid brass screws for terminations at devices such as outlets and switches.
IEC 60055 Paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables) IEC 60059 IEC standard current ratings; IEC 60060 High-voltage test techniques; IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.
