^a Maximum impurities in ppm for C10100 are: 4 antimony, 5 arsenic, 1 bismuth, 1 cadmium, 10 iron, 5 lead, 0.5 manganese, 10 nickel, 5 oxygen, 3 phosphorus, 3 selenium, 25 silver, 15 sulfur, 2 tellurium, 2 tin and 1 zinc.

^b C10400, C10500, and C10700 are oxygen-free coppers with the addition of a specific amount of silver. These alloys have compositions equivalent to C10200 plus the intentional addition of silver.

^c C11300, C11400, and C11600 are high-strength electrolytic coppers with silver additions. Their compositions are equivalent to C11000 plus silver.

^d UNS number 12300 copper is produced by adding silver to phosphorus-deoxidized copper.

^e Copper content shall be determined by the difference between total impurities and 100%.

^f Includes phosphorus.

^g Includes tellurium + tin.

^h Includes tin + tellurium + selenium.

ⁱ Minimum silver values in troy ounces per avoirdupois ton (1 oz/ton = 0.0034%).

^h Tellurium or selenium, or both.
