Notes:

1. By agreement with the consumer allowed to Marche Nmc2,5 the content of iron not more than 0.4%, copper not more than 0.20%, sulphur less than 0.015% carbon and not more than 0.10%; in the Marche Nmc5 — content of copper not more than 0.20%, sulphur less than 0.015% carbon and not more than 0.15%.

2. The asterisk indicates the alloys used in legal relations on cooperation.

3. Mass fraction of cobalt in the alloys Nmc1, Nmc2, Nmc2,5, and Nmc5 should not exceed 0.5%.

4. In alloys Nmc1 and Nmc2 mass fraction of carbon should be not more than 0.05%.

5. Total mass fraction of volatile impurities lead, zinc, cadmium, arsenic, antimony, bismuth and phosphorus in alloys Nmc1 and Nmc2 shall not exceed 0.008%, including mass fraction of zinc 0.002%.

6. The grades NH9,5 and NH9 in new developments is not recommended.

Notes:

1. By agreement between manufacturer and consumer in the brand Mngmt 30−1-1 carbon content shall not exceed 0,03%.

2. For grades MN19, MN25, Mnzhmc10−1-1, Mnzhmc30−1-1, MNZH5−1, MNC12−24, MNC15−20, MNC18−27, MNC18−20 due to the Nickel content allowed the content of cobalt up to 0.5%.

3. The alloys MN25, Mnzhmc10−1-1, MNC12−24, MNC18−27, MNC18−20 in agreement with the user can determine the content of impurities of silicon, magnesium, arsenic, bismuth, phosphorus, tin, antimony.

4. In coordination with the consumer in the alloys of MN19, MNC15−20, Mnzhmc30−1-1 may be determined by the contents of the tin.

5. The characteristic properties of the alloys are given in Appendix 2.

(Changed edition, Rev. N 1, 2, 3, 4).


3. The cupronickel MN19 brand used for the manufacture of coins allowed a higher content of manganese or iron is more than indicated in table.3, but the sum should not exceed 1.3 percent. The cupronickel MN19 brand used for the manufacture of tapes for special purposes, the following impurities: manganese, not more than 0.01%, magnesium not more than 0.01%, silicon not exceeding 0.15%, iron not more than 0.3% and sum of impurities not more than 0.6%.

4. The Constantan brand Mnmc40−1,5 used in electronics, the zinc content shall be not more than 0.03%.
