Naklad 100 egz Cena 130 zl PLThe subject of the invention is a copper alloy of arber-white color, with high resistance to corrosion and abrasion, and good workability on top and cold, especially for making coins as well as other products such as metal accessories, badges, plaques * Among the known materials for coins, having a silver-white color, the most commonly used are copper-nickel alloys, including, known from the Polish standard PN-78 / H-87052, the Cu Vi 25 alloy containing copper by weight: 24 - 26% Ni and 0.1 - 0.5 / * Mn, An alloy for coins with the symbol C754OO is also known from the ASDi standard, containing by weight: 63.5 - 66.5% Cui 17-29 Zn, patent P * 24171? (BUP 23/64) a copper alloy is also known, containing by weight * 29-31% Zn, A, 5-5% Ni and 0.05-1% Mn. The Cu N125 alloy is prone to gassing during the melting and casting process, while the C75400 alloy has a relatively low corrosion resistance, and the copper alloy known from patent application P. 241717, due to its color, is only suitable for the production of low-carbon coins. According to the invention, the copper alloy contains 14 - 16% by weight of Ni, Zn and Mn, characterized by the fact that it contains 6 - 8% of Zn and 0.6 - 1.2% of Mn, the rest being copper. The content of Mn is 0.6 - 0.6% by weight. The alloy according to the invention is characterized by a good workability of salt to the top and to the cold, it can be cast both statically and also in a semi-continuous and continuous process * The properties of the alloy in the recrystallized state are as follows : RQ 2 = 136 - 246 MPa, Rffi = r 367-403 MPa, A10 = 25 - 37%, HV1Q below 95. The following is an example of an alloy according to the invention * Example * Copper alloy contains by weight: 15% Ni, 7% Zn, 0.6% Mn, the rest is Cu * The obtained alloy retains for a long period of time aesthetic, free from dirty coating * 2 138 423 Claims 1.
