The invention relates tometallurgy, in particular to alloys based on copper with set electrical conduction, which are used for production of coins and in electrical engineering. An alloy contains, w/w: zinc – 14-16, aluminium – 0.9-1.1, tin – 0.9-1.1, manganese – 0.4-0.8 and copper – the rest. Technical result: obtaining of alloy with specific electrical conduction of 17.8±0.4 % IACS providing a certain recognition of coins or counters in vending machines and devices of bank equipment. |
