Wire for use in the automotive and aircraft industries
Product category: Wire rod
The first stage of the production process is fire refining and anode casting process. Raw material of this process is blister copper, copper ingots and scrap copper. Fire refining takes place in THOMAS type furnaces at about 1250 oC. Refined molten copper which has 99.5% copper purity is poured into anode molds with a tolerance of ± 1 kg by using PLC controlled automatic casting system.
The second phase of production and refining process is electrolysis. Electrochemical technique is applied to cast anodes with the purity of 99.5% Cu. Copper purity after electrolysis is 99.99% which is called as high grade electrolytic copper. Precious metals such as gold and silver go into anode slime. These metals are extracted from anode slime by using further processes.
Electrolytic copper cathodes are melted in the atmosphere controlled shaft furnace, and transferred into the holding furnace and Hazelett casting machine via the launders. With the assistance of automatic metal feeding and level control system, copper bar is continuously cast and then rolled to 8 mm (5/16") standart wire rod by hot rolling mill running in synchron. Following to hot rolling, the wire rod passes through the pickling line for surface de-oxidation, cooling and brighthening, and then is packed into coil form to be ready for shipment.
SARKUYSAN is located in Gebze on 180.000 square meters and with covered area of over 77.000 square meters where electrolytic copper products,copper tubes,busbars and copper alloys are produced.SARKUYSAN increased annual production capacity to over 220.000 tonnes which was 10.000 tonnes at the inital stage. SARKUYSAN's products are the standard input materials of several industries including electro technique,electronic,motor,communication,power generation and distribution, solar and renewable energy,home appliances, measurement instruments, defence, automotive, chemical, construction,heating, air-conditioning and sanitary plumbing. With "sks" trademark products,SARKUYSAN is the leader in its sector. Exports a significiant portion of its products to nearly 70 countries in five continents. It's estimated that almost half of the autos and commercial vehicles produced in Europe use Sarkuysan's wires.For many years the company has been selling oxygen free and nickel plated copper wires to the suppliers of NASA and in recent years to aerospace industry.
SARKUYSAN also produces enamelled copper wire with “BMK” trademark with production capacity of 25.000 tons/year .
