Advantage of our oxygen free wire rod is in its high conductivity because of absence of impurities and inclusions. That is why production that is made from oxygen free wire rod has better characteristics of electric resistance. Corresponding to above mentioned it gives a possibility to reduce the weight of wire or core as a result of wire diameter reducing, herewith such requirements of GOST as electrical DC resistance remains relevant. High producibility of our wire rod, that is achieved as a result of absence of oxygen compounds in copper, allow to exclude the process of mean drawing and receive fine wire with diameter 0,15–0,5 mm without interstage annealing. Oxygen free wire rod recycles to the wire with diameter 0,15–0,5 mm without breakages and on high speeds. It reduces the expenses for further manufacturing.
Coils of copper wire rod that have weight from 1000 to 3500 kg are packed on wooden pallets and covered with PE film, fixed with steel straps.
Guaranteed storage life of wire rod: three months from the date of manufacture.
