Contact hube or nickel tubes are highly wear parts for the multi-wire resistance annealer machines.

Our hubs with materials 45#steel tube coated nickel, the thickness of the nickel up to 3mm   which leads to lower endurance and machine downtimes , drop the machine .maintenance and minimize some special other risks.Our nickel coated steel hubs are with competitive prices alternative to solid nickel tubes.

Our products fit Frigeco/ Niehoff/ Samp/ Sictra/ Henrich/ Eurodraw and other wire machines, meanwhile, in various dimensions for customer request.
