Hub for annealing multi-wire resistance An annealer machine

For multi-wire resistance annealer machines, contact tubes or nickel tubes are extremely worn components.

 Our tubes are made of 45# steel tube coated nickel, which has a thickness of up to 3mm. This reduces machine downtime and endurance, lowers maintenance costs, and reduces some unique dangers.

 In the meanwhile, our products are available in several sizes upon customer request and fit Frigeco, Niehoff, Samp, Sictra, Henrich, and Eurodraw, among other wire machines.

 An affordable substitute for solid nickel tubes are nickel contact hubs (tubes).
