In the study, we analyzed the characteristics of bimetal applied in different occasions in low-voltage apparatus industry. The advanced independent constant tension and positioning bonding technology, and the multi-roller precision rolling technology, as well as the special tooling design, were applied to realize the preferential recombination of single metal material layers with different thickness and develop a series of Ni-saving thermal bimetals with good performance and environ-mental protection. Results show that the new bimetals have the characteristics of high welding strength and adjustable resistance, so that they can meet the requirement of low-voltage apparatus to be applied to occasions with different current. Also the nickel can be saved up to 30%. Now the new bimetal product of 192 series has better corrosion resistance, and it can be applied in special environment.
