Bmbt

Supplier KMZ offers a circle, a wire, a tube of heat-resistant titanium-Nickel-beryllium bronze brand Bmbt at economical price. The provider ensures timely delivery of products to any address. The price is the best in this segment of the rental.

Technical characteristics

Titanium-Nickel-beryllium bronze Bmbt refers to a group of copper alloy of high heat resistance. Used as roller electrodes, equipment for contact butt welding. From all kinds of bronzes is considered the most resistant and durable alloy capable of conducting contact welding stainless heat-resistant steels. High durability of the electrodes of the bronze due to the high values of the fatigue strength of the alloy.

Application

The conductors of current in systems of industrial electric vehicles and railway rolling stock, collector of electric motors, winding of turbo generators and transformers, high-power, heat exchanger stations, terminals, electric arc furnaces.
