bimetallic thread

Bimetallic wire is a composite wire product with a core and an outer layer made of two different metals or alloys. This material has the characteristics of both the core and the outer material, when used can achieve the purpose of saving high-value metal and can make up for the lack of performance of the main material. Therefore, the application is increasing day by day, especially in the field of high and new technology has been more and more applications.

Bimetallic wire is a new type of material that combines two metals with different properties, overcoming the shortcomings of a single metal, not only utilizing the respective properties of a single metal, but also reducing production costs. Copper clad steel bimetallic wire is a steel wire as the core substrate, through mechanical, metallurgical or electrochemical methods in its surface concentric, uniform, continuous coating of a layer of copper. Copper clad steel bimetallic wire not only has the excellent electrical conductivity and corrosion resistance of copper, but also has the high strength of steel, plasticity, weldability and other good properties.

Copper-clad steel wire is used as a large number of large-span overhead wires. In addition can also be used as capacitors, transistors and other electronic parts of the lead wire and electric vacuum parts. Aluminum clad steel wire is widely used as large span overhead conductor. In addition can also be used as power distribution lines and communication wires. Dumex copper-clad iron-nickel alloy wire is used as diodes, rectifier leads, cathode ray tubes and fluorescent lamps encapsulated line. Copper clad aluminum wire is used as the central conductor of coaxial cables for high frequency circuits. Copper clad stainless steel wire is used in electroplating industry. Copper clad stainless steel wire is used as electrode wire for EDM and core wire for coaxial cable. Aluminum clad steel profile wire is used as the contact wire of optical guide cable and electrified railroad. Copper clad steel profile wire is used as contact wire for high-speed electrified railroads. Nickel-titanium composite wire is used as shape memory alloy wire. Diamond clad metal wire is used for cutting semiconductors and ceramics.

Since bimetallic wires have different coefficients of thermal expansion, they can be used to measure temperature changes. When bimetallic wires are exposed to temperature changes, they bend or twist due to the different coefficients of thermal expansion and can therefore be used to measure temperature changes. This principle is widely used in thermocouples, thermometers and other temperature measuring devices.
