Copper clad steel wire, tinned features

Tinned copper clad steel wire is what we often say steel wire, copper clad line "CP", non-ferrous metals prices in recent years as the market continued to rise, copper, aluminum prices, soaring new products emerged. This is copper wire of "replacing" products, are generally divided into soft state (A) blade (H) and two types. Copper plated steel wire, tinned wire is high quality low carbon steel wire, through the use of mechanical means uniformly coated layer of oxygen-free copper and then coated with a (usually divided into cold plating, Redu) pure tin sheet of new composite materials. Because each cover (plating) selection with a high level of purity, between copper coating and the steel core, copper and tin coating layer compact.

Tinned copper clad steel wire is copper, high conductivity, permeability and steel wire high tensile, flexural strength and thermal conductivity, corrosion resistance, and there is some resistance to oxidation at high temperatures. Also, as has excellent resistance and weldability, flexural strength, firmly point welding, its impact resistance of copper wire 3-6 times, ease of automation. It is widely used in electronic components and cables, jumpers souls of RF cables, and has become the communications, electronics, electrical industry ideal conductor.

Copper clad steel wire, tinned features:

(1) low price: the generic price copper copper-clad copper wire current price is only about 1/2 to 1/3.

(2) having a high strength and high toughness steel: tinned copper copper-clad steel, easily cut shape, suitable for all Assembly processes and automated production processes tensile 2 times higher than normal copper wire, coefficient of linear expansion.

(3) light: lighter than copper wire 13%, wire size, equal weight, 1.13 times the length of Tin-plated copper.

(4) has good weldability: 4 hours steam aging, 150 ℃ high temperature for 16 hours still good weld after ageing.

(5) the appearance of smooth: unexposed copper, Tin off, dark spots, corrosion, cracks, pond, defects, and there is no difference between a copper look ordinary.

(6) with excellent high frequency properties. For the combined effect will be increased with increasing frequency, then the conductivity is comparable to the wire section copper cables at high frequencies.
