Characteristics and applications of copper-steel clad metals (copper-steel-copper clad metals; steel base aluminum clad metals) (copper-steel explosive welded metals)
With the advantages of anti-corrosion, wear resistance, good electric and heat conductivity, nice appearance, low cost, etc, copper-steel clad metals are used broadly in the field of civil, industrial, and military industries.
In the civil field, with the flatness and surface glossiness, copper-steel clad plate is much better than stainless steel plate on machinability. With its good heat conductivity, it can substitute for stainless steel since its heat transfer coefficient is 3 times of stainless steel. So it becomes the perfect material for solar water heater, frying-pan, electric rice cooker, etc, such heating and heat transfer devices. Copper-stainless steel clad plate or copper-low-carbon steel clad plate can also make cookware since its good heat conductivity, rigid and nice appearance.
In the fields of electronic and electrical, copper-steel clad metals have been widely used instead of traditional copper and copper alloy to make electronic devices. Armor cable used to be made of copper or copper alloy, however, copper-stainless steel clad metals take the place of copper or copper alloy now, not only ensuring the electric conductivity, and corrosion resistance, but also increasing strength, and reducing thickness.
In the metallurgical industry, copper-steel clad metal is used for electroplating, electrolysis electrode, processing electrode for discharge, grounding rod, current conducting arm body, electrode clamp, and an electrode clamping-release device and so on. Copper-steel or aluminum-steel clad metal can be used for bimetal bearing, bearing bush, and liner tube, wear-resistant plate, self-lubricating slide plate, etc.. Copper-steel clad plate can make electrometallurgical furnace and bi-layer water cooling shell & bi-layer crystallizer of melting furnace.
In the military field, copper-steel clad metals can make transmitter, not only solves the leakages, joint corrosion such problems, but also simplifies the manufacturing process, and reduces the cost. If making shells with copper-steel-copper clad metals substituting for brass, it will be much cheaper and much better of ballistic performance.
In the field of machinery manufacture, copper-steel clad metals can make heat exchangers, synchronizer cone rings, reducer worm gears, bearing bushes, etc. Copper-steel and aluminum-steel clad metals can make bimetal or multi-metal bearings, bearing bushes, and liner tubes.
In the field of transportation, copper-steel and aluminum-steel clad plate can be used for linear motor's clad induction plate (copper-steel clad induction plate) on light rail locomotive and subway train. This material not only has good electrical conductivity and good in corrosion resistance, but also improves the strength, and reduces the thickness as well as the cost.
In the field of nuclear power projects, copper-stainless or copper-nickel alloy, copper-low carbon steel clad metals can make nuclear waste storage containers. Big copper-steel clad plate can make linear accelerator cavity for high energy physics research.
In the marine engineering field, copper-steel, copper-titanium clad plate can make offshore oil platform structure which can meet properties of high strength, seawater corrosion resistance.
In the shipbuilding industry, copper-steel clad plate can weld ship parts or warship parts which ensure high strength, seawater corrosion resistance.
