Copper strip roll is a very practical metal form. Copper strip roll is widely used in the production of electronic components, radiators, automotive connectors, terminals, semiconductors, heat sinks, etc.
Types of Copper Strip Rolls
Copper strip rolls are mainly divided into four types: pure copper strip, brass strip, bronze strip and nickel silver strip.
1. Brass strip: Brass strip is an alloy containing copper and zinc. It has uniform color, excellent processing performance, strong deep drawing ability, easy electroplating and painting, good corrosion resistance and weldability. Brass strip is widely used in the production of electronic components, switches and sockets, condensers and heat exchangers, etc.
2. Tin-phosphor bronze strip: Tin-phosphor bronze strip is an alloy containing copper, tin and phosphorus. It has excellent cold processing performance, electroplating, hot dipping and welding performance, high strength, good elasticity, and resistance to seawater and atmospheric corrosion. Tin-phosphor bronze strip is widely used in high-tech electronic fields such as computer CPU sockets, automotive terminals, mobile phone buttons, and electronic connectors.
3. Pure copper strip: Pure copper strip contains at least 99.90% copper. It has excellent thermal and electrical conductivity, excellent cold and hot processing performance, can be welded, brazed, and has good corrosion resistance. Pure copper strips are used to manufacture automotive radiator pipes, radiators, electronic parts, semiconductors, automobiles, electrical appliances, etc.
4. Nickel silver strip: A kind of copper strip material with nickel as the main alloy, which is also widely used in the market.Three elements such as zinc, manganese and aluminum are added on the basis of nickel alloy to form white copper bar, so it is also called zinc white copper bar, manganese white copper bar and aluminum white copper bar accordingly.
Nickel alloy has good corrosion resistance and moderate tensile strength, high plasticity, can be used for cold and hot pressing processing, and has good electrical properties, in addition to used in the production of structural materials, is also an important high resistance and thermocouple alloy. The white copper strip rolls mainly has the following five kinds: ordinary white copper strip, iron white copper strip, manganese white copper strip, zinc white copper strip and aluminum white copper strip.
White copper plate belt also has high corrosion resistance, belongs to the medium strength, high plastic change, suitable for hot and cold pressing process, good electrical properties, in addition to the application of structural materials, but also can be used in high resistance and thermocouple alloy.
5. Lead frame strip/KFC: Lead frame strip/KFC has high conductivity and strength, good cold/hot processing and weldability. It is mainly used in discrete components, IC lead frame materials, LED lighting, relays, terminal connectors, BGA substrate heat dissipation, dispersion materials and connectors, etc.
6. Copper nickel silicon strip: Copper nickel silicon strip is an alloy containing copper, nickel and silicon. It has good cold processing, electroplating, and hot-dip tinning properties, and is suitable for brazing and gas shielded welding. It has high yield strength, excellent fatigue resistance and bending properties, and is mainly used in large-scale integrated circuits and other fields, such as stamping parts, connectors, relay springs, semiconductor components, etc.
Packaging of Copper strip Coils and rolls
Since the price of copper tape rolls is very high, the packaging of copper strip rolls is also very important. We need to consider the large size and overweight of the copper strip rolls, and also need to ensure the protection and reliability of the packaging. Relatively speaking, wrapping the copper strip rolls with materials such as wrapping film and braided tape is the best packaging solution. The packaged copper rolls can be effectively protected from dust and moisture contamination. At the same time, the tight wrapping also ensures that the copper rolls are not easy to unwind, and the surface is not easily scratched during transportation and storage.
