Application and Type of Copper Strip Roll

Copper tape (or coil) is a very practical form of metal. There are four main types of copper tape (or coil): pure copper tape, brass tape, bronze tape and nickel silver tape. Pure copper strip has excellent thermal and electrical conductivity, excellent cold and hot processing performance, can be welded and brazed, and has good corrosion resistance; Paint, good corrosion resistance and weldability; bronze strip has excellent cold workability, electroplating, hot dip plating and welding performance, high strength, good elasticity, seawater and process atmosphere corrosion resistance; nickel silver strip also has good cold workability , Good electroplating, hot dip plating and welding performance, high strength, high elasticity, corrosion resistance, fatigue resistance, shielding and other properties.


Ⅰ. Application of copper strip roll


Copper strip rolls are widely used in electronic components, hardware products, radiators, automotive connectors, terminals, semiconductors, buttons, handicrafts, heat sinks, water tank pipes, etc.


Ⅱ. The type of copper strip roll


1. Brass tape


Brass strip is an alloy containing copper and zinc. Uniform color, excellent processing performance, strong deep drawing ability, easy electroplating and painting, good corrosion resistance and weldability. Brass tape is widely used in electronic components, switch sockets, architectural etching, windshields, fasteners, nameplates, labels, condensers and heat exchangers, hardware and clothing, dials, lipstick cases, etc.


2. Tin phosphor bronze belt:


Tin phosphor bronze tape is an alloy containing copper, tin and phosphorus. It has excellent cold workability, electroplating, hot dipping and welding performance, high strength, good elasticity, corrosion resistance to seawater and process atmosphere. Tin phosphor bronze tape is widely used in high-tech electronic fields such as computer CPU sockets, automobile terminals, mobile phone buttons, and electronic connectors.


3. Copper belt:


Copper tape contains at least 99.90% copper. It has excellent thermal and electrical conductivity, excellent cold and hot processing properties, can be welded and brazed, and has good corrosion resistance. Copper strips are used in the manufacture of automotive water tank pipes, radiators, electronic parts, semiconductors, automobiles and electrical appliances.


4. Nickel silver bars:


Nickel-silver ribbon is an alloy containing copper, zinc and nickel. It has good cold working properties, good electroplating, hot dip plating and welding properties, high strength, high elasticity, corrosion resistance, fatigue resistance, shielding and other properties. Nickel-silver tape is widely used in the manufacture of structural parts, elastic components, precision instruments, communications industry, liquid crystal oscillator component shells, etc.


5. Lead frame strip/KFC:


Lead Frame Strip/KFC has high electrical conductivity and strength, good cold/hot workability and weldability. 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 ribbon is an alloy containing copper, nickel and silicon. Has good cold working, electroplating, hot dip tinning properties, suitable for soldering and gas shielded welding. With high yield strength, excellent fatigue resistance and bending performance, it is mainly used in large-scale integrated circuits and other fields, such as stamping parts, connectors, relay springs, semiconductor components, etc.
