Introduction of different kinds of high-precision copper belt

1, high precision zinc white copper strip

White copper alloys are alloys containing copper-nickel alloys and zinc in varying proportions, but without silver. Refers to the color of the alloy. Zinc white copper strip is bright silver white, with good workability, magnetic shielding, corrosion resistance and high elasticity. High precision zinc white copper strip is widely used in crystal resonator shell, mobile phone shielding cover, glasses frame, optical instruments, silver, jewelry, zippers and keys, Musical Instruments and coins, etc.

2. Copper belt for high precision lead frame, LED lead and IC lead frame

Three different types of alloys form three main series of copper strips for lead frames: copper-iron-phosphorus alloys, copper-nickel-silicon alloys and copper-chrome-zirconium alloys. Copper tape for high precision lead frame has high electrical and thermal conductivity, high strength and corrosion resistance. Copper, iron and phosphorus alloys are representative of the two, but also commonly used. High precision lead frame uses copper strip as the basic raw material for manufacturing integrated circuits, semiconductor discrete devices and LED lead support, mainly used in integrated circuits, large and medium power tubes, light-emitting diodes and triodes.

3, high precision brass plate belt

Brass is a copper alloy containing copper and zinc. It is a widely used high-precision copper alloy. Brass has excellent mechanical properties, physical properties, high electrical and thermal conductivity and corrosion resistance.

High precision brass strip is widely used in electronic, telecommunication equipment and household appliances connectors and accessories, interior decoration, clothing accessories, car water tank.
