How we can service the electronics industry
Copper is widely used in electronics due to its high degree of conductivity mainly as electrical wiring; both from power sources to outlets and from outlets to electrical appliances. Copper can also be found in CPU heat sinks, printed circuit boards and computer chips. Silver although a precious metal is also often used, it is a better conductor than gold with a conducting rate of 63,010,000 ohms per meter of wiring. It’s thermal and electrical conductivity is unsurpassed by other metals, meaning it cannot easily be replaced by less expensive metals. It is often used in printed circuit boards, computer chips, electrical switches, keyboard membranes and some capacitors.
Nickel can be found in some circuit board components, cobalt is used in hard drives and when alloyed with silicon is also found in integrated circuits, it has a low resistivity and high thermal stability. Aluminium can be found in circuit boards, computer chips, hard drives and CPU heat sinks, tin in circuit boards and computer chips and zinc in printed circuit boards. Tungsten was widely used in light bulbs however; they are generally being phased out with the introductions of LEDs which use gallium, indium and rare earth elements instead.
Metal powders, mainly copper are used within carbon brushes. Their interlocking characteristics provide ideal conductivity along with strength. Carbon brushes for domestic and industrial applications are produced using this technology. Metal powders such as silicon and aluminium can be incorporated within re-chargeable batteries.
