What other metal are use in computers?

Answer 1

Hey... why do u need metal used in computers.... Computers need no metal... It's building blocks are the semiconductor devices like Microprocessors, I/O interface ICs, Interrupt ICs and so on... But yet if you want to know the metal used in desktop... I can help u... They are simply the iron.... try them with your magnet... They get well attracted..... This metal is for casing your desktop.... Needless to say,, the casing can be of anything dude!

Answer 2

Gold - it's used as the internal wiring in micro-chips. However - there's not enough gold in computer chips to make it worthwhile dismantling the chips to get at the metal ! We're talking about micro-grammes !

Answer 3

The case itself will use some steel (iron alloy) and perhaps aluminum. The solder on the circuit boards will be a mixture of tin and lead (usually 60% tin and 40% lead), and sometimes silver is added to solder for specific applications. The circuit board traces are usually copper, though plastic connectors and keyboards may use carbon traces. It will contain metalloids including germanium and silicon. It may contain alkali metals such as lithium, at least in the CMOS battery. It may contain transition metals nickel and cadmium, particularly in the case of laptop batteries and batteries of palm computers (may contain just nickel and other transition metals). There may be tantalum capacitors. Gold may be used in CPU contacts and internal traces. Mercury would be used in cold cathode lamps, including decorative PC lighting and LCD monitors. Gadolinium is used as green phosphors in CRT monitors and CDs, and sometimes in nonvolatile memory (bubble memory).

Maybe it would be better to have a table by metal and application:

• aluminum - hard drive, rivets holding the case together, capacitors
• cadmium - batteries, CRT monitor
• carbon - some internal ribbon connector traces such as in laptops
• copper - circuit boards
• gadolinium - CRT monitor, CDs, memory
• germanium - semiconductor used in chips, transistors, and diodes
• gold - semiconductor contacts and traces
• iron - case, brackets, screws, and the hard drive.
• lead - solder, CRT monitor, may also be used in glass
• lithium - batteries
• mercury - lighting and monitors (perhaps both LCD and CRT)
• nickel - batteries, magnets, could be some in the case
• silicon - semiconductor in chips
• silver - soldering or contacts
• tantalum - capacitors
• tin - soldering, Li-ion batteries
• zinc - screws

Answer 4

It's impossible to know exactly but copper steel gold and aluminum are common.

Answer 5

gold and copper ...
