circuits for melting metals

Why is melting point of fuse low scienceanswersHow to Extract the Gold From Computer Circuit Boards Our

Fuses are used to protect circuits from overload by being the part that fails first To do their job they have to be the weakest link in the chain If they had higher melting points something else instead of the fuse might break first making the use of a fuse quite pointlessGold in these circuits occurs as a layer over a base metal substrate such as nickel or copper Separate the gold plated metal parts in the circuit boards using a magnet Some gold plated parts may be inside ceramic components
