Solder ( an alloy of Lead and Tin) is used to make fuse wire because of its very low melting point.
Electric fuse wire is not made of a single metal but an alloy made of tin (63 %) & lead (37 %). The cross sectional area determines the melting point at a certain current (amps) and is also rated as volts / rating.
i think an alloy is just when you mix 2 types of metal
metallic element used as an alloy in wheels for classic cars
alloy
Steel is an alloy of iron with carbon and metals as: chromium, vanadium, silicon, etc.
The alloy for sword blades was Damascus steel.
Iron is used for electromagnets.
aluminium alloy
Its light weight and resistnace to coorsion are important factors. The use worldwide differs. Aluminium alloy, coated aluminium wire are used. In the UK aluminium is not recommended for domestic use.
Alloy is a mixture because it is joined physically and not chemically as a compound.It is an mixture of steel,metal and aluminum etc.....
to prevent an unduly high electric current to pass
Stainless steel, gold alloy, nickel/titanuim alloy. source= textbook.
