Heyy mate..here is the answer..
.
.
Alloys generally have higher resistance than the pure metals that they are made of, because the alloy disorder of the atoms causes additional electron scattering. Nichrome - which is an alloy of nickel and chromium, is usually a good choice.
hope it helps...thnku..nd good ni8

1.because it's resistivity is higher than that of pure metal.
2.an alloy doesn't undergo oxidation(or burn)easily even at high temp,when it is red hot
