Metals have the low specific heat capacity.why is the low specific heat capacity useful?

Because they are easier to heat up! Think of why your pots, pans, and stove burner coils are metal.

So is that the only use for less heat capacity?

I'm not sure, though I know there are some specific heat considerations for building materials, etc. I suppose an electrical fuse needs to have low specific heat in order to melt, but it already needs to be a metal to conduct the electricity anyway. I'm really not sure about any other specific uses, most of the situations I can think of already require the use of metal for another reason.

The heat capacity of metals per mole is not particularly low (this is due to the Dulong-Petit law), many of them just have a high molar weight, so the heat capacity per mass is lower. It is useful because you need to heat iron for example to 1540 °C to melt it.
