Which string material is best for electric guitar?

The majority of electric guitar strings are made from steel with a coating/plating such as nickel or tin applied, to create a reliable and long lasting string. Electric strings tend to use thinner strings than acoustic guitars.

Do electric guitars need different strings?

Electric guitars have strings made specifically for them. They come in different gauges to suit a variety of guitar scale lengths and styles of playing.

What is the normal string gauge for electric guitars?

The majority of electric guitars are strung with gauge 9 or 10 strings and these gauges are what most guitarists prefer. Gauge 9 is easier on the fingers. Gauge 10 strings are considered by some players to sound better but this is subjective. Guitars with slightly shorter 24.75"" scale lengths work well with gauge 10 strings. As always, experiment a little and find your own preference: there are no hard and fast rules.
