You can see springs almost anyplace you go. Everything from cars to household appliance use springs. Kids toys have springs; even the toy kitchen I bought for my daughter this past Christmas has springs. What kind of wire do they use to makes springs? Well music wire is used to make springs. It is normally made from high-tension carbon that gives it the right quality to makes springs. Music wire is not only used to make springs, but yet piano wire for piano strings is a type of music wire. So now you know as much as I do, that small spring you see may be made of music wire.
