Typically, a new steel needle is required for every record played on an old acoustic phonograph. This is because the record contains abrasive material. In the first few silent tracks this abrasion hones the steel needle to a profile that tracks the grooves properly. The needle continues to wear as it plays the record, so that by the end its diameter has increased to the point where the sharp edges may damage the grooves on subsequent plays.Tungsten wire phonograph stylus have high hardness to decrease the wear.
