Each casting is cooled and sorted by weight for each cymbal model, then the castings are put through a complex sequence of heating, rolling, shaping, hammering, and lathing techniques unique to each cymbal range. Cast Bronze cymbals have a rich, full-bodied sound that improves with age, and have greater projection, clarity and durability than any other cymbals. Zildjian cast cymbals are made from the Zildjian secret alloy, which is comprised of 80% copper, 20% tin, and traces of silver. What"s in the Box 20-inch Zildjian A Custom Medium Ride Cymbal
