The Zildjian I Family Medium-Thin Crash 17" is a B8 Bronze cymbal with a traditional finish and modern sound characteristics. The overall thinner construction of the Zildjian I Family cymbals results in a more expressive sound with better response and a well balanced basic character. The overtone-rich B8 Bronze alloy (92% copper / 8% tin) of the Zildjian I Family Medium HiHat is machine-hammered and lathed on both sides. The great workmanship combined with the professional sound offers ideal characteristics for beginners and advanced drummers. Like all Zildjian cymbals, the I Family series is made in the USA to professional quality standards.
