C3604
(two kinds of excellent cut brass) | C3604 is said to be two kinds of excellent cut brass and is particularly superior in cover cut characteristics with the brass which raised cutting characteristics by adding lead in brass in materials most suitable for cutting in the brass. The feature is that it is easy to cut cut riyasusanokotodeari, the excellent cut brass according to the name of "the excellent cut" with the cover cut characteristics. Even small power is cuttable and can clean a cutting facing and it is minute and can easily separate the chip, too. In addition, superior properties include weldability, plating characteristics. | Parts, gear, valves such as the precision instrument or clock |
