C48600

C48600, recognized as naval brass, finds substantial application in machine hardware, screw machine products, and valve stems. This variant of naval brass, referred to as C48600, emerges as a prime choice for hot forging, pressing, and machining processes. Notably endowed with high ductility, naval brass also exhibits exceptional electrical and thermal conductivity. Additionally, C48600 naval brass demonstrates favorable resistance to creep and impressively high impact strength.
