Common Types of Brass for CNC Machining

  1. Brass C260 Brass C260, commonly known as cartridge brass, consists of 70% copper and 30% zinc. This alloy is highly ductile and widely recognized as a versatile option for CNC machining due to its general-purpose nature.
  2. Brass C360 Brass C360 stands as the industry standard for CNC machining and high-volume production. Renowned for its exceptional machinability, C360 brass enables the full utilization of screw machine capabilities, making it an ideal choice for CNC machining applications.
  3. Brass C46400 (Naval Brass) Brass C46400, also known as Naval Brass, is highly regarded for its suitability in CNC machining applications. With a composition typically comprising 60% copper, 39.2% zinc, and 0.8% tin, Naval Brass offers excellent corrosion resistance, making it ideal for marine environments. Its machinability characteristics allow for precise and efficient CNC machining processes, catering to the demands of various industries.
  4. Brass C48500 (High Leaded Naval Brass) Brass C48500, classified as High Leaded Naval Brass, is prized for its exceptional machinability and corrosion resistance. Composed of 60% copper, 38% zinc, and 2% lead, this alloy demonstrates enhanced cutting properties, facilitating smooth CNC machining operations. Its high lead content contributes to improved chip formation and reduced tool wear, ensuring high-quality and cost-effective production for CNC machined components.
