Cartridge Brass - Copper 260

Cartridge brass, or Copper 260 as it is sometimes known, is a popular material for CNC machining due to its strength and excellent machinability. It is corrosion-resistant and has superior electrical conductivity, making it ideal for automotive components, electronic hardware, and many other applications. With its impressive strength, high heat resistance, and good machinability, Copper 260 is an excellent choice for precision CNC parts.

CNC Finishes

Brass Finishes and Post-Processing Options

We offer various finishing options for CNC machined parts.

Electroless nickel plating: This coats the part with a nickel-phosphorous alloy, making it corrosion and wear-resistant.

Anodizing: This creates an oxide layer on the surface of the brass part, allowing for a variety of color options.

Zinc plating: This coats the surface of the brass part in zinc, providing protection from rust and wear.

Powder Coating: this coats the part with a layer of polyester or epoxy powder, providing a durable finish.

Black oxidizing: This is a chemical treatment that creates a dark finish on brass components.

Chromate conversion coating: Adds a thin layer of corrosion protection and an attractive finish.

Passivation: A chemical treatment that removes impurities from the surface of the brass.

Hot dip galvanizing: A process in which the brass is dipped into a vat of molten zinc, which forms a protective layer on the surface that prevents rust and corrosion.

Our coating processes are designed to comply with the highest standards of quality and safety, and we use only certified materials that meet or exceed industry standards.
