Brass, an alloy of copper and zinc, is ductile, highly corrosion-resistant, polishable, and an accessible material. These properties make brass a versatile metal for machining parts.
Brass for CNC Machining
As a widely used alloy material, brass is commonly used in various fields, especially in CNC machining, because of its good machinability, corrosion resistance and mechanical properties. There are many models of brass, but not all of them are suitable for CNC machining. Below, I will list some brass models ideal for CNC machining and explain their characteristics and why they are suitable for machining.
Copper Alloy 260 (Brass 260)
- Characteristics: Also known as 70-30 brass, containing 70% copper and 30% zinc, with good cold working properties.
- This material’s flexibility and cold working properties are excellent, ideal for manufacturing precision cold working parts, such as radiators and decorative parts.
C360 Brass
- Characteristics: C360 brass has excellent machinability due to its high lead content. This alloy has good corrosion resistance, moderate strength, and superior welding and forming capabilities.
- C360 brass is ideally suited to CNC machining, especially in applications that require high-speed cutting and the formation of fine features. Its excellent cutting properties mean higher machining speeds can be achieved without sacrificing surface quality, resulting in significant productivity gains. In addition, C360 brass excels in manufacturing complex shapes and precision parts such as electronic parts, small gears, valves, fittings and more.
H62 Brass
- Characteristics: H62 brass contains 62% copper. The rest is zinc and trace elements. It has good mechanical properties and thermoplasticity, as well as high strength.
- Because of its good plasticity, it is suitable for hot and cold processing, especially excellent processing performance on CNC lathes, which makes it ideal for creating complex shaped parts.
C28000 (Muntz metal)
- Characteristics: It contains about 60% copper and 40% zinc and has good strength and corrosion resistance.
- Its mechanical properties and corrosion resistance make it suitable for machining marine and chemical equipment and CNC machining. It is particularly suitable for machining parts that require a certain degree of strength and corrosion resistance.
Finishing and post-processing technology of brass
Polishing
Removing minor surface depressions and imperfections by physical or chemical means enhancing the part’s lustre. Polishing can be categorized into mechanical polishing, electrochemical polishing, etc. The purpose is to obtain a smooth surface.
Plating
Plating the surface of brass with a layer of other metals or alloys, commonly used plating materials including nickel, zinc, chromium, etc., to improve the corrosion resistance and appearance of the parts. Plating can also provide additional resistance to wear.
Cleaning
Removal of grease, stains and oxides that may have been generated during processing. Cleaning is usually the first step in post-processing, ensuring the part’s surface is clean and ready for subsequent processing.
Colouring or Coating
Forming a thin film on the surface of brass by chemical or physical means to change its colour or increase corrosion resistance. Common treatments include colouring and anodizing to give the part more decorative and protective qualities.
Heat Treating
Altering the microstructure of brass through heating and cooling processes to increase its hardness and strength or improve its other mechanical properties. Heat treatment can increase the durability of a part.
Sandblasting or Beadblasting
Cleaning and roughening surfaces by spraying sand or tiny beads at high speeds to improve coatings adhesion or achieve a specific surface texture.
Etching
Chemical solvents are used to locally etch the surface of a part to create patterns, text, or other decorative effects.
