CNC Machining Brass Available Materials
Brass is a popular material for CNC machining due to its machinability, aesthetic appeal, and corrosion resistance. Here are some common brass grades frequently used in CNC machining, each chosen for their unique properties and suitability for different applications:
C36000 Free-Cutting Brass, also known as free-machining brass, is the most commonly used brass alloy for machinable components due to its outstanding machinability and favorable mechanical properties. This alloy typically contains about 61.5% copper, 35.5% zinc, and small amounts of lead (around 3%), which contribute to its excellent machinability.
Key Properties:
- Excellent Machinability: The presence of lead in small quantities acts as a lubricant, significantly enhancing the alloy’s machinability, making it ideal for high-speed machining operations.
- Good Mechanical Strength: While it offers moderate strength, it is sufficient for most machining applications.
- Decent Corrosion Resistance: Offers resistance to corrosion from water and many atmospheric conditions.
Common Applications:
- Precision Components: Widely used for precision instruments such as gauges, clock components, and electronic hardware due to its ease of machining.
- Fittings and Connectors: Ideal for plumbing fittings, electrical connectors, and fasteners where extensive machining is required.
- Valves and Gears: Commonly used in the production of gears, valve components, and other mechanical parts that require detailed shaping.
- Decorative Items: Often utilized for decorative purposes in applications where a smooth, clean finish is desired.
C37700 Forging Brass, also commonly referred to as forging bronze, is a high-quality brass alloy particularly suited for hot forging and pressing. Composed primarily of copper and zinc, with a typical composition of around 58% copper, 39% zinc, and small amounts of lead (around 1.5% to 2.5%), it stands out for its excellent forgeability and good machinability.
Key Properties:
- Excellent Forgeability: The structure and composition of C37700 make it ideal for hot forging, allowing it to be shaped into complex forms without cracking.
- Good Machinability: While it offers superior forgeability, it also retains good machinability, making it suitable for subsequent machining operations.
- Decent Corrosion Resistance: Provides moderate resistance to corrosion, making it suitable for general use in mild environments.
Common Applications:
- Architectural Hardware: Used extensively in door handles, knobs, hinges, and other hardware where aesthetic appeal and mechanical performance are required.
- Plumbing Fittings: Ideal for applications such as faucet components and other plumbing fixtures that require a durable, aesthetically pleasing finish.
- Automotive Components: Applied in various automotive parts where strength and resistance to deformation are necessary during and after forming.
- Valves and Pumps: Commonly used for components in valves and pumps that can benefit from the alloy’s ability to be forged into complex shapes.
C38500 Architectural Bronze, commonly referred to as architectural brass, is a popular copper alloy primarily used for its aesthetic and mechanical properties. This alloy typically consists of approximately 57% copper, 40% zinc, and 3% lead, making it well-suited for extrusion and hot forming.
Key Properties:
- Excellent Formability: C38500 is highly malleable and can be easily formed or extruded into complex shapes, making it ideal for architectural applications.
- Good Machinability: Despite its high zinc content, the presence of lead improves its machinability, allowing for easier cutting and shaping.
- Attractive Appearance: Known for its rich, golden tone, it provides an aesthetically pleasing finish that enhances its use in decorative and architectural applications.
- Moderate Corrosion Resistance: It offers decent resistance to atmospheric corrosion, suitable for indoor and sheltered outdoor applications.
Common Applications:
- Decorative Architectural Elements: Widely used in the fabrication of decorative grilles, window frames, doors, and trims where both strength and appearance are crucial.
- Plaques and Signage: Ideal for creating detailed, durable plaques and signage that feature intricate designs due to its excellent formability.
- Railings and Fixtures: Employed in railings, fixtures, and other structural components in buildings, both for its mechanical properties and its visual appeal.
- Furniture and Hardware: Used in the production of furniture accents, knobs, and other hardware where a premium, decorative finish is desired.
C27000 Yellow Brass, often referred to simply as “Yellow Brass,” is a popular alloy in the brass family, primarily used where high ductility and visibly appealing surface finish are required. Composed typically of approximately 65% copper and 35% zinc, C27000 lacks the lead additives found in other machinable brasses, which influences its properties and applications.
Key Properties:
- High Ductility: This alloy is highly malleable, allowing it to be formed into complex shapes without cracking, making it ideal for deep drawing and forming operations.
- Good Corrosion Resistance: C27000 offers good resistance to corrosion from water and air, making it suitable for various environmental conditions.
- Excellent Cold Workability: It can be easily worked at room temperature, enhancing its suitability for intricate manual adjustments and cold forming.
- Moderate Machinability: While it does not machine as easily as leaded brasses, it still offers reasonable machinability and is often chosen for forming over machining.
Common Applications:
- Decorative Applications: Its bright, golden-yellow appearance makes it suitable for decorative items such as trim, fixtures, and architectural accents.
- Musical Instruments: Used in the manufacture of brass musical instruments like trumpets and trombones where both sound quality and aesthetics are important.
- Radiator Cores: Commonly used in the fabrication of radiator cores and tanks due to its excellent heat conductivity and resistance to rust.
- Cartridge Casings: Historically known as “cartridge brass” because of its use in ammunition casings where its ductility allows for effective reshaping and resizing.
Brass CNC Machining Processes
Brass Turning for Cylindrical Parts
Turning turns brass into precision cylindrical parts, ideal for applications requiring smooth surfaces and tight tolerances, such as shafts and bushings.
Brass Milling for Complex Features
Complex features including slots, contours and intricate geometries are machined into components to produce parts with unique shapes and fine features.
Brass Drilling for Holes
Drilling in brass machining focuses on producing accurate, clean holes, which is critical for parts that require precise hole sizes and locations, such as nozzles and connectors.
Surface Finishing for CNC Brass Parts
- Polishing: In order to make the surface of brass parts as smooth as a mirror, oxides and small surface imperfections can be removed.
- Plating: Nickel, chrome, gold plating
- Passivation: To remove surface contaminants and increase corrosion resistance.
- Powder Coating: Applying a protective and decorative layer that cures at high temperatures to form a skin.
- Anodizing: Improvement of surface hardness and wear resistance through a controlled oxidation process.
- Brushed: Brass is polished with a fine bristle brush on a belt or wheel to achieve a one-way satin finish.
- Bead blasting: brass is sprayed with small beads under high pressure to obtain a uniform matte finish.
- Engraving: Engraving patterns or text on the brass surface with a laser.
