Among the most widely used materials, C360 brass (Free-Cutting Brass) stands out for its excellent machinability, corrosion resistance, and electrical conductivity. At PuKong CNC Machining, we specialize in high-precision machining of C360 brass components, delivering superior quality parts for industries that demand reliability and precision.
This article explores the applications, material properties, environmental suitability, machining tolerances, and durability of C360 brass, while highlighting PuKong CNC Machining’s expertise in producing high-quality brass components.
Applications of C360 Brass in CNC Machining
C360 brass is a lead-alloyed free-cutting brass known for its ease of machining and excellent mechanical properties. It is widely used in industries such as:
1. Electronics & Electrical Components
- Connectors, terminals, and switch components due to high electrical conductivity.
- Shielding parts and precision contacts in circuit boards.
2. Plumbing & Fittings
- Valve bodies, faucet components, and pipe fittings due to corrosion resistance and pressure tightness.
- Dezincification-resistant variants for water applications.
3. Automotive & Aerospace
- Fuel system components, bushings, and hydraulic fittings.
- Wear-resistant and low-friction parts for mechanical assemblies.
4. Medical Devices
- Surgical instruments and dental components requiring smooth finishes and sterilization compatibility.
5. Consumer Goods & Hardware
- Decorative fixtures, locks, and fasteners due to its aesthetic appeal and durability.
Material Properties of C360 Brass
C360 brass offers an outstanding balance of machinability, strength, and corrosion resistance:
1. Machinability (Best in Class)
- Rated 100% machinability (compared to free-cutting steel as a benchmark).
- Produces smooth finishes with minimal tool wear.
2. Mechanical Strength
- Tensile Strength: ~340-470 MPa
- Yield Strength: ~145-310 MPa
- Good fatigue resistance for dynamic load applications.
3. Corrosion Resistance
- Excellent resistance to water, atmospheric corrosion, and many chemicals.
- Not suitable for highly acidic or ammonia-rich environments.
4. Thermal & Electrical Conductivity
- High thermal conductivity (~120 W/m·K), useful for heat exchangers.
- Excellent electrical conductivity (~28% IACS), ideal for electronic parts.
5. Wear Resistance & Lubricity
- Naturally low friction, making it suitable for bushings and bearings.
Environmental Suitability
C360 brass performs well in various conditions:
- Temperature Range: -40°C to 200°C (-40°F to 392°F) (avoid extreme thermal cycling).
- Humidity Resistance: Good corrosion resistance in moist environments.
- Chemical Exposure: Resistant to water, oils, and mild chemicals (avoid strong acids/alkalis).
Machining Tolerances & Surface Finish
C360 brass is one of the easiest materials to machine, allowing for tight tolerances and fine finishes:
- Standard Tolerances: ±0.025mm (±0.001″) (tighter tolerances achievable with precision setups).
- Surface Finish: Can achieve Ra 0.4µm (16 µin) or better with fine machining.
- Secondary Operations: Polishing, plating (nickel, chrome), and anti-tarnish coatings available.
Durability & Longevity
- High fatigue resistance for moving parts.
- Excellent wear properties in low-friction applications.
- Long-term corrosion resistance in typical industrial environments.
