Low-volume manufacturing of industrial components demands materials that offer excellent machinability, consistent quality, and cost-efficiency. Brass C360, also known as free-machining brass, is particularly suited to precision CNC machining due to its exceptional machinability (rated 100%) and ability to achieve tight tolerances (±0.005 mm). This makes it ideal for producing fittings, connectors, valves, and intricate mechanical parts required in industrial equipment, automation systems, and consumer products.
Utilizing professional CNC machining services, manufacturers optimize small-batch production, delivering high precision, consistency, and cost-effectiveness in brass industrial components.
Material | Tensile Strength (MPa) | Machinability | Corrosion Resistance | Typical Applications | Advantage |
---|---|---|---|---|---|
360-400 | Excellent (100%) | Good | Valves, connectors, fittings | Exceptional machinability, precise tolerances | |
380-420 | Very Good (90%) | Good | Complex fittings, hardware | Good machinability, slightly higher strength | |
276-310 | Very Good (85%) | Excellent | Lightweight housings, structural parts | Lightweight, superior corrosion resistance | |
550-650 | Good (78%) | Excellent | Precision shafts, valves | High strength, excellent corrosion resistance |
Selecting the optimal material for low-volume CNC machined industrial parts involves balancing machinability, precision, mechanical properties, and corrosion resistance:
Brass C360 is ideal for precision fittings, connectors, and valves due to its outstanding machinability (100%), enabling rapid and precise machining even in intricate geometries.
Brass C377, offering slightly higher tensile strength (up to 420 MPa), is suitable for applications requiring slightly more strength while maintaining excellent machinability.
Aluminum 6061-T6 suits components where weight savings and superior corrosion resistance are essential, ideal for precision housings and lightweight structures.
Stainless Steel SUS303 is best for applications demanding higher mechanical strength and exceptional corrosion resistance, such as precision shafts and valves, albeit with reduced machinability compared to brass.
CNC Machining Technology | Dimensional Accuracy (mm) | Surface Roughness (Ra μm) | Typical Applications | Key Advantages |
---|---|---|---|---|

±0.01-0.03 | 1.6-3.2 | Threaded fittings, precise holes | Quick turnaround, accurate processing | |
±0.002-0.005 | 0.05-0.2 | Sealing surfaces, precision interfaces | Exceptional precision, superior finishes |
Selecting the correct CNC machining process depends on the complexity, accuracy requirements, surface quality, and specific functional requirements:
CNC Milling effectively handles complex brass components requiring intricate geometries, precise shaping, and tolerances (±0.005-0.01 mm), ideal for valve housings and custom fittings.
CNC Turning is highly efficient for producing cylindrical components such as connectors and precision fittings, delivering tight tolerances and consistent dimensional accuracy.
CNC Drilling is suitable for rapidly creating threaded fittings and precise mounting holes with moderate dimensional tolerances (±0.01-0.03 mm), essential for quick-turnaround small-batch production.
CNC Grinding delivers ultra-high precision (±0.002-0.005 mm) and exceptional surface finishes (Ra ≤0.2 μm), particularly beneficial for sealing surfaces and precision interfaces in industrial components.
