· Product Overview
This comprehensive collection of precision-engineered brass components represents a full range of custom CNC-machined parts designed for diverse industrial, electrical, and mechanical applications. Crafted from high-grade free-cutting brass alloys, these parts showcase versatile geometries including threaded fasteners, bushings, guide pins, nozzles, knurled rings, and custom structural brackets. Brass’s inherent self-lubrication, excellent electrical/thermal conductivity, and natural corrosion resistance make these components ideal for high-wear, conductive, or fluid-handling systems, delivering reliable performance across demanding environments.
· Core Specifications
| Specification | Details |
|---|---|
| Base Material | C36000 Free-Cutting Brass (standard); C46400 Naval Brass / C93200 Bearing Bronze (customizable for enhanced corrosion/wear resistance) |
| Surface Finish | Precision-machined to Ra ≤ 1.6μm; optional finishes include knurling, polishing, passivation, tin plating, or nickel plating |
| Tolerance Standards | ±0.01mm for critical dimensions (up to ±0.005mm for high-precision parts), conforming to ISO 2768-m and ISO 965 thread standards |
| Core Machining Processes | CNC turning, milling, drilling, tapping, knurling, broaching, and precision grinding |
| Key Feature Range | Internal/external threading, knurled grips, precision guide pins, stepped profiles, custom mounting holes, and specialized fluid/electrical interface geometries |
