xRapidKeen Small-to-Medium Brass Rods 6mm (0.236") - 15mm (0.591") Diameter
Discover the industry-standard performance of RapidKeen Small-to-Medium Brass Rods. Spanning from 6mm to 15mm in diameter, this particular size range represents the ultimate "sweet spot" for standard commercial hardware, CNC turning centers, and rapid-cycle automated manufacturing. RapidKeen provides consistent structural homogeneity, allowing multi-axis lathes to operate at peak spindle speeds without risking premature tool wear or material deflection.
Alloy Architecture: C27200 vs. C28000
The 6mm - 15mm size range heavily utilizes specific industrial brass alloys to perfectly match your engineering and secondary processing requirements:
- C27200 (Yellow Brass / 63-37 Brass): Consisting of a 63% Copper and 37% Zinc matrix, C27200 stands out for its unmatched cold workability. If your manufacturing process requires a combination of high-speed CNC turning along with secondary cold operations—such as heavy knurling, thread rolling, stamping, expanding, or cold flaring—C27200 is the optimal material. It resists cracking under stress and provides superb resistance to atmospheric corrosion.
- C28000 (Muntz Metal / 60-40 Brass): This 60% Copper and 40% Zinc duplex alloy is engineered for applications demanding pure mechanical strength and rigidity. C28000 is harder and tougher than C27200, making it highly reliable for threaded fasteners, high-stress pins, and components exposed to harsher fluids or industrial environments. Its excellent hot-forming capability allows it to be easily forged or headed hot when complex geometries are required.
Note: We also provide standard free-cutting alloys like C36000 for high-volume, straight-forward machining projects where maximum chip-breaking efficiency is the singular priority.
Massive Range of Industrial Applications
The 6mm to 15mm diameter range is the most heavily consumed stock size worldwide, used across countless vital sectors, including:
- Standard Hardware & Fasteners: High-grade industrial machine screws, hex nuts, custom shoulder bolts, dowel pins, rivets, and heavy-duty threaded studs.
- Plastic Injection Molding Inserts: Precision knurled threaded inserts designed for ultrasonic or thermal post-molding installation into engineered plastics.
- Fluid & Pneumatic Fittings: Quick-connect hose barbs, compression sleeves, air line ferrules, and pipe adapters.
- Consumer Electronics: Core metal components for electronic vaping devices, custom audio jack housings, and grounding lugs.
