xRapidKeen Premium Micro & Fine Brass Rods (1mm (0.04") - 5mm (0.197") Diameter)
Welcome to RapidKeen, your premier destination for high-precision metals. Our ultra-fine and micro brass rods, ranging from 1mm to 5mm in diameter, are engineered specifically for high-tech, medical, electronic, and micro-machining industries where absolute dimensional stability and tight tolerances are mandatory. We maintain strict manufacturing controls to ensure a premium surface finish and straightness that exceeds industry standards.
Advanced Material Grade Specifications
At RapidKeen, we specialize in high-purity brass alloys tailored for complex engineering demands. This product line focuses heavily on two premium grades:
- C27200 (Yellow Brass / 63-37 Brass): This exceptional alpha brass offers a superior combination of cold-working capacity, ductility, and strength. With a composition of 63% Copper and 37% Zinc, C27200 is the ultimate choice for micro-manufacturing processes that involve intricate cold-heading, spinning, severe bending, or wire forming before final machining. It provides outstanding corrosion resistance and a beautiful, uniform bright gold finish.
- C28000 (Muntz Metal / 60-40 Brass): A robust duplex alpha-beta brass consisting of 60% Copper and 40% Zinc. C28000 delivers significantly higher structural strength, rigidity, and hardness compared to lower zinc alloys. It exhibits excellent hot-working properties and is heavily utilized for micro-components subjected to higher mechanical loads or exposed to marine, coastal, and mild industrial corrosive environments.
Note: Other specialty commercial grades such as C36000 free-cutting brass are available upon brief inquiry for high-speed automatic lathe operations.
Comprehensive Application Breakdown
Our 1mm to 5mm ultra-fine brass rods are incredibly versatile. Thanks to their consistent alloy structure, they are highly sought after for the following applications:
- Electronics & Communication: RF coaxial connectors, micro-connector pins, pogo pins, electrical test probes, and shielding components.
- Precision Instruments: High-precision clock/watch internal gears, miniature shafts, balance wheels, and scientific laboratory measuring devices.
- Additive Manufacturing: Premium raw stock for machining high-precision 3D printer extruder nozzle cores and throat tubes.
- Medical Equipment: Non-magnetic surgical instrument components, diagnostic sensor housings, and micro-valves.
