High-Precision Custom Machining, Cut-to-Size Components, and Raw Materials for Industrial Applications.
Pure Red Copper (Alloy C11000 / C10200)
Often referred to as pure copper, Red Copper is industry-standard for applications requiring maximum electrical and thermal conductivity. With a copper purity of ≥99.9%, it offers outstanding malleability and corrosion resistance.
Key Material Characteristics:
- Ultra-High Conductivity: Exceptional electrical and thermal transfer ratings.
- Superior Ductility: Excellent for deep drawing, stamping, and cold working.
- Corrosion Resistance: Forms a protective oxide layer that resists atmospheric and water corrosion.
- Excellent Joining Properties: Highly suited for soldering, brazing, and laser cutting processes.
Common US Applications:
Electrical busbars, switchgears, grounding hardware, heat exchangers, radiators, high-end architectural accents, and precision laser-cut electrical contacts.
High-Performance Brass Alloys
Brass alloys (Copper-Zinc systems) offer superior mechanical strength, excellent wear resistance, and outstanding machinability. Below is our US ASTM standard selection chart to help you choose the right grade for your CNC machining or fabrication project:
| Grade | Material Features & Properties | Primary Industrial Applications |
|---|---|---|
| C28000 | Muntz Metal. Classic forging leaded brass. Excellent hot-working capacity. | Heavy-duty valves, industrial pipe fittings, pump cylinders, and structural hardware. |
| C27200 | ~62% Copper content. Exceptional hot-working and forming performance. | Pins, rivets, fasteners, structural components, and cold-headed parts. |
| C26800 | Yellow Brass (~65% Copper). Optimal balance of strength, cost-efficiency, and workability. | Industrial fasteners, small hardware, electrical stampings, and hinges. |
| C26200 | High brass with superior ductility and excellent deep-drawing properties. | Complex cold-stamped parts, automotive components, and deep-drawn shells. |
| C26000 | "73 Brass" (~30% Zinc). Highest ductility in the alpha-brass family. Outstanding cold-working capability. | Radiator cores, heat exchanger shells, cold-rolled sheets, and cartridge casings. |
| C24000 | Low Brass (~80% Copper). High strength combined with excellent formability and acoustic properties. | Industrial bellows, flexible metal hoses, mesh screens, and musical instruments. |
| C22000 | Commercial Bronze (~90% Copper). Rich golden color, excellent corrosion resistance, and high ductility. | Architectural trims, high-end jewelry blanks, ammunition primers, and marine hardware. |
