Copper’s versatility isn’t just about pure copper—in many industrial applications, specific copper alloys deliver tailored performance. Whether you need extra strength, superior corrosion resistance, or enhanced machinability, selecting the right alloy is crucial. In this blog, we explore five widely used copper alloys, their unique properties, and the applications that benefit most from each grade.
1. C10100 (Electrolytic Tough Pitch Copper)
Key Properties:
Electrical Conductivity: ≥ 100% IACS
Thermal Conductivity: 390 W/m·K
Machinability: Moderate
Ideal Uses:
Busbars and electrical conductors
Cable lugs and connectors
High‑current switchgear components
Why Choose C10100?
If maximum conductivity is your priority—such as in power distribution panels or grounding systems—C10100 ensures minimal power loss and excellent heat dissipation.
2. C11000 (Oxygen‑Free Electronic Copper)
Key Properties:
Conductivity: ≥ 101% IACS
Minimal Oxygen Content (< 0.02%)
Excellent Weldability
Ideal Uses:
Vacuum and cryogenic equipment
High‑reliability connectors in aerospace and medical devices
RF and microwave components
Why Choose C11000?
For critical electronic or vacuum applications, oxygen‑free copper prevents embrittlement and ensures long‑term reliability.
3. C83600 (Free‑Cutting Brass‑Bronze Blend)
Key Properties:
Lead Content: 2–3% for machinability
Tensile Strength: ~ 310 MPa
Machinability Rating: 80 (ASTM standard)
Ideal Uses:
Precision‑machined components like terminal blocks and fittings
Turned parts requiring tight tolerances
Rapid‑production CNC applications
Why Choose C83600?
Its exceptional machinability lets you achieve fine features and smooth threads, reducing cycle times and tooling wear.
4. C92700 (Tin Bronze)
Key Properties:
Tin Content: 5%
Wear Resistance: High
Corrosion Resistance: Excellent
Ideal Uses:
Pump impellers and valve stems
Marine hardware and seawater fittings
Bearing and bushing applications
Why Choose C92700?
In high‑wear or corrosive environments, tin bronze delivers durability while maintaining dimensional stability under load.
5. C95500 (Tellurium Copper)
Key Properties:
Tellurium Content: 0.5–1.0%
Machinability Rating: 85–90
Conductivity: ~ 70 % IACS
Ideal Uses:
Electrical switchgear components
Decorative architectural hardware
Heat exchanger tubes
Why Choose C95500?
Tellurium copper combines good conductivity with superior machinability, making it ideal for complex shapes and decorative finishes.
