General Specifications
Copper Busbar Grades
We stock multiple copper alloy grades for busbar applications. Select the right alloy for your conductivity, temperature, and fabrication requirements.
Copper 110 – ETP (Electrolytic Tough Pitch)
The most widely used copper alloy in the world. C110 ETP offers 101% IACS conductivity with excellent formability, solderability, and corrosion resistance — the standard choice for electrical busbar and power distribution applications.
Conductivity
101% IACS
Cu Content
99.90% min
Key Feature
Industry Standard
Copper 101 – High Conductivity (ETP)
The industry benchmark for electrical conductivity. Copper 101 offers 100% IACS conductivity with excellent ductility, making it the go-to choice for general-purpose busbar applications in power distribution and grounding systems.
Copper 102 – Oxygen-Free (OF)
Premium oxygen-free copper with superior ductility and freedom from hydrogen embrittlement. Ideal for applications requiring brazing, welding, or use in reducing atmospheres where ETP copper would be compromised.
Copper 116 – Silver-Bearing Tough Pitch
ETP copper enhanced with silver (25 oz/ton minimum) for improved creep resistance at elevated temperatures. Maintains conductivity while providing superior strength retention up to 200°C — critical for high-temperature busbar installations.
Copper 107 – Oxygen-Free Silver-Bearing
Combines the benefits of oxygen-free purity with silver additions for enhanced softening resistance. Provides excellent performance in high-temperature, high-reliability busbar applications where both weldability and thermal stability are required.
Applications for Copper Busbars
Copper busbars are the backbone of electrical power distribution across virtually every industry.
Power Distribution
Primary conductors in switchgear, panelboards, and motor control centers. Busbars carry high currents with minimal voltage drop across the distribution system.
View Industry →Industrial Manufacturing
Electroplating busbars, welding jigs, and high-current fixtures used in automotive, aerospace, and heavy industrial manufacturing environments.
View Industry →Data Centers
Critical power infrastructure for server racks and UPS systems. Copper busbars ensure reliable, low-resistance connections for 24/7 uptime requirements.
View Industry →EV & Automotive
Battery pack interconnects, charging infrastructure, and high-voltage distribution in electric vehicles demand the conductivity and reliability of copper busbars.
View Industry →Grounding & Lightning Protection
Earth busbars and ground bus systems for commercial buildings, substations, and telecommunications facilities. Critical safety infrastructure.
Renewable Energy
Solar inverters, wind turbine generators, and energy storage systems rely on copper busbars for efficient power conversion and transmission.
