General Specifications
Copper Round Bar Grades
From high-conductivity ETP to free-machining tellurium copper and high-strength beryllium copper — select the right alloy grade for your application.
Copper 110 – ETP Round Bar
Standard ETP copper round bar with 100% IACS conductivity. The most widely used grade for general electrical and industrial applications.
Copper 145 – Tellurium Round Bar
Free-machining tellurium copper round bar with 85-rated machinability. Ideal for high-volume screw machine operations requiring conductivity.
Copper 147 – Sulfur-Bearing Round Bar
Free-machining sulfur copper round bar. Excellent machinability with improved hot workability compared to tellurium grades.
Copper 172 – Beryllium Copper Round Bar
Ultra-high-strength beryllium copper round bar. Age-hardenable to 200+ ksi tensile strength with non-sparking properties for hazardous environments.
Copper 187 – Leaded Copper Round Bar
Leaded copper round bar for maximum machinability in high-volume screw machine operations. Good conductivity with superior chip-breaking characteristics.
Copper 110 — ETP
Electrolytic Tough Pitch (UNS C11000)
The world's most widely used copper alloy. Copper 110 delivers 101% IACS electrical conductivity with excellent formability, solderability, and corrosion resistance. It is the industry standard for busbars, electrical connectors, roofing, and virtually any application requiring high-purity copper.
