C11000 (ETP) Electrolytic Tough Pitch Copper
CDA 110, CA11000, ASTM B187, ASTM B152, SAE J461, J463, ASM F68

Mechanical values above are typical for 1" solid diameter Hard (35%) Temper

*Hardness conversions are approximate

**Test values are nominal approximations and depend on specimen size and orientation

The values listed above represent reasonable approximations suitable for general engineering use. Due to commercial variations in composition and to manufacturing limitations, they should not be used for specification purposes. See applicable ASTM specification references.

​

C11000 ELECTROLYTIC TOUGH PITCH (ETP) COPPER is known for its high electrical and thermal conductivity, good corrosion resistance and solderability. C11000 copper is used for welding fixtures, anodes, bus bar in electrical power installations, ground straps, commutators and current-carrying hardware. Its inherent fabrication qualities readily permit it to be bent, soldered, drilled, peened, riveted and formed to fit almost any design specification. This copper has excellent hot workability. C11000 ETP Copper conforms to ASTM B187 for bar and ASTM B152 for plate.

​

Copper is crucial for data centers, used extensively in power distribution, cabling, cooling, and switchgear due to its excellent electrical/thermal conductivity, reliability, and recyclability, with the massive power demands of AI fueling unprecedented growth in its use, creating supply chain challenges. While fiber optics handle long-haul data, copper's role in short-distance connections and critical infrastructure remains vital, even with evolving technology like Active Electrical Cables (AECs) to overcome distance limitations.

What's Driving
Metal Prices

Factors creating the on-going surge in copper prices and base metal prices.

The U.S. imposed a 50% Section 232 tariff on the copper content of semi-finished and derivative copper products, effective August 1, 2025. These tariffs aim to bolster domestic production but create complexities for businesses in pricing, sourcing, and compliance, affecting global copper markets. 

In addition copper costs are soaring due to massive demand from the energy transition (EVs, renewables, grid) and AI data centers colliding with slow mine supply growth, production disruptions (labor, technical issues), aging mines, and government policies like tariffs, creating a structural supply deficit. 

Tin prices jumped to a record level due to a severe, ongoing global supply squeeze from mine disruptions (DRC, Myanmar, Indonesia) and increasing demand driven by its critical role in electronics (solder), green energy tech, and packaging, creating a significant market deficit and attracting speculative investment. Supply chain issues, including export permit delays and political instability in key producing regions, combined with growing recognition of tin's necessity for the energy transition, fueled a rally to multi-year highs in late 2025 and early 2026. 

Nickel prices are rising due to anticipated supply cuts from major producer Indonesia, tighter quotas, increased demand from stainless steel and EV battery sectors (despite some LFP shifts), speculative buying, and broader market strength in metals, with investors reacting to policy signals and potential disruptions.
