Pure C11000 Copper Earth Rod
Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of pure c11000 copper earth rod in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount pure c11000 copper earth rod for sale here from our factory. Customized orders are welcome.
C11000 Copper Alloy, also known as Electrolytic Copper, is a high purity copper material whose main component is copper (Cu) at a content of over 99.95%. This copper alloy is widely used in various fields such as electronics, electrical, communications, aerospace, etc. for its excellent electrical and thermal conductivity.
Unlike standard copper-bonded steel rods, our rods are manufactured from 100% Solid Electrolytic Tough Pitch (ETP) Copper (UNS C11000). With an electrical conductivity of 100% IACS, they provide the lowest possible resistance path to ground.
These rods are specifically engineered for highly corrosive soil environments (such as coastal areas or chemical plants) where steel-cored rods would fail. We offer exceptional service life, often exceeding 50 years.

Key Features
100% Solid Copper: No steel core. Eliminates the risk of galvanic corrosion between the copper layer and steel core.
Ultimate Conductivity: IACS ≥ 100%. Ensures rapid dissipation of fault currents and lightning strikes.
Extreme Durability: Excellent corrosion resistance in acidic or saline soils. Will not rust or degrade over time.
High Strength: Hard-drawn temper ensures the rod is rigid enough to be driven into the ground without bending.
Extendable Design: Available with threaded ends and brass couplers for deep driving requirements.
