Copper Grades Explained: ETP, EC, OFC and DHP Copper
Copper is widely used in electrical systems, industrial manufacturing, plumbing, refrigeration, and electronic applications. However, different copper grades offer different properties depending on their oxygen content, phosphorus content, purity, and electrical conductivity. Understanding these differences helps manufacturers and engineers select the right copper for their specific requirements. Read More Understanding Different Copper Grades ETP Copper Electrolytic Tough Pitch (ETP) copper is one of the most commonly used commercial copper grades. It typically contains a minimum of 99.90% copper and provides electrical conductivity of at least 100% IACS in the annealed condition. ETP copper is widely used in copper busbars, electrical strips, wires, cables, transformer windings, switchgear components, and electrical terminals. Its high conductivity makes it suitable for applications that require efficient electrical transmission. However, ETP copper can be susceptible to hydrog...
