2. Core Features of Copper Strip Product
2.1 Physical and Chemical Residences
Copper strip materialis commemorated for its resistant physical properties and chemical inertness. Trick characteristics consist of:
High Electrical Conductivity: Copper’s conductivity (58 MS/m) places second just to silver, ensuring minimal energy loss in electrical systems.
Thermal Conductivity: With a thermal conductivity of 401 W/m · K, copper effectively dissipates warm, important for thermal management in electronic devices.
Mechanical Toughness: Despite its malleability, copper strips show exceptional tensile toughness (up to 220 MPa), allowing resilience in architectural applications.
Rust Resistance: A self-forming passive oxide layer (Cu ₂ O) safeguards against ecological destruction, also in humid or saline conditions.
