WebThe impact property is one of the most significant mechanical properties for metallic materials. In the current work, a soft–hard copper–brass block with a high yield strength of ~320 MPa and good uniform elongation of ~20% was prepared, and the effect of the testing temperature on its impact property was explored. The results … WebThe electrical conductivity of pure copper is sensitive to temperature, and less sensitive to the amount of cold work and the grain size. The linear temperature coefficient for electrical resistivity in copper is dρ/dT = 6.7×10 −11 Ω m K −1. 30 Severe cold work can reduce the electrical conductivity of copper by only 2–3% IACS.
