Copper resistivity: 1, copper resistivity ρ only copper conductors and materials, but also on the temperature of copper conductors and related. Little change in the temperature range, almost all of the metal resistivity changes linearly with temperature, i.e., ρ = ρo (1 + at). Where t is the Celsius temperature, ρo is O ℃ when the resistivity, a is a temperature coefficient of resistivity. 2, due to the resistivity of copper varies with temperature change, so the resistance for copper, which must explain their physical state. Copper resistivity: resistivity of copper (20 ℃ pm) of 0.017Ω · mm2 / m; we are under way for the thermal conductivity of copper is: 386.4w / (mk). Copper resistivity: As already introduced specific resistivity of copper, but copper, there are many brands and different grades of copper resistivity is a little bit different, we have to understand, are you, in Table 1 below, ordinary copper resistivity: Grade T1 T2 T3 C11000 C12500 resistivity / μΩ · m 0.0168 0.0171 0.0171 0.0170① 0.0176 Note ①: 100% IACS material -100 ~ 200 ℃ when the resistance temperature coefficient 0.00393 / K, 101% IACS material from -100 to 200 ℃ when the temperature coefficient of resistance of 0.00397 / K. H14 Status: 1.78μΩ · m. 97% IACS material 0 ~ 100 ℃ when the resistance temperature coefficient of 0.00381 / K. 2, oxygen-free copper resistivity: oxygen-free copper resistivity of 0.0171μΩ · m.

Copper resistivity is represented by ρ. 2, the resistance is a reflection of objects on the current impediment. Copper's resistance is no "one meter long copper conductor cross-section of 1 mm2, at 20 ℃," "This premise copper's resistance represented by R 3, the relationship between copper resistivity and resistance:.. R = ρl / s, where R is the resistance of copper; ρ is the resistivity of copper; l is the length of copper delivery time: 1-2 days normally, whether special circumstances may call including invoices: available 17% VAT, but need tax price sales material reports: Material test reports are available to ensure the quality of the product you have purchased shipping method: field Kuandaofahuo, local large courier delivery (long-term delivery available) .
