NOTES:
1. Electrical resistivity and thermal conductivity are evaluated usually at 20°C and 85°C respectively.
2. Electrical resistivity is inverse to electrical conductivity.
3. Electrical conductivity is often expressed in % IACS which stands for International Annealed Copper Standard.
100% IACS is electrical conductivity of annealed copper which equals to 58.0 × 106 S⋅m-1.
4. Tensile strength in kgf/cm² may be converted to psi (pounds per square inch) by multiplying with 14.22.
