a) U.S. patent #5527628 issued on the 18-June-1996 to SMIC (Senju Metal
Industry Co.), will expire internationally on the 24-Feb-2015;
b) U.S. patent #4929423 issued on the 29-May-1990 to Cookson Group,
expired internationally on the 31-Mar-2009;
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 × 10
6 S⋅m
-1.
4. Tensile strength in kgf/cm² may be converted to psi (pounds per
square inch) by multiplying with 14.22.
