Copper Fibre Electrical Conductivity Applications
topic
Copper fibres with electrical resistivity of 0.017 microohm metres provide 40 times lower resistivity than stainless steel, enabling woven and knitted copper fibre fabrics to achieve EMI shielding effectiveness above 60 decibels at gigahertz frequencies; fine copper wire of 25 to 100 micrometre diameter is wrapped onto textile core yarns or woven as weft into conductive fabric circuits for flexible electronics applications.
Role
Provides the highest conductivity metal fibre option for applications requiring maximum EMI shielding effectiveness, minimum resistance circuit interconnects, or efficient current-carrying capacity in heated textiles, with the trade-off of lower corrosion resistance than stainless steel requiring protective coating or design measures to maintain conductivity in sweat and humid environments.
