Why do you use silver ink rather than copper, aluminum, or titanium?
That is a great question, for this one we went to Jerry King, our Lab Supervisor, who knows the in's and out's of conductive printing.
Silver is used most because it is a very low resistance conductor, and it performs well environmentally.
Metals oxidize when exposed to oxygen and moisture (along with other oxidizing agents). This oxide is not very conductive and has a negative impact on the materials performance. One unique thing about silver is that when it does oxidize, it’s oxide layer is very conductive; this leads to a better performing material for the life of the product.
