MEI rolls thin-gauge copper foil down to 0.04 mm for applications where conductivity, formability, and uniform thickness are critical. Produced on precision rolling mills with rigorous inline gauge control, our foil offers a smooth, clean surface free of slivers and edge burrs \u2014 essential for winding, shielding, and laminating operations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Thin-gauge rolling down to 0.04 mm is a specialist capability \u2014 our mills hold tolerance at foil gauges that many general rolling mills cannot, with full traceability
from cast bar to finished coil.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
