Re-rolled metal foil down to 1.5 microns (0.000060

Metal Foil

Hamilton Precision Metals is the world leader of precision-rolled foil and ultra-light gauge strip in any alloy. This includes stainless steel foil, titanium foil, nickel foil, copper based foil, cobalt based foil, Constantan® foil, Evanohm® foil, and many other alloys. Metal foil is generally defined as strip 0.004” (0.1016 mm) and below. Cold rolling strip to these extremely thin gauges demands extensive rolling expertise to manufacture with precision and consistency.
Foil in Any Alloy
We offer the broadest portfolio of almost every high performance alloy made today. Additional alloys are available upon request, contact us today!
Tightest Tolerances and Thinnest Gauges in the Industry
We custom roll metal foil in nearly any alloy and specialty metal to the tightest tolerances and thinnest gauges in the industry – down to 1.5 microns (.000060”) in thickness. That’s about 1.5% the thickness of a human hair!

Tailored Surface Finishes
From ultra-smooth to roughened matte, Hamilton Precision Metals has the expertise to control your desired surface finish.
