Thin Gauge Aluminum Foil

Aluminum is rolled by Alcan Singen of Singen, Germany, an Alcan company, to very thin gauges ranging from .00016" (4.0 microns) to .00040" (10 microns). These foils, rolled from alloy AA1200 (99.12%) aluminum, are supplied fully annealed and dry. The minimum widths of our thin gauge foils vary greatly based on the thickness of the foil, though all the foils are available from 1/2" (12.7 mm) to 25 inch (638 mm).

Narrow Width Aluminum Foil

Thin foils are rolled and specially slit by APK, in widths down to 2.0 mm. All the foils are alloy AA1200 (99.12%) aluminum. The minimum thickness varies based on the desired width. All foils are slit to order in Switzerland.

Tin, Lead and Tin/Lead Alloy Foils

Tin foils are used for capacitor applications, electro-medical devices, electrical resistance for heating elements and a host of other electronic and medical applications. Lead foils are commonly supplied for a variety of specialty applications including: x-ray foils (both plain and laminated), x-ray intensifying foils and x-ray grid foils. To meet the growing need for lead or antimony free products, our mill has developed both lead and antimony free alloys to meet the needs of the medical and electronics markets. Our standard alloys include:
