Specialty Foils
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).
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 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:
