LUXAL®Highly Smooth
Outline
We have succeeded in Roll to Roll production of highly smooth aluminium foil with surface roughness of 10 nm or less.
Not only does this foil retain the same high surface levels as other mirror metal plates, it also provides the high heat resistance, electrical conductivity, and flexion rate inherent in aluminium foil.
Proposed applications (also suitable for laminates and thin film coatings)
