Aluminum foil is a kind of hot stamping material which is directly calendered into foil by aluminum coils. Its hot stamping effect is similar to that of pure silver foil stamping, so it is also called fake silver foil. Since aluminum has a soft texture, good ductility, silvery white luster, if the calendered sheet is smashed on an offset paper with a material such as sodium silicate, an aluminum foil can be formed, and printing can be performed on it. However, the aluminum foil itself is easily oxidized and the color is darkened, and friction or touch can make it discolored, so it is not suitable for hot stamping of a book cover that has to be preserved for a long time.

Alloy 52,ASTM F30,UNS K95050,(Fe-50Ni),Chinese 4J50 Alloy 52 is a 52% nickel-iron alloy developed for glass-to-metal seals for some of the soft glasses and some ceramics. Produced with good machining properties, it’s manufactured in a controlled environment under controlled conditions.
Shock-Proof & Wear Resistance axle-centre alloy (YB/T5243-1993) Axle-centre alloy Is a kind of elasticity of nickel-based alloy, with high strength, hardness and elasticity, corrosion resistance and non-magnetic characteristics.
Permalloy80 is a highly magnetic nickel-molybdenum-iron alloy, with roughly 80% nickel and 15% iron and 5% molybdenum content. It's useful as a magnetic core material in electrical and electronic equipment. Permalloy 80 provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction which is critical for industrial applications.
