Aluminium foil (or aluminum foil in American English; often informally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
Aluminum foil is one of the hottest aluminum material products in the national market. It takes aluminum alloy as material. 3003 aluminum foil is the common aluminum alloy material in the aluminum foil series. And it’s also a common product of Al-Mn series alloys. Due to the aluminum alloy contents Mn element, the foil has excellent rust resistance, weld-ability and corrosion resistance. So, it’s the first choice for electrolytic capacitor, lunch box container, and aluminum honeycomb core material.
3003 aluminum alloy is an Al-Mn alloy. The strength of the aluminum foil is slightly higher than that of commercial pure aluminum. We can’t strengthen it’s properties by heat treatment. And only cold working methods can improve its mechanical properties.
Such alloys have high plasticity in the annealed state. In addition, during cold work hardening, it has low plasticity, good corrosion resistance and good weld-ability.3003 aluminum alloy is mainly used for parts with high requirements, plasticity and good weld-ability, such as fuel tanks, gasoline or lubricating oil conduits, various liquid containers and other small load parts made by deep drawing, etc.
Advantages of 3003 aluminum foil:
1. The elongation rate of 3003 alloy aluminum foil is controllable and can be set according to customer requirements.
2. High tensile strength.
3. After welding with the tabs, it is firm and not easy to fall off.
4. The quality of 3003 aluminum foil is stable, long-term supply, no serious bubble sand phenomenon.
