Aluminium alloy 3003 is a medium strength alloy with very good resistance to atmospheric corrosion and very good weldability as well as good cold formability. It has better mechanical properties, especially at elevated temperatures than the 1000 series alloys.
Applications - Alloy 3003 is typically used for:
Building industry: roofing and sidings, acoustic ceilings, corrugated sheets
Chemical and food industries: storage tanks, pipes, metal work
Equipment for heating and cooling: heat exchangers, air condition evaporators, motor vehicle radiators, freezer linings
Home appliances: cooking utensils, bakery moulds
Office equipment
Tube & Pipe
Packaging: containers, closures. Cladding alloy.
