GNEE Aluminum is an aluminum manufacturer and distributor dedicated to offering high-quality aluminum products and exceptional customer service. One of the alloys we manufacture is aluminum coil 3003.
3003 is the most popular of all aluminum alloys. It is essentially economically pure aluminum with the addition of manganese, which boosts strength by approximately 20% above the 1100 grade. As a result, it combines all of the advantages of 1100 with increased strength. It has exceptional corrosion resistance. It has great workability and can be deep drawn, spun, welded, or brazed. It is not heat treatable. Applications include cooking utensils, decorative trim, awnings, siding, storage tanks, and chemical apparatus.

3003 Aluminum Coil FAQ's
Can 3003 Aluminum Coil Be Anodized?
Aluminum coil 3003 can be anodized. It contains higher amounts of manganese which helps to protect the metal after anodization. However, the manganese content typically turns the resulting metal into an unattractive brown.
Is 3003 Aluminum Used In Automotive Manufacturing?
Yes, 3003 is one of the primary aluminum alloys used in the automotive industry. It has many uses in automobiles, including tubing for use in a vehicle's cooling system, fuel system and brake system. Aluminum 3003 is also commonly used to form the chassis of automobiles.
