Aluminum is the most widely used non-ferrous metal worldwide, with physical properties suited for a range of different applications. But with so many grades from which to choose, how do you ensure you pick the right material for the job?
Let’s start at the top—with some common properties shared across all grades of aluminum:
Feature
Characteristic
Light Weight
1/3 weight of steel
Corrosion resistance
Low maintenance, longevity, and improved performance
High Strength-to-Weight Ratio
Very strong in proportion to its total weight
High Electrical Conductivity
Copper is rated higher but can be three times as heavy
As one of most used grades of aluminum in any shape, 6061 contains alloying elements like magnesium (1.0%) and silicon (0.6%). This makes is highly resistant to corrosion, stress, and cracking. This grade also features good formability and weldability.
Alloyed with 1-2% manganese, aluminum sheet 3003 has a tensile strength range of 17 to 30 KSI. This grade is considered to have excellent workability, weldability, and corrosion resistance, which makes it ideal for fuel tanks and sheet metal work, among other applications.
This grade of aluminum is alloyed with 2.5% magnesium, with a tensile strength range of 31 to 44 KSI. Expect a highly corrosion-resistant grade with good workability, weldability and strength.
Aluminum 5052 is ideal for aircraft fuel tanks, storm shutters, refrigerator liners, utensils, electronic mounting plates and panels.
