SELECTING THE CORRECT GRADE OF ALUMINUM By Metal Supermarkets
Aluminum is a common metal used for both industrial and non-
We have compiled a short breakdown of each of the grades’ properties in order to provide you with a brief understanding of their many uses.
Alloy 1100: This grade is commercially pure aluminum. It is soft and ductile and has excellent workability, making it ideal for applications with difficult forming. It can be welded using any method, but it is non heat-
Alloy 2011: High mechanical strength and excellent machining capabilities are the highlights of this grade. It is often called – Free Machining Alloy (FMA), an excellent choice for projects done on automatic lathes. The high-
Alloy 2014: A copper based alloy with very high strength and excellent machining capabilities. This alloy is commonly used in many aerospace structural applications due to its resistance.
Alloy 2024: One of the most commonly used high strength aluminum alloys. With its combination of high strength and excellent fatigue resistance, it is commonly used where a good strength-
Alloy 3003: The most widely used of all aluminum alloys. A commercially pure aluminum with added manganese to increase its strength (20% stronger than the 1100 grade). It has excellent corrosion resistance, and workability. This grade can be deep drawn or spun, welded or brazed.
Alloy 5052: This is the highest strength alloy of the more non heat-
Alloy 6061: The most versatile of the heat-
Alloy 6063: Commonly known as an architectural alloy. It has reasonably high tensile properties, excellent finishing characteristics and a high degree of resistance to corrosion. Most often found in various interior and exterior architectural applications and trim. It is very well suited for anodizing applications. The Tube and Angle shapes in this grade typically have square corners.
Alloy 7075: This is one of the highest strength aluminum alloys available. It has an excellent strength-
For more specific applications, we have put together a table that will easily let you decide on what Aluminum grade to use for your project.
