What Aluminum Grade Should I Use?

What is the strongest Aluminium alloy?

7068 aluminium alloy7068 aluminium alloy is one of the strongest commercially available aluminium alloys, with a tensile strength comparable to that of some steels..

What does the 6061 mean in aluminum?

6061 (UNS designation A96061) is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements. Originally called “Alloy 61S”, it was developed in 1935. … It is one of the most common alloys of aluminum for general-purpose use.

What is 6063 aluminum used for?

6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames.

Is Aluminium as strong as steel?

Even with the possibility of corrosion, steel is harder than aluminum. Most spinnable tempers and alloys of an aluminum dent, ding or scratch more easily as compared to steel. Steel is strong and less likely to warp, deform or bend underweight, force or heat. … Steel is typically 2.5 times denser than aluminum.

What are the weaknesses of aluminum?

Aluminum alloys will warp at high temperatures and unlike steel, do not glow red before melting. Aluminum alloys also feature a lower fatigue limit than steel and will continually weaken with repeated stress. They are rarely used in fabrication applications that require high fatigue rates.

Which aluminum is stronger 6061 or 6063?

For applications that require higher strength, 6061 or 6082 are typically used. 6063 is primarily used for applications that are exposed because it suffers weather better than 6061, making it more corrosion resistant. Their slightly different characteristics make each one a better choice for different applications.

Which aluminum is hardest?

Aluminum 2024-T351 An aluminum hardness classification of 2024-T351 is one of the hardest aluminum alloys, widely used in the metal industry. This alloy has good formability but poor strength when it is heated; due to this drawback, it cannot be used for welding purposes.

Does bending aluminum weaken it?

If you bend anything harder than 5054 aluminum, you will need to anneal it by heating along the bend line. … When aluminum gets hot, first it is malleable, then it gets brittle, and then it melts. When you heat aluminum too close to the melting point and then try to bend it, the workpiece can crack or break.

Does heating aluminum weaken it?

Just like steel, aluminum alloys become weaker as the service temperature rises. But aluminum melts at only about 1,260 degrees, so it loses about half of its strength by the time it reaches 600 degrees. … Most codes do not give allowable stresses for aluminum alloys for service temperatures above 350 degrees.

What type of aluminum is best for bending?

Aluminium alloy 3003 excellent for bending The best series for forming – and thus for bending – are the alloy series 3xxx, 5xxx and in some cases 6xxx. Aluminium alloy 6063 is a good choice, for example, while 6082 is more difficult.

What is the best marine grade aluminum?

Grade 5052 is an excellent marine grade for when formability is required. If strength is more of a concern, grade 5083 is a good alternative. 6061-T6 is an all-around popular grade of aluminum that is also commonly used in marine applications. It has very good corrosion resistance and is precipitation hardened.

Is aluminum easy to bend?

Properties of Aluminum Unlike iron, aluminum is resistant to corrosion and oxidation. … Aluminum is very malleable, meaning it is easy to bend, so it is an unsuitable direct replacement for steel. At just 1,220 degrees Fahrenheit, aluminum has by far the lowest melting temperature of any metal used industrially.

Can you bend 6061 aluminum?

Ideally, part designers should know that when it comes to aluminum grades, 3003 and 5052 will bend, 6061 will not. This is generalizing, of course, as there are ways to form 6061. The aluminum series’ ability to bend tends to decrease as you move down the list of tempers, from annealed to T4 and T6.

Is Aluminium stronger than iron?

They also come up with difference in the chemical and physical properties. One of the first differences that one can come across between the two metals is that iron is heavier than Aluminium. Aluminium has only a specific weight of 2.7 g/cm3, which is much lower than iron.

What is the difference between 5052 and 6061 aluminum?

6061 aluminum does not have as high a fatigue strength as 5052 aluminum (96.5 MPa VS. … 6061 aluminum has a higher thermal conductivity than 5052 aluminum, making it the preferred choice for heat dissipation applications. For all the reasons 6061 aluminum fails as a forming alloy, it succeeds as a machining alloy.

What is the cheapest type of aluminum?

6061 is the most common of the aluminum alloys and is usually the cheapest.
