Aluminum 5052 VS 6061, differences between alloy 5052 H32 & 6061 T6

Introduction:

In the construction industry, there are many kinds of plates have different alloy number. For example, the aluminum sheet has alloy number 5052 and alloy number 6061. These two specifications of the aluminum plate in the chemical composition and production process are similar, but some are not the same. Today I will talk to you about the difference between 5052 and 6061 related content and information. I hope it can bring help to you. If you are interested in this, you can follow me to learn more.

 

5052 aluminum plate and 6061 aluminum plate is very much in line with the modern production process standards, so many consumers on its development trend are also very good. After all, 6061 aluminum alloy plate and 5052 aluminum alloy plate characteristics in the vast degree are different, and in the antioxidant capacity has also done a lot of research in a certain degree can also stop the erosion of external substances. So the aluminum plate also assumed the role of anti-slip, suitable for use in a variety of fields.

Aluminum 5052 alloy

Aluminum alloy 5052 belongs to the 5000 series aluminum sheet. Its main element is magnesium. The magnesium content is between 3-5%, which can also be called an aluminum-magnesium alloy. The main characteristics are low density, high tensile strength, and high elongation. The weight of aluminum-magnesium alloy in the same area is lower than other series. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in the conventional industry. The processing process is continuous casting and rolling. It belongs to the hot-rolled aluminum sheet series, so it can do oxidation deep processing. In China, 5000 series aluminum sheet is one of the more mature aluminum sheet series.

Aluminum 6061 alloy

The main alloy elements in 6061 aluminum alloy are magnesium and silicon. The alloy 6061 has medium strength, good corrosion resistance, weldability, and good oxidation effect. The standards are ASTM B209 or GB/T3880-2006. Alcoa 6061 has excellent processing performance, good corrosion resistance, high toughness and no deformation after processing, easy color film, excellent oxidation effect, and other excellent features.

Comparing 6061 & 5052 Aluminum alloys:

Many customers want to know the difference between 6061 t6 and aluminum 5052. 6061 aluminum alloy can be produced with T5, T6, T651, T6511 temper. 5052 aluminum alloy is generally H112, H34, H32, O state. Alloy 6061 is generally used in places with higher strength, 5052 is generally used in occasions where the strength is not so high, 5052 is more pursuing the function of rust resistance, rather than strength resistance. Even though both 5052 aluminum plate and 6061 aluminum plate are our frequently used aluminum plate, they still have a very obvious difference.

Firstly, Chemical Composition: 

The first difference is the alloying elements. 5052 aluminum plate’s main alloying element is magnesium, with good forming and processing properties, corrosion resistance, weldability, medium strength. 6061 alloy aluminum plate of the elements in addition to magnesium also contains silicon. It has medium strength, good corrosion resistance, weldability, and good oxidation effect. 6061 aluminum plate has excellent processing performance, good corrosion resistance, high toughness, and no deformation after processing, easy color film, excellent oxidation effect, and other excellent features. The chemical composition of the two aluminum grades is as follows.

Second, Mechanical Properties.

6061 t6 aluminum properties VS 5052 aluminum properties. The mainly mechanical properties of aluminum plate are tensile strength and yield stress. 5052 aluminum plate is Al-Mg system rust-proof aluminum. 5052 has high strength, especially with high fatigue strength; similar to alloy 3A21, high plasticity, and corrosion resistance; heat treatment can not be strengthened, good weldability with contact welding and hydrogen atomic welding, argon arc welding with the tendency of crystalline cracking; an alloy in the cold hardening and semi-cold hardening state machinability is good, annealed state machinability The strength of ASTM B209 alloy 6061 aluminum plate is relatively high. Generally speaking, the hardness of state T6 and T651 is over 95HB, while the 5052H32 aluminum plate hardness is only about 60HB; the mechanical properties of the two aluminum grades are as follows.

Third, The Application:   

Due to the processing state and the difference of alloying elements, let the two kinds of the aluminum plate from the performance to the use also occurred the difference. 5052 aluminum plate application range is more extensive, poor machinability, polishable, used in the manufacture of aircraft fuel tanks, fuel pipes, and transportation vehicles, ship’s sheet metal parts, instrumentation, street light bracket, and rivets, hardware products, electrical shells, etc. 6061 aluminum plate has good corrosion resistance, weldability, and Good oxidation effect. Widely used in a variety of industrial structural parts requiring a certain strength and high corrosion resistance, manufacturing trucks, towers, ships, trams, railway vehicles, furniture, mold, etc. with aluminum tubes, aluminum bars, aluminum extrusion profiles, 6061 extruded aluminum.

 

Summary

Although the price of the 5052 aluminum plate and the price of the 6061 aluminum plate is relatively transparent, the manufacturer will add protective materials and corresponding alloy materials to the object in the process, so that the aluminum plate on the original basis, improve the performance of 5052 aluminum plate and 6061 aluminum plate.

 

Therefore, it has been recognized by many manufacturers. In addition, when we buy this product, we can also choose the right hardness and characteristics according to our needs to avoid the waste of materials.
