What Is 5052 and 5754 Aluminum Strength

 In the vast world of aluminum alloys, 5052 and 5754 aluminum alloys have become effective materials in many fields due to their unique properties.

Strength characteristics of 5052 and 5754 aluminum alloys.

5052 aluminium alloy

5052 aluminum alloy belongs to Al-Mg alloy. Its tensile strength fluctuates between 170-305MPa, showing a medium strength level. In some occasions where there are certain requirements for 5052 aluminum strength and other properties need to be taken into account, 5052 aluminum alloy can meet the needs well.

Its conditional yield strength is ≥90MPa, and its elastic modulus is in the range of 69.3 - 70.7Gpa. These data indicate that it can maintain good structural stability when subjected to stress and is not prone to excessive deformation.

5754 aluminum alloy

5754 aluminum alloy also belongs to the Al-Mg alloy family. Its tensile strength is generally in the range of 165-265MPa, and it also shows medium strength characteristics. However, compared with 5052 aluminum alloy, its lower limit of strength range is slightly lower.

In terms of yield strength, it is usually between 80-220MPa, and the elongation is generally between 10%-30%, which means that it has a certain strength and good plasticity, and can withstand tensile deformation to a certain extent without breaking. Its hardness is generally between HB65-HB85, and the specific value is affected by the heat treatment state.

Factors that lead to strength differences

The subtle role of alloy composition

The influence of magnesium content: Magnesium is the key alloying element of these two alloys. The magnesium content in 5052 aluminum alloy is 2.2-2.8%, while the magnesium content in 5754 aluminum alloy is 2.6-3.6%.

Although the magnesium content of 5754 aluminum alloy seems to be higher, the alloy performance is not determined solely by the magnesium content. The relatively high magnesium content in 5052 aluminum alloy makes its structure more compact and orderly when forming intermetallic compounds, thus slightly better in hardness performance. The magnesium content in 5754 aluminum alloy is relatively more evenly distributed, which is beneficial to the improvement of alloy toughness.

Synergistic effect of other elements: In addition to magnesium, the alloy also contains manganese, chromium, silicon and other elements. In 5052 aluminum alloy, the chromium content is 0.15-0.35%, and the manganese content is ≤0.10%. These elements work together with magnesium to improve the strength of the base metal and weld and reduce the tendency of welding cracks.

In 5754 aluminum coil, the silicon content is 0.40%, which is slightly higher than that of 5052 aluminum alloy. Silicon improves its forging performance and corrosion resistance, and affects the balance of strength and toughness, so that 5754 aluminum alloy has better comprehensive processing performance while maintaining a certain strength.

Heat treatment and processing technology

Differences in heat treatment state: Different heat treatment states will significantly change the properties of the alloy. In the annealed state, the 5052 aluminum alloy has good plasticity but relatively reduced strength; after cold work hardening, the strength is improved but the plasticity is reduced.

The 5754 aluminum alloy is similar, except that due to its alloy composition characteristics, the change range of strength and plasticity is different from that of the 5052 aluminum alloy under the same heat treatment process.

Influence of processing technology: Hot working and cold working processes also affect the strength of the two alloys. During hot working, the appropriate hot working process can optimize the internal structure of 5052 and improve the uniformity of strength. Proper control of 5754 aluminum alloy during hot working can enable it to meet specific strength requirements while maintaining good processing performance.

In terms of cold working, the performance change law of 5754 aluminum alloy under cold working state is different from that of 5052 aluminum alloy, which also leads to different strength performance under different cold working processes.

5754 5182 Automotive Aluminum Sheet

 At present, aluminum alloys for automobiles can be basically divided into die-casting aluminum alloys and deformed aluminum alloys, among which die-casting aluminum alloys are the main ones, accounting for about 66%.

Deformed aluminum alloys can be divided into rolled sheets (18%), extruded profiles (11%) and a small amount of forgings (5%). Automotive aluminum sheets are mainly used for body panels, including four doors and two covers (front and rear doors, hood, trunk lid), roof, fenders, etc.

Deformed aluminum alloys for vehicles mainly include 5xxx Al-Mg, 6xxx Al-Mg-Si and 7xxx Al-Zn-Mg. Among them, 5000 series aluminum alloys cannot be strengthened by heat treatment and have excellent formability. However, after forming, the yield point is likely to be extended and the surface will wrinkle.

5754 aluminum sheet belongs to Almg3. The magnesium alloy content is higher than that of the 5052 aluminum plate. 5754 aluminum plate is a medium-strength aluminum alloy plate with a magnesium alloy content of 2.6-3.6, with good rust and corrosion resistance. It has anodized surface with no color difference, excellent processability, excellent corrosion resistance, high fatigue strength, high weldability and moderate static strength, and is widely used in welded structures, storage tanks, pressure vessels, ship structures and offshore facilities, automobile manufacturing , transportation tanks, etc.

Due to the advantages of hardness and tensile strength, it has been used in a large amount in high-speed rail barrier panels in recent days. Usually 5754 aluminum plate will be processed into H111 or HO temper by annealing, because bending can only be done in this state. Of course, its price is higher than 5052 aluminum alloy plate.

Aluminum 5182 and 5754 are non-heat treated work-hardening Al-Mg alloys, mainly used for body structural parts and inner panels. The secondary phases in the alloys are Fe-rich and Mn-rich phases.

Undeformed Aluminum 5182 contains higher secondary phases and larger particle size than 5754 aluminum sheet. The percentages of the second phase in 5754 and 5182 were 0.60 % and 0.98 %, respectively. Welcome to leave message below to inquire what you need.

The Aluminum Alloy 5052 Used in Automotive Industry

 Different aluminum alloys have its own properties and is suitable for different parts of the car body. The lightweight and good processability and formability makes aluminum alloy sheet has been a key material of the car lightweight.

Although 5xxx aluminum alloy cannot be strengthened by heat treatment, it has good corrosion resistance and welding performance, which is mainly used for parts with complex shapes such as the inner panel of the car body. AcuraNSX uses aluminum alloy 5052 as the car body and 6000 series as the exterior panel, and JaguarXJ220 and GMEV1 use 5754 aluminum as the body cover material.

The main alloy element of 5052 aluminum sheet is magnesium, which has good forming properties, corrosion resistance, weldability, and medium strength. It can be used for automobile fuel tank, engine outer panels, trunks, car doors, etc., which can improve vehicle performance and decrease fuel consumption.

5052 aluminum plate has a higher strength-to-weight ratio than low-carbon steel. Therefore, 5052 aluminum plates are often used in larger squeezed areas of vehicles, which not only improves safety, but also improves performance. Firstly, the reduction in weight allows shorter stopping distances.Secondly, when comparing the strength-to-weight ratio of metals, 5052 aluminum can absorb the impact energy twice that of low-carbon steel. Therefore, the 5052 aluminum sheet can absorb the energy of the collision and help ensure the safety of passengers. This is extremely important in passenger cars.

Haomei 5052 aluminum alloy has good formability, smooth surface, good weldability and excellent bake hardenability. The lightweight of the automobile also requires the automotive aluminum sheet to have high bake hardenability, that is, the yield strength of the sheet after stamping deformation and paint baking has a significant increase.
