2024 vs 7075 aluminum alloy

2024 aluminum alloy and 7075 aluminum alloy are common aviation aluminum

2024 aluminum alloy is a typical hard aluminum alloy – aluminum-magnesium-copper series aluminum alloy, containing 4.5% copper, 0.6% manganese, and 1.5% magnesium. It has reasonable composition and good overall performance. 2024 aluminum sheet also has high strength and certain heat resistance, and can be used as working parts below 150°C.

When the temperature is higher than 125°C, its strength is higher than that of 7075 aluminum plate. It has better formability under thermal tempering, annealing and new quenching conditions. The heat treatment strengthening effect is significant, but the heat treatment process requires strict requirements.

Performance Comparison

Both 7075 and 2024 belong to the aviation aluminum family, but their specific alloying elements set them apart, 7075 contains a higher proportion of zinc and copper, which gives it excellent strength. On the other hand, 2024 contains a large amount of copper, which enhances its machinability.

1. Strength

7075 aluminum is known for its superior strength and is one of the strongest aluminum alloys currently available. In contrast, 2024 has good strength, but still not as good as the amazing strength of 7075.

2. Yield Strength

The yield strength of a material is referred to as the maximum stress at which the material begins to deform permanently. In contrast, the yield strength of 7075 aluminum sheet plate is higher than that of 2024 aluminum. This allows 7075 aluminum to withstand higher impacts and pressures for a period of time without deformation. It is determined by the chemical composition and heat treatment of the 7075 aluminum alloy.

3. Machinability

Although 7075 aluminum has high strength, its machinability is poorer than 2024. The high zinc and copper content in 7075 leads to its low machinability.

2024 has a higher copper content, is easier to process, and has better formability.

4. Corrosion resistance

Due to its high copper content, 2024 aluminum alloy has higher strength and toughness, but relatively speaking, its corrosion resistance is poor.

7075 aluminum alloy contains zinc, magnesium, copper and other elements. The addition of these elements makes 7075 aluminum alloy have higher strength and better corrosion resistance. 7075 aluminum alloy is a high-strength and excellent corrosion-resistant aluminum alloy material, which can be used in various occasions requiring high strength and corrosion resistance.

5. High temperature resistance

We analyze their high temperature resistance by comparing the melting points of 7075 T6 and 2024 T6. The melting point of 7075 aluminum is slightly lower than that of 2024 aluminum (477-635°C vs 500-650°C). Therefore, 2024 alloy can withstand higher temperatures than 7075 alloy.

Casting production process and its introduction

The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.

Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.

Hot rolling production process and its introduction

  • 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
  • 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
  • 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
  • 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
    • Hot rolling equipment

      Casting and rolling process

      Casting and rolling process: liquid metal, front box (liquid level control), casting and rolling machine (lubrication system, cooling water), shearing machine, coiling machine.

      • 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
      • 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
      • 3. The production speed is generally between 1.5m/min-2.5m/min;
      • 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
        • Cold rolling production process

          • 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
          • 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
          • 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
          • 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
            • Casting rolling

              Introduction to finishing production process

              • 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
              • 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
              • 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.

Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxic, easy to recycle, excellent electrical conductivity, heat transfer and corrosion resistance, so it has a wide range of applications.
