aluminum alloy is the most well -known aircraft aluminum alloy. When you need a alloy material with excellent intensity weight ratio, it is an ideal alloy. Aluminum has excellent strength and anti -fatigue, which makes it very suitable for application in the aerospace field.
The main alloy elements in the series of aluminum aluminum aluminum alloy aluminum alloy are copper. The standard is AMS or QQ-A-250/4 or GB/T -.Due to its high copper content, the corrosion resistance of is slightly lower. It usually uses or covers a layer of high -purity aluminum with anode oxidation surface to protect. Aluminum alloy has the characteristics of high strength and anti -fatigue, good processing, and good cutting. However, its corrosion resistance and weldingability are poor. When welding, it is usually vulnerable to the influence of thermal cracks and stress corrosion, and can only be welded, seam welded or flash welding.
The following are the best-selling products of aluminum alloy:
aluminum alloy is an aluminum alloy with zinc as the main alloy element. This makes have higher strength and higher strength weight ratio.Its standard is AMS-QQ-A-225/9 or GB/T-. aluminum is the lightest and strongest aluminum, as strong as steel, has good fatigue strength and average cutting processing. This is the key feature of aerospace, defense military industry and other industries. However, due to the high alloy component of aluminum, the hardness is extremely high. Therefore, welding and suppression are very difficult.
The following are the best-selling products of aluminum alloy:
Below is a comparison of some material properties between and aluminum alloys to highlight their differences. For ease of understanding, this article selects t3 VS t6, which are the most representative alloys for comparison.
In order to better analyze and understand these two types of aluminum alloys, we have summarized the following table ( vs Mechanical Properties), hoping to be helpful to you.
Material properties Yield strength 483 MPa 503 MPa Modulus of Elasticity 73.1 GPa 71.7 GPa Thermal conductivity 121-202 W/(m·K) 130-190 W/(m·K) Melting point 500 - 650°C 477 - 635°C Hardness (Brinell) 120-150HB 150-200HB Machinability Good FairThe yield strength of a material is called the maximum stress at which it begins permanent deformation. In contrast, the yield strength of aluminum is higher than that of aluminum. This allows 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 aluminum alloy.
Of course, the aluminum alloy industry should not be considered fragile, as its yield strength of 483 MPa is also much higher than most alloys.
It can be considered as the "stiffness" of an alloy; It measures the degree to which a material resists plastic deformation. Materials with higher modulus are considered more elastic because more work is required to permanently deform the material.
aluminum alloy has a higher elastic modulus than aluminum alloy (73.1 GPa vs 71.7 GPa), and when we compare the Young's tensile modulus of the two alloys, their values do not differ significantly.
Thermal conductivity is an indicator used to quantify the ability of a material to transfer or conduct heat. Usually, aluminum alloys are not used for insulation. This is because all forms of aluminum alloy are good thermal conductors. The chemical composition of two heat-treated aluminum alloys has a significant impact on their thermal conductivity.
In this case, the thermal conductivity of aluminum is slightly higher than that of aluminum (130-190 W/(m · K) vs 121-202 W/(m · K).Due to the high copper content in aluminum alloy, copper has a lower thermal conductivity, resulting in a lower overall thermal conductivity. The content of zinc and copper in aluminum alloy is relatively high, and zinc and copper have high thermal conductivity, therefore the overall thermal conductivity is relatively high.
Overall, aluminum alloy has higher thermal conductivity compared to aluminum alloy, which is very important in some situations that require rapid heat dissipation, such as high-speed engines and aircraft. However, in some applications that do not require high thermal conductivity, the thermal conductivity of aluminum alloy is sufficient, and its processing performance is relatively good, with lower costs. Therefore, it is necessary to choose appropriate aluminum alloy materials based on specific application scenarios and needs.
We analyzed the temperature resistance of t6 and t6 by comparing their melting points. The melting point of aluminum is slightly lower than that of aluminum (477-635 ° C vs 500-650 ° C). Therefore, alloy is more capable of withstanding higher temperatures than alloy. However, it should be noted that aluminum alloy exhibits excellent reaction to heat treatment. It can evenly distribute other alloy components in the metal.
aluminum is the highest strength to weight ratio among all aluminum alloys, therefore this alloy is mainly used in the aerospace and defense industries. The hardness of T6 aluminum is higher than that of T3 aluminum (150-200 HB vs. 120-150 HB). Compared with aluminum alloy, aluminum alloy has lower strength and toughness, but has better workability and weldability. Due to its excellent fatigue and corrosion resistance, it has been widely used in the aviation industry.
Overall, aluminum alloy has higher hardness and strength compared to aluminum alloy, but due to its poor processability and weldability, production costs are also higher. Therefore, in practical applications, it is necessary to choose appropriate materials based on specific circumstances. For many applications in the industry, its hardness is also sufficient.
aluminum alloy has good machinability and can be processed through various processes such as extrusion, stretching, casting, and deep drawing. However, cracks and deformation are prone to occur during the processing, requiring special process control and design.
aluminum alloy contains high zinc and copper elements, so it is easy to produce tool wear and riveting difficulties in the processing process. Therefore, the machinability of aluminum alloy is relatively poor, and special process control and design measures need to be taken, such as high-temperature processing and surface coating, to improve its machinability.
Overall, aluminum alloy has better machinability compared to aluminum alloy, but its strength and toughness are relatively low. aluminum alloy has higher strength and toughness, but its machinability is poor, and special measures need to be taken to improve its machinability. Therefore, in practical applications, it is necessary to choose appropriate materials and processing techniques based on specific circumstances to meet the requirements of the product.
aluminum alloy contains a high proportion of copper, therefore it has high strength and toughness, but relatively speaking, its corrosion resistance is poor. aluminum alloy is prone to corrosion in humid environment and is vulnerable to stress corrosion cracking. Therefore, in some applications that require high corrosion resistance, such as maritime navigation and coastal areas, aluminum alloy requires special corrosion protection measures.
aluminum alloy contains elements such as zinc, magnesium, copper, etc. The addition of these elements makes aluminum alloy have higher strength and better corrosion resistance. aluminum alloy is a high-strength and excellent corrosion resistance aluminum alloy material, which can be used in various applications that require high strength and corrosion resistance.
In summary, compared to aluminum alloy, aluminum alloy has better corrosion resistance. However, it should be noted that in some special environments, aluminum alloy still needs to take appropriate anti-corrosion measures to extend its service life.
aluminum is known to be more challenging to weld compared to other aluminum alloys due to its high copper content, which can lead to hot cracking and reduced weldability. It requires careful welding techniques and proper filler material selection to mitigate these issues. Additionally, aluminum can be prone to heat-affected zone (HAZ) cracking during welding, which requires precise control of welding parameters, such as heat input and travel speed, to minimize the risk of cracking.
On the other hand, aluminum is generally considered to have better weldability compared to aluminum. It is a heat-treatable alloy with lower copper content, which reduces the likelihood of hot cracking during welding. However, aluminum still requires proper welding techniques and control of welding parameters to ensure good weld quality. Preheating and post-weld heat treatment may also be required for certain welding applications to minimize the risk of cracking and optimize the mechanical properties of the welded joints.
In both cases, proper welding procedures, including thorough cleaning of the base material, appropriate filler material selection, careful control of heat input and travel speed, and consideration of post-weld heat treatment, can help achieve good welding performance for and aluminum alloys. It's important to follow established welding practices and consult relevant welding codes and specifications to ensure successful welding of these high-strength aluminum alloys.
