Mechanical Properties Of Aluminum Extruded Tubes
Dec 15, 2024
The mechanical properties of aluminum extruded tubes mainly include strength, plasticity, hardness and toughness. These performance indicators are of great significance for the application of aluminum extruded tubes.
Strength
The strength of aluminum tubes refers to the maximum stress they can withstand under stress. The strength of aluminum tubes is related to factors such as its material, wall thickness, and outer diameter. Generally speaking, the strength of aluminum alloy tubes is higher than that of pure aluminum tubes.
For example, the tensile strength of 7075 aluminum alloy extruded tubes is ≥560 MPa, the yield strength is ≥505 MPa, and the hardness is between 150-200 HB.
Plasticity
The plasticity of aluminum tubes refers to their ability to deform under stress. The plasticity of aluminum tubes is related to factors such as their material, temperature, and stress rate. Generally speaking, aluminum tubes have good plasticity and can withstand a certain degree of deformation.
Hardness
The hardness of aluminum tubes refers to their ability to resist pressure under stress. The hardness of aluminum tubes is related to factors such as their material, strength, and heat treatment. Generally speaking, the hardness of aluminum tubes is lower than that of ordinary steel, but higher than that of pure aluminum tubes.
Toughness
The toughness of aluminum tubes refers to their ability to withstand impact loads under stress. The toughness of aluminum tubes is related to factors such as its material, strength, and temperature. Generally speaking, aluminum tubes have good toughness and can withstand a certain degree of impact loads.
Influencing factors
The mechanical properties of aluminum extruded tubes are affected by many factors, including:
Material: Aluminum alloys of different materials (such as 6061, 7075, etc.) have different mechanical properties.
Heat treatment: Heat treatment processes such as solution treatment and artificial aging can significantly affect the strength and hardness of aluminum tubes.
Processing technology: Manufacturing processes such as extrusion, stretching, and rolling have an important influence on the mechanical properties of aluminum tubes.
Application scenarios
Due to their good mechanical properties, aluminum extruded tubes are widely used in industries and construction. For example:
Industrial pipelines: Pipeline systems used to transport fluids or gases.
Building structure: Used to make frames and support structures for buildings.
Automobile Manufacturing: Used in the manufacture of automobile parts, such as body frames, engine components, etc.
