Strength characteristics of aluminum alloy shell
The strength of aluminum alloy casing is quite good compared to many materials, and it has many advantages, making it widely used in electronic products, transportation, building structures and other fields. However, the assessment of strength needs to consider the specific aluminum alloy type and its application scenario.
Excellent tensile strength and rigidity:
The mechanical properties of aluminum alloys can be greatly improved through alloying treatment (such as adding zinc, magnesium, copper and other elements). The tensile strength of some high-strength aluminum alloys can even approach that of some low-carbon steels.
Light Weight:
Compared to steel, the density of aluminum alloy is only about one-third of that of steel, which achieves a good balance between strength and weight and is an ideal choice for lightweight design.
Strong corrosion resistance:
Aluminum alloy can form a dense aluminum oxide protective layer in the natural environment, which helps to resist oxidation and corrosion and extend the service life.
For example: the one-piece aluminum die-cast brake components are resistant to brake oil, and the [network communication transmitter] installed outdoors is resistant to salt spray and acid and alkali.
Good impact resistance:
Aluminum alloy has good toughness and can absorb impact to a certain extent to avoid structural damage.
Example: Electric motor housing
Excellent processing performance:
Aluminum alloy is easy to process into complex shapes and is also easy to carry out surface treatment (such as anodizing) to enhance the hardness and wear resistance of the shell.
For example: Transmission oil pan
Limitations to note:
Lower hardness:
Although the strength of aluminum alloys can be improved, their hardness is generally lower than that of steel, making them more susceptible to surface scratches or dents.
For example: it is ductile and the presence of ribs does not affect the structure.
Poor high temperature resistance:
The mechanical properties of aluminum alloys will drop significantly at high temperatures, making them unsuitable for use in extremely high temperature environments.
For example: Development object usage assessment.
The strength of the aluminum alloy housing is sufficient for most daily applications, and is especially suitable for situations where lightweight and corrosion resistance are required.
However, if extreme hardness is required or if it withstands extreme environments, other materials or special treatments may be necessary.
