Steel is generally stronger than aluminum in terms of tensile strength, making it suitable for applications requiring high strength. อย่างไรก็ตาม, aluminum offers advantages such as being lightweight, ทนต่อการกัดกร่อน, and having superior electrical and thermal conductivity. It’s also easier to machine and is fully recyclable, which can make it more cost-effective and environmentally friendly. The choice between steel and aluminum depends on the specific needs of the application, balancing strength, weight, and other material properties.
