The Differences Between Aluminum vs. Steel Fabrication


Steel is significantly more dense than aluminum, and it weighs far more than it. Auto makers and the aerospace industry are turning to parts made from aluminum to reduce energy consumption. Lightweight vehicles and aircraft have more efficient fuel use. Because of its relatively light capacity, this leads to more cost-effective aluminum transportation costs.

Physical strength

Although both aluminum and steel can be used as tough metals, steel is more harder. The device has a stronger carrying capacity, but also shows a better tensile resistance, especially when stretched, it is not easy to break. However, the ratio of aluminum strength to quality is even higher. Lighter aluminum offers greater structural stability than the same weight of steel.


Compared with steel, aluminum has significantly superior thermal conductivity and conductive characteristics. In the application of heat dissipation technology, the heat dissipation performance of aluminum far exceeds that of steel. However, steel material can more effectively cope with higher temperatures and does not easily soften.


The main production difference between aluminum and steel lies in its extenability, especially in the complexity of cutting, bending or folding of metal. Due to the density, thermal stability, and mechanical strength of steel, cutting or processing operations may encounter some challenges. Aluminum is easier to cut, bend or shape, although it becomes soft under heating conditions, a change that may pose some challenges in its manufacturing process.
