In many fields such as industrial manufacturing, automobiles, aerospace, and sports equipment, the strength and performance of materials determine the quality and application life of products. As two widely used lightweight materials, the strength comparison between carbon fiber and aluminum alloy has always been the focus of attention of engineers and purchasers. This article will systematically compare the strength performance of carbon fiber and aluminum alloy from four aspects, and introduce why more and more companies choose to cooperate with carbon fiber product suppliers such as Revolve CF to use high-performance carbon fiber products instead of traditional metal materials.
The tensile strength of carbon fiber is usually above 3500 MPa, while the tensile strength of aluminum alloy (such as 6061-T6) is generally 310 MPa. In other words, the strength of carbon fiber is about 10 times that of aluminum alloy.
The density of carbon fiber is 1.6g/cm³, while the density of aluminum alloy is about 2.7g/cm³. While achieving the same or even higher strength, carbon fiber can significantly reduce the overall weight.
As can be seen from the table, the specific strength of carbon fiber is more than 20 times that of aluminum alloy. This is also an important reason why high-end equipment widely uses carbon fiber materials.

In the structure of spacecraft and drones, carbon fiber has stronger fatigue resistance and higher rigidity, and can maintain a stable deformation rate during long-term operation to avoid structural loosening.
Carbon fiber frames and shells can provide better energy absorption and protection performance in collision tests, and are more suitable for manufacturing high-performance body structural parts than aluminum alloys.
High-performance sports equipment such as racing car shells, bicycle frames, tennis rackets, and skis generally use carbon fiber instead of aluminum alloy because of its higher strength and stability.
Carbon fiber can strengthen the mechanical properties of a certain direction according to the different fiber direction arrangements, which is difficult for isotropic materials such as aluminum alloys to do.
Carbon fiber products have excellent fatigue resistance and are not prone to crack propagation, especially for parts that bear cyclic loads.
The thermal expansion coefficient of carbon fiber is close to zero, and its dimensions are stable in high-temperature environments, while aluminum alloys are prone to thermal expansion and contraction, affecting structural accuracy.

Carbon fiber composite materials can be made into complex shapes such as hollow, curved, and curved surfaces through prepreg layering, RTM molding, hot pressing molding and other processes to meet customized needs.
Carbon fiber products can be formed into lightweight and high-strength components through structural bonding or mechanical riveting, which are more suitable for use in large equipment or carrier systems.
The surface of carbon fiber can achieve 3K woven texture, bright matte treatment, spraying, transfer and other appearance effects, which not only has strength but also has beauty.
Carbon fiber has the characteristics of corrosion resistance, UV resistance, and aging resistance. Compared with aluminum alloy, it is more suitable for long-term use in extreme environments.
Through comparison, it can be seen that carbon fiber products have comprehensively surpassed traditional aluminum alloy products in terms of tensile strength, specific strength, thermal stability and fatigue life. For companies pursuing high-performance and high-reliability products, choosing carbon fiber is not only a trend, but also a key step to enhance competitiveness.
