Carbon steel pipe vs Aluminum alloy pipe

Carbon Steel

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218%-2.11%, also called carbon steel. Generally also contains small amounts of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and strength, but the lower the plasticity. According to the use, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel is further divided into two types: engineering construction steel and machine-made structural steel.

Aluminum Alloy
Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials. In addition to the general properties of aluminum, aluminum alloys also have some specific properties of alloys due to the different types and quantities of added alloying elements. The density of aluminum alloy is 2.63~2.85g/cm^3.

Aluminum alloy has high strength (σb is 110~650MPa), the specific strength is close to high alloy steel, the specific stiffness exceeds steel, has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and Weldable, it can be used as structural materials and is widely used in aerospace, aviation, transportation, construction, electromechanical, light weight and daily necessities.

Carbon steel pipe vs Aluminum alloy pipe: how to choose?

Carbon steel pipes are characterized by relatively high hardness and good wear resistance. They can be cut using equipment during use. In daily use and manufacturing process, the raw materials of cakes are easy to purchase, and the cost of production and processing is relatively low. Although carbon steel pipes have high hardness, their thermal hardness is very poor. Generally, when the temperature is greater than 200 degrees Celsius, the wear resistance and hardness will decrease.

Aluminum alloy pipes are characterized by relatively low density and are suitable for use in aerospace and vehicles. There is also a great demand in building decoration. It is very convenient to transport, can reduce costs in production, has a particularly wide range of uses, and has strong corrosion resistance. Aluminum alloys also have shortcomings. They are generally brittle and hard decoration materials, and their tensile strength is not very strong. It is not wear-resistant during use, has no impact resistance, is easily deformed when heated, and has poor stability.

Taken together, aluminum alloy pipes are suitable for occasions with higher requirements for weight and decoration, such as building facades, interior decoration, etc.; while carbon steel pipes are suitable for occasions with higher requirements for strength and durability. Such as steel structures, bridges, automobile parts, etc. Which material to choose needs to be comprehensively considered based on specific usage scenarios and needs.
