On the material of KBK aluminum alloy track

KBK aluminum alloy track is a kind of commonly used track for light load crane in industrial production line. It has the advantages of light weight and convenient operation. It is widely used in automobile production, new energy, shipbuilding and many other fields. Today, I will take you to explore the material of this kind of track, so that you can have a clearer understanding of why the aluminum alloy track is easy to use?

Aluminum alloy is one of the most widely used nonferrous metal structural materials in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts is increasing, so the research on the weldability of aluminum alloy is also in-depth. The wide application of aluminum alloy promotes the development of aluminum alloy welding technology, and the development of welding technology expands the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the research hotspots.

Pure aluminum has low density (ρ = 2.7g / cm3), about 1 / 3 of iron, low melting point (660 ℃), face centered cubic structure, so it has high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), easy processing, and can be made into various profiles and plates with good corrosion resistance; however, pure aluminum has low strength, and its annealing state σ b value is about 8kgf / mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually strengthen aluminum by adding alloy elements and using heat treatment methods, which leads to a series of aluminum alloys. The alloy formed by adding certain elements can maintain the advantages of pure aluminum, such as light weight, but also has high strength, σ b values can reach 24-60kgf / mm2. In this way, its "specific strength" (the ratio of strength to specific gravity σ B / ρ) is better than many alloy steels and becomes an ideal structural material. It is widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. The fuselage, skin and compressor of aircraft are often made of aluminum alloy to reduce the self weight. The structure weight can be reduced by more than 50% by using aluminum alloy instead of steel plate.

Therefore, the strength and other aspects of KBK aluminum alloy track using this material have very good advantages, and the operation and installation are very convenient.
