What are the characteristics of aluminum alloy profiles?
1/ Pure aluminum has low density (? = 2.7g/cm3), which is about 1/3 of iron, and has a low melting point (660℃). Aluminum has a face-centered cubic structure, so it has high plasticity (? :32~40%,? 70 ~ 90%), easy to process, can be made into various profiles and plates, and has good corrosion resistance; But the strength of pure aluminum is very low. Is it annealed? B value is about 8kgf/mm2, so it is not suitable for structural materials.
2/ Through long-term production practice and scientific experiments, people gradually strengthened aluminum by adding alloying elements and using heat treatment, and obtained a series of aluminum alloys. The alloy formed by adding some elements can maintain the advantages of pure aluminum, such as light weight, but also has high strength. The value of b can reach 24 ~ 60 kgf/mm2 respectively. Is that enough? Specific strength? (the ratio of strength to specific gravity? b/？ ) is superior to many alloy steels and becomes an ideal structural material. Widely used in machinery manufacturing, transportation machinery, power machinery and aviation industry. Aircraft fuselage, skin and compressor often use aluminum alloy to reduce their own weight. Replacing steel plate with aluminum alloy can reduce the structural weight by more than 50%.
More than ten brands of aluminum alloy profiles are explained. Because the quality of aluminum alloy profiles of different brands is different, only the aluminum alloy profiles of big brands can better meet people's demand for after-sales protection when purchasing aluminum alloy profiles. The performance of aluminum alloy profiles is also mentioned above. Before using each profile, you need to know something about performance.
