Aluminum alloy sheets for railcars have higher necessities for comfort and aesthetics, which has promoted using many new substances. In line with the improvement of mainstream low-floor railcars our bodies, the materials used in the frame shape are from a single weathering steel/carbon steel, stainless steel, a combination of aluminum sheet to a spread of materials, and regularly use new substances. Compared with different vehicles, the railcars has the benefits of fast, huge transportation, protection, punctuality and reliability. It solves the problem of city traffic congestion and substantially facilitates human beings's travel, has produced substantial social blessings.
Aluminum plays an essential function in rail transit. Aluminum alloy sheets for railcars have first-rate advantages including mild weight, high energy and desirable corrosion resistance, making them very broadly used in the field of railcar transit. On common, every EMU desires to apply 9 heaps of aluminum alloy, each subway, light rail, and concrete specific rail desires to use 6.Five lots of aluminum alloy, and every railcar wishes to use four.5 lots of aluminum sheet alloy. Presently, the commonly used aluminum sheet for railcars transit include 3003 aluminum plates, 5052 aluminum plates and 6061 aluminum plates.Aluminum alloy sheets for railcars is widely used within the manufacture of rail transit cars due to its blessings of low density, high energy, high rigidity,and smooth processing. But, the corrosion resistance and appearance ornament overall performance of aluminum alloy sheet is not excessive, and it typically requires surface treatment strategies together with oxidation, chromization and portray to enhance the corrosion resistance and look ornament of aluminum alloy sheet products.
