Aerospace, ships, railways, MRT, light rail, buses, automobiles, trains -- each form of transportation contains many different components. These components are related to human life and safety, meaning there is no margin for error. When choosing materials within these industries, special attention must be paid to whether the material has properties such as fire resistance, corrosion resistance, and heat resistance.

Take a car as an example. A car is mainly composed of components made of metal and non-metal materials. However, metals are prone to oxidation and corrosion, which not only affects the appearance of the product, but more importantly poses a threat to safety. Naturally, national laws and regulations require that a car must undergo corrosion resistance testing, and even goes into details like whether the wiper placed on the car windshield affects the driver’s line of sight. When selecting materials for these products, there must also be anti-corrosion and resistance to temperature differences considered.
