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.
