Railway Transportation Used Aluminum Alloy
The earliest railcars were made from cast iron and wood and they often suffered from serious corrosion effects. Today, railcars are made from aluminum alloy. DLS Aluminum can provide various aluminum alloys for railway transportation, and these materials offer the following advantages when applied in the railway transportation industry.
①Extremely high strength to weight ratio
Some aluminum alloys have higher strength but much lighter weight than steel. The efficiency of railway transportation is improved by reducing vehicle weight to a great extent.
②Extremely strong corrosion resistance
Vehicle durability is an important consideration when choosing materials for rail transport vehicles as they require a long service life. A thin alumina layer will be formed when aluminum is exposed to oxygen, which can prevent further oxidation of the metal. We can also improve corrosion resistance by anodizing.
③Good formability
Aluminum alloy has good formability. It can be easily processed into any shape, and all excess aluminum alloys can be recovered completely.
