MOSCOW, July 25RUSAL has created a new alloy of the aluminum-silicon-magnesium system, whose durability is 12-15% higher than its global counterparts, and its strength is 5% higher; it is also used for high-speed trains, the company reported.
Rusal, one of the world's largest aluminum producers, has developed a new alloy of the aluminum-silicon-magnesium system… Alloys of the aluminum-silicon-magnesium system, due to their strength, fatigue life and manufacturability during pressing, are widely used in the car industry, including in most high-speed train models. Alloy 1343, thanks to its optimized chemical composition, has improved characteristics compared to analogues: fatigue life is 12-15% higher, strength is 5% higher,” says the press release.
The most important advantage of aluminum is that its use the design reduces the weight of the cars, which allows for some types of cargo to increase the commercial load of one car or increase the length of the freight train without additional traction, the message adds
It is noted that the aluminum body of the cars does not require anti-corrosion treatment. Unlike a steel case, therefore, the service life of an aluminum case is much longer. In addition, after the end of its service life, it is subject to 100% recycling and reuse in production, as follows from the company’s materials.
