Japan, Russia and Turkey submitted notices to the WTO concerning a list of compensation for U.S. tariffs on steel and aluminum imports. Russia submitted a total list of compensation of $538 million, while Japan and Turkey had a total list of $440 million and $267 million, respectively. The EU, China and India submitted a list of compensation totalling US$1.6 billion, US$612 million and US$165 million respectively.
For aluminum, although there is a trend of improvement in supply and demand, even considering the impact of environmental protection and production restrictions, the domestic supply and demand of electrolytic aluminum in 2018 is still 1.13 million tons. At present, aluminum prices are under pressure downward, electrolytic aluminum shipments at low prices are also relatively cold, holders are still interested in selling at a high price, and the downstream is to receive goods on demand, and the market transaction atmosphere is very general.
This may be why Zijin Mining and China's aluminum industry have seen a slight surge and fall under the stimulation of greater favors, and the future trend of copper and aluminum is indeed difficult to be smooth sailing.
Maglev vehicle aluminum and high-speed rail vehicles are basically the same, high-speed rail vehicles are made of aluminum, maglev train carriages should be made of aluminum, because the lighter the carriage, the better, the lighter the need to overcome the gravity to make it float up the less repulsion, the less power to fly, aluminum is the best cost-effective material for manufacturing vehicle structures, in addition to carriage aluminum, the construction of railway facilities also requires a considerable amount of building aluminum, carriage interior decoration, air conditioning and ventilation systems, etc. are also mainly made of aluminum, Some vehicles are floated with permanent magnet force, and if they float with a superconducting magnetic field, a high-purity aluminum wire system is required to deliver current. Each carriage needs to purchase 11.5t of aluminum, and the aluminum for railway facility construction can be calculated at 45t/km. The superconducting temperature of 4N6 high-purity aluminum is 4.2x10-3K, and the superconducting temperature of 99.5% industrial pure aluminum is 4.0x10-3K.
Commonly used body structure deformed aluminum alloys are: 5005-0 plate, 5005-H14 plate, 5005-H18 plate, 5052-0 plate, 5083-0 plate, 5083-H112 profile, 6061-T6 profile, 6N01-T5 profile, 6063-T5 profile, 7N01-T4 plate, 7N01-T5 profile, 7003-T5 profile. 6N01 and 7N01 are Japanese alloys, and N is short for Nippon (Japan).
China vehicle factories in the introduction of technology on the basis of digestion and absorption, in the vehicle design and manufacturing has a lot of innovation, the formation of Chinese characteristics of aluminum alloy manufacturing technology, but material manufacturers and colleges and universities, research institutes have not developed a new vehicle aluminum alloy with better performance than 6N01 and 7N01 alloy, which is a challenge to China's material community and metallurgical workers, must develop new aluminum alloy to adapt to the needs of faster, safer, more comfortable, more environmentally friendly vehicle manufacturing, Improve the competitiveness of maglev railways in the international market and accelerate the construction of the "Belt and Road".
