Most Common Uses of Aluminum | Metal Supermarkets - …
9/5/2016· High-speed rail systems like the Shinkansen in Japan and the Maglev in Shanghai also use aluminum. The metal allows designers to reduce the weight of the trains, cutting down on friction resistance. Aluminum is also known as the ‘winged metal’ because it is ideal for aircraft; again, due to being light, strong and flexible.. In fact, aluminum was used in the frames of Zeppelin airships

Silicon carbide (SiC) has been found to occur naturally only as small green hexagonal plates in metallic iron. The same form of silicon carbide has been manufactured synthetically, however. In this process, SiO 2 sand is mixed with coke in a large elongated mound in which large carbon electrodes have been placed at either end.
Regarding China''s export licensing system for certain forms of bauxite, coke, fluorspar, manganese, silicon carbide, and zinc, the Panel found that the system is not per se inconsistent with China''s obligations under Article XI:1 of the GATT 1994.27 However, the
