Classification of Nonferrous Metals<\/h2>\n
Nas aplica\u00e7\u00f5es pr\u00e1ticas, os metais n\u00e3o ferrosos s\u00e3o geralmente divididos em cinco categorias:<\/p>\n
- \n
- Light Metals (Density < 4.5g\/cm\u00b3): <\/strong>Aluminum, magnesium, potassium, sodium, calcium, strontium, barium, and the like.<\/li>\n
- Heavy Metals (Density > 4.5g\/cm\u00b3):<\/strong> Copper, nickel, cobalt, lead, zinc, tin, antimony, bismuth, cadmium, mercury, and the like.<\/li>\n
- Precious Metals: <\/strong> The price is higher than that of common metals, the abundance of the crust is low, the purification is difficult, and the chemical properties are stable, such as gold, silver, and platinum group metals.<\/li>\n
- Semi-metal: <\/strong>The property is between metal and non-metal, such as silicon, selenium, tellurium, arsenic, boron, and the like.<\/li>\n
- Rare Metals: <\/strong> Including rare light metals such as lithium, strontium, barium, etc. Rare refractory metals such as titanium, zirconium, molybdenum, tungsten, etc.; Rarely dispersed metals such as gallium, indium, antimony, etc. Rare earth metals such as lanthanum, cerium, and lanthanide metals. Radioactive metals such as radium, francium, polonium, uranium, thorium, and the like.<\/li>\n<\/ul>\n

Nonferrous Metals List<\/h2>\n
A China incluiu o ferro, o cr\u00f3mio e o mangan\u00eas na lista de metais ferrosos<\/strong> em 1958.<\/p>\n
Metais n\u00e3o ferrosos<\/strong> (exceto black metal 64 tipos de metal) incluem: alum\u00ednio, magn\u00e9sio, pot\u00e1ssio, s\u00f3dio, c\u00e1lcio, estr\u00f4ncio, b\u00e1rio, cobre, chumbo, zinco, estanho, cobalto, n\u00edquel, antim\u00f3nio, merc\u00fario, c\u00e1dmio, bismuto, ouro, prata, platina, rut\u00e9nio, r\u00f3dio, pal\u00e1dio, \u00f3smio, ir\u00eddio, ber\u00edlio, l\u00edtio, rub\u00eddio, c\u00e9sio, tit\u00e2nio, zirc\u00f3nio, h\u00e1fnio e van\u00e1dio, ni\u00f3bio, t\u00e2ntalo, tungst\u00e9nio, molibd\u00e9nio, g\u00e1lio, \u00edndio, t\u00e1lio, germ\u00e2nio, r\u00e9nio, lant\u00e2nio, c\u00e9rio, praseod\u00edmio, neod\u00edmio, sam\u00e1rio, eur\u00f3pio, gadol\u00ednio, t\u00e9rbio, dispr\u00f3sio, h\u00f3lmio, \u00e9rbio, t\u00falio, it\u00e9rbio e lut\u00e9cio, esc\u00e2ndio, \u00edtrio e t\u00f3rio<\/span>.<\/p>\n

Nonferrous Alloys: Enhanced Performance<\/h2>\n
When nonferrous metals combine with other elements (>50% base metal), they form superior alloys with:<\/strong><\/p>\n
- \n
- Higher strength & hardness<\/li>\n
- Improved temperature resistance<\/li>\n<\/ul>\n
Common Alloys Include:<\/strong><\/p>\n
- \n
- Aluminum alloys (aircraft components)<\/li>\n
- Copper alloys (brass, bronze)<\/li>\n
- Nickel superalloys (turbine blades)<\/li>\n<\/ul>\n
The strength and hardness of non-ferrous alloys are generally higher than those of pure metals; the electrical resistance is larger than that of pure metals, the temperature coefficient of resistance is small, and it has good comprehensive mechanical properties.<\/p>\n
As ligas n\u00e3o ferrosas normalmente utilizadas s\u00e3o as ligas de alum\u00ednio, as ligas de cobre, as ligas de magn\u00e9sio, as ligas de n\u00edquel, as ligas de estanho, as ligas de ni\u00f3bio, as ligas de tit\u00e2nio, as ligas de zinco, as ligas de molibd\u00e9nio, as ligas de zirc\u00f3nio e semelhantes.<\/p>\n

Critical Applications Across Industries<\/h2>\n
Uma vez que os metais raros s\u00e3o importantes na ind\u00fastria moderna, s\u00e3o por vezes separados dos metais n\u00e3o ferrosos e tornam-se numa \u00fanica classe. E justapostos aos metais ferrosos e aos metais n\u00e3o ferrosos, tornam-se as tr\u00eas grandes categorias de metais.<\/p>\n
Non-ferrous metals are not only the basic materials for the development of the national economy & people’s daily life, but also are essential materials and important materiais estrat\u00e9gicos<\/strong> for the national defense industry and the development of science & technology. Agricultural modernization, industrial modernization, national defense, and the modernization of science and technology are all inseparable from non-ferrous metals. For example, cutting-edge weapons such as airplanes, missiles, rockets, satellites, nuclear submarines, and the components or components required for cutting-edge technologies such as atomic energy, television, communications, radar, and electronic computers are mostly made of light metals and rare metals in non-ferrous metals; There are no non-ferrous metals such as nickel, cobalt, tungsten, molybdenum, vanadium and niobium, and there is no production of alloy steel.<\/p>\n

Atualmente, os metais n\u00e3o ferrosos tornaram-se uma base material importante para determinar o desenvolvimento da economia, da ci\u00eancia e tecnologia e da constru\u00e7\u00e3o da defesa nacional de um pa\u00eds. Trata-se de um recurso estrat\u00e9gico fundamental para aumentar a for\u00e7a global do pa\u00eds e salvaguardar a seguran\u00e7a nacional. Especialmente nos pa\u00edses industrializados, eles est\u00e3o a competir para desenvolver a ind\u00fastria de metais n\u00e3o ferrosos e aumentar as reservas estrat\u00e9gicas de metais n\u00e3o ferrosos.<\/p>\n
