Classification of Nonferrous Metals<\/h2>\n
Dans les applications pratiques, les m\u00e9taux non ferreux sont g\u00e9n\u00e9ralement divis\u00e9s en cinq cat\u00e9gories :<\/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
La Chine a class\u00e9 le fer, le chrome et le mangan\u00e8se parmi les substances suivantes m\u00e9taux ferreux<\/strong> en 1958.<\/p>\n
M\u00e9taux non ferreux<\/strong> (\u00e0 l'exception du m\u00e9tal noir 64 sortes de m\u00e9tal) comprennent : aluminium, magn\u00e9sium, potassium, sodium, calcium, strontium, baryum, cuivre, plomb, zinc, \u00e9tain, cobalt, nickel, antimoine, mercure, cadmium, bismuth, or, argent, platine, ruth\u00e9nium, rhodium, palladium, osmium, iridium, b\u00e9ryllium, lithium, rubidium, c\u00e9sium, titane, zirconium, hafnium et vanadium, niobium, tantale, tungst\u00e8ne, molybd\u00e8ne, gallium, indium, thallium, germanium, rh\u00e9nium, lanthane, c\u00e9rium, pras\u00e9odyme, n\u00e9odyme, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium et lut\u00e9cium, scandium, yttrium et thorium.<\/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
Les alliages non ferreux couramment utilis\u00e9s sont les alliages d'aluminium, les alliages de cuivre, les alliages de magn\u00e9sium, les alliages de nickel, les alliages d'\u00e9tain, les alliages de niobium, les alliages de titane, les alliages de zinc, les alliages de molybd\u00e8ne, les alliages de zirconium, etc.<\/p>\n

Critical Applications Across Industries<\/h2>\n
Les m\u00e9taux rares \u00e9tant importants dans l'industrie moderne, ils sont parfois s\u00e9par\u00e9s des m\u00e9taux non ferreux et deviennent une classe unique. Juxtapos\u00e9s aux m\u00e9taux ferreux et aux m\u00e9taux non ferreux, ils constituent les trois grandes cat\u00e9gories de m\u00e9taux.<\/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 mat\u00e9riaux strat\u00e9giques<\/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

Aujourd'hui, les m\u00e9taux non ferreux sont devenus une base mat\u00e9rielle importante pour d\u00e9terminer le d\u00e9veloppement de l'\u00e9conomie, de la science et de la technologie d'un pays, ainsi que la construction de la d\u00e9fense nationale. Il s'agit d'une ressource strat\u00e9gique essentielle pour renforcer la puissance globale du pays et pr\u00e9server la s\u00e9curit\u00e9 nationale. Les pays industrialis\u00e9s, en particulier, sont en concurrence pour d\u00e9velopper l'industrie des m\u00e9taux non ferreux et augmenter les r\u00e9serves strat\u00e9giques de m\u00e9taux non ferreux.<\/p>\n
