Metales no ferrosos

What Are Non-Ferrous Metals?

In the narrow sense, the nonferrous metals refer to all metals except iron, manganese, and chromium. In a broad sense, non-ferrous metals also include non-ferrous alloys. Non-ferrous alloys are composed mainly of non-ferrous metal (usually greater than 50%) and contain one or more other elements.
Nonferrous metals are valued for their unique properties that outperform those of ferrous metals in many industrial applications.

Key Characteristics of Nonferrous Metals:

• Corrosion resistant
• Excellent conductivity (heat & electricity)
• Lightweight (for some types)
• Non-magnetic
• Malleable and ductile

Classification of Nonferrous Metals

En la práctica, los metales no férreos suelen dividirse en cinco categorías:

• Light Metals (Density < 4.5g/cm³): Aluminum, magnesium, potassium, sodium, calcium, strontium, barium, and the like.
• Heavy Metals (Density > 4.5g/cm³): Copper, nickel, cobalt, lead, zinc, tin, antimony, bismuth, cadmium, mercury, and the like.
• Precious Metals: 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.
• Semi-metal: The property is between metal and non-metal, such as silicon, selenium, tellurium, arsenic, boron, and the like.
• Rare Metals: 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.

Nonferrous Metals List

China incluyó el hierro, el cromo y el manganeso como metales ferrosos en 1958.

Metales no ferrosos (excepto black metal 64 tipos de metal) incluyen: aluminio, magnesio, potasio, sodio, calcio, estroncio, bario, cobre, plomo, zinc, estaño, cobalto, níquel, antimonio, mercurio, cadmio, bismuto, oro, plata, platino, rutenio, rodio, paladio, osmio, iridio, berilio, litio, rubidio, cesio, titanio, circonio, hafnio y vanadio, niobio, tántalo, wolframio, molibdeno, galio, indio, talio, germanio, renio, lantano, cerio, praseodimio, neodimio, samario, europio, gadolinio, terbio, disprosio, holmio, erbio, tulio, iterbio y lutecio, escandio, itrio y torio..

Nonferrous Alloys: Enhanced Performance

When nonferrous metals combine with other elements (>50% base metal), they form superior alloys with:

• Higher strength & hardness
• Improved temperature resistance

Common Alloys Include:

• Aluminum alloys (aircraft components)
• Copper alloys (brass, bronze)
• Nickel superalloys (turbine blades)

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.

Las aleaciones no ferrosas comúnmente utilizadas son aleaciones de aluminio, aleaciones de cobre, aleaciones de magnesio, aleaciones de níquel, aleaciones de estaño, aleaciones de niobio, aleaciones de titanio, aleaciones de zinc, aleaciones de molibdeno, aleaciones de circonio y similares.

Critical Applications Across Industries

Como los metales raros son importantes en la industria moderna, a veces se separan de los metales no férreos y se convierten en una sola clase. Y yuxtapuestos con los metales ferrosos y los metales no ferrosos, se convierten en las tres grandes categorías de metales.

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 materiales estratégicos 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.

En la actualidad, los metales no ferrosos se han convertido en una importante base material para determinar el desarrollo de la economía, la ciencia y la tecnología y la construcción de la defensa nacional de un país. Es un recurso estratégico clave para aumentar la fuerza integral del país y salvaguardar la seguridad nacional. Especialmente en los países industrializados, compiten por desarrollar la industria de metales no ferrosos y aumentar las reservas estratégicas de metales no ferrosos.
