2406022386 有色金属是指除了铁和铁基合金以外的所有金属。它们通常被分为以下几类：

• 轻金属：密度小于4500千克/立方米，如铝、镁、钾、钠、钙、锶、钡。

• 重金属：密度大于4500千克/立方米，如铜、铅、锌、锡、钴、镍、锑、汞。

• 贵金属：价格昂贵，化学性质稳定，如金、银、铂、铱、锇、钯、铑、钌。

• 稀有金属：包括稀有轻金属（如锂、铍）、稀有难熔金属（如钛、锆、钼、钨）、稀有分散金属（如镓、铟、锗、铊）以及稀土金属（如钪、钇、镧系元素）

有色金属在工业和日常生活中有着广泛的应用，例如在航空、航天、汽车、电子、建筑和医疗等领域都非常重要。它们用于制造各种设备、构件、电线、电池和装饰品，也是许多高科技产品的关键材料

Non ferrous metals refer to all metals except iron and iron-based alloys. They are usually divided into the following categories:

Light metals: with a density of less than 4500 kilograms per cubic meter, such as aluminum, magnesium, potassium, sodium, calcium, strontium, and barium.

Heavy metals: with a density greater than 4500 kilograms per cubic meter, such as copper, lead, zinc, tin, cobalt, nickel, antimony, and mercury.

• Precious metals: expensive and chemically stable, such as gold, silver, platinum, iridium, osmium, palladium, rhodium, and ruthenium.

Rare metals: including rare light metals (such as lithium and beryllium), rare refractory metals (such as titanium, zirconium, molybdenum, tungsten), rare dispersed metals (such as gallium, indium, germanium, thallium), and rare earth metals (such as scandium, yttrium, and lanthanide elements)

Nonferrous metals have a wide range of applications in industry and daily life, such as in aviation, aerospace, automotive, electronics, construction, and medical fields. They are used to manufacture various devices, components, wires, batteries, and decorations, and are also key materials for many high-tech products
