The concept and classification of non-ferrous metals

Non ferrous metals usually refer to metals such as copper, aluminum, nickel, zinc, lead, tin, tungsten, magnesium, etc. They do not contain iron and have good conductivity, thermal conductivity, and corrosion resistance. They are widely used in the manufacturing of various products, such as wires, cables, pipelines, automotive parts, aerospace components, etc. Non ferrous metals play an important role in industrial production and daily life.

Nonferrous metals play an important role in industrial production and are widely used in the manufacturing of various metal products, such as copper products, aluminum products, zinc products, etc. Meanwhile, non-ferrous metals are also used in fields such as electronics, aerospace, and construction. Due to the special properties of non-ferrous metals, they have excellent performance in conductivity, thermal conductivity, corrosion resistance, etc., and are therefore widely used in various fields.

Copper is a non-ferrous metal.

Definition: Narrowly defined non-ferrous metals, also known as non-ferrous metals, are a collective term for all metals except iron, manganese, and chromium.

Broadly speaking, non-ferrous metals also include non-ferrous alloys. Nonferrous alloy is an alloy composed of a non-ferrous metal, a base metal (usually greater than 50%), and one or several other elements added.

Non ferrous metals usually refer to all metals except iron (sometimes manganese and chromium) and iron-based alloys.

Heavy metals;

Generally, the density is above 4.5g/cm3, such as copper, lead, zinc, etc;

Light metals;

Low density (0.53~4.5g/cm3), active chemical properties, such as aluminum, magnesium, etc.

Precious metals;

The content in the crust is low, extraction is difficult, the price is high, the density is high, and the chemical properties are stable, such as gold, silver, platinum, etc;
