Jul 24, 2018

Copper in non-ferrous metals is one in every of the earliest metal materials utilized by humans. Modern, non-ferrous metals and their alloys became indispensable structural materials and purposeful materials within the fields of machinery producing, construction, natural philosophy, part and atomic energy.

In sensible applications, non-ferrous metals area unit usually classified into 5 categories: one. lightweight metals. 2. serious metals. 3. Precious metals. 4. Semi-metal. 5. Rare metals.

Non-ferrous metals usually confer with all metals except iron (and typically metal and chromium) and iron-based alloys. Non-ferrous metals will be divided into four categories:

1. serious metals: the overall density is on top of four.5g/cm3, cherish copper, lead, zinc, etc.;

2. lightweight metal: density (0.53 ~ 4.5g / cm3), with chemicals active, cherish atomic number 13, atomic number 12 then on.

3. Precious metals: less content within the crust, troublesome to extract, high price, high density, stable chemical properties, cherish gold, silver, platinum, etc.;

4. Rare metals: cherish metallic element, molybdenum, niobium, lithium, antimony, uranium, etc.

Because rare metals area unit necessary in trendy trade, they're typically separated from non-ferrous metals and become one category. And close with metallic element metals and non-ferrous metals, it becomes the 3 major classes of metals.
