Metal manufacturing industry includes functional metal manufacturing manufacturing, metal materials special tools manufacturing, Marine Containers metal packaging materials manufacturing, stainless steel plate similar daily necessities metal manufacturing manufacturing. With the development of society science technology, the application of metal manufacturing in industrial production, agriculture animal husbandry people's daily life is becoming more more common, which also brings about more more use value for social development.

Definition of metal material manufacturing industry

According to the 2013-2019 Sales Market Research Report of China's gray ferrous metal mining processing industry released by the market research management center, it is analyzed that metal materials are chemical substances with glossiness, plasticity, easy conductivity heat transfer. The individual characteristics of metal materials are related to the free charge in the metal crystal. In nature, most of the metal materials exist in the combined state, a few metal materials such as gold, platinum, silver bismuth in the pipe cutter exist in the free state. Metal materials minerals are mostly metal oxides sulfates. Other forms of storage are fluoride, potassium thiocyanate, sulfide aluminosilicate. The mutual connection between the metal materials is the metal key, so the pipe cutting software can create the mutual connection again if any parts are removed replaced, which is also the reason for the excellent plasticity of metal materials. Chemical elements generally only show positive valence in chemical substances. The laser tube cutting with high relative molecular weight is called heavy metal exceeding the standard.

Key classification of metal material manufacturing industry

Light metals: iron, chromium manganese.

Rare metals: aluminum, magnesium, lutetium, scandium, yttrium, thorium.

Such as iron, aluminum, etc.

Nonferrous Metals: such as zirconium, hafnium, niobium, tantalum, etc.

Nonferrous Metals: relative density less than 4500kg / m3, such as titanium, aluminum, magnesium, potassium, sodium, calcium, strontium, barium, etc.

Heavy metals exceed the standard: the relative density exceeds 4500kg / m3, such as copper, nickel, cobalt, lead, zinc, tin, antimony, bismuth, cadmium, mercury, etc.

Precious metals: compared with common metals, the price of precious metals is high, the abundance of the earth's interior is low (also known as the clarkevalue), which indicates the average composition of chemical molecules in the earth's interior, the purification is difficult, such as gold, silver platinum group metals.

Quasi chemical elements: the characteristic valence of metal materials non-metallic materials, such as silicon, selenium, tellurium, arsenic, boron, etc.

Non ferrous metals: including rare non-ferrous metals, such as lithium, rubidium, cesium, etc;

Rare silicide metal materials: such as zirconium, molybdenum, tungsten, etc;

Rare dispersed metal materials: such as gallium, indium, germanium, thallium, etc;

Rare earth metals: such as scandium, yttrium, lanthanide metal materials;

Radioactive metals: such as radium, francium, polonium uranium thorium in actinides.
