What kind of work is most used in the machinery industry? What are the metallic materials used in machining? Let Dongguan jiaxin precision machinery Co., Ltd. to tell you the key!

1, pig iron and cooked iron: pig iron refers to an iron alloy containing carbon bonds between 2 % and 4.3 %. The cooked iron is a purer iron refined from pig iron and contains less than 0.02 % carbon.

2, pig iron and cast iron: cast iron is a kind of pig iron, refers to the pig iron that can be used for casting, usually refers to ductile iron.

3, the performance of carbon steel is related to the carbon containing site, the higher the carbon content, the greater the hardness, but the worse the toughness; The lower the carbon content, the better the toughness, but the less the hardness.

4, the difference between the color of pure iron and iron in daily life Daily life, we are generally in contact with iron is not pure iron, but some iron oxides or iron-containing mixture, so our common iron color is black, but it is not The color of pure iron, The color of pure iron is silver-white.

After the metal is fused with other metals or non-metals, not only the composition has changed, but also its internal structure has changed, causing changes in nature. Therefore, alloys have a wider use than pure metals. Comparison of properties of pure metals and alloys:

Alloys are generally more brightly colored than their constituent metals.

The hardness of the alloy should generally be composed of its metal.

3, the melting point of the alloy is generally lower than the metal into which it is made.

The corrosion resistance of an alloy is generally compacted to make up its metal.

The conductivity and thermal conductivity of an alloy are generally inferior to the metal that makes up it.
