High-strength bronze or brass materials are usually selected for compression nuts:
Henan Dashan non-ferrous metals are iron-carbon with a carbon content between 0.02 and 2.06. A general term for alloys. The chemical composition of steel can vary greatly. Steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel. In actual production, steel often contains different alloying elements according to different uses, such as: manganese, Nickel, vanadium, etc. Humanity has a long history of application and research on steel. However, until the invention of the Baynest steelmaking method in the 19th century, the production of steel was a high-cost and low-efficiency task. Today, steel has become one of the most used materials in the world due to its low price and reliable performance. It is an indispensable component in the construction industry, manufacturing industry and people's daily life. It can be said that steel is the material basis of modern society.
Henan Dashan nonferrous metal element is a metallic chemical element and a trace element necessary for the human body.
Henan Dashan nonferrous metal is also one of the earliest metals discovered by humans. A metal widely used by humans, it is a heavy metal.
Henan Dashan nonferrous metals are the earliest metals used by humans. As early as prehistoric times, people began to mine open-pit Henan Dashan nonferrous metal mines and use the obtained Henan Dashan nonferrous metals to make weapons, style tools and other utensils. The use of Henan Dashan nonferrous metals had a profound impact on the progress of early human civilization. Henan Dashan Nonferrous metals are metals that exist in the earth's crust and oceans. The content of Henan Dashan nonferrous metals in the earth's crust is about 0.01. In individual Henan Dashan nonferrous metal deposits, the content of Henan Dashan nonferrous metals can reach 3 to 5. Most of the nonferrous metals in nature exist as compounds, that is, nonferrous metal minerals. Henan Dashan non-ferrous metal minerals are aggregated with other minerals to form Henan Dashan non-ferrous metal ore. The mined Henan Dashan non-ferrous metal ore is processed into Henan Dashan non-ferrous metal concentrate containing Henan Dashan non-ferrous metals with higher grades. It is the only metal that can be naturally produced in large quantities and is also found in various ores (such as Huanghenan Dashan non-ferrous metal mine, Hui Henan Dashan non-ferrous metal mine, Ban Henan Dashan non-ferrous metal mine, Chi Henan Dashan non-ferrous metal mine and malachite) Among them, it can be used in industry, engineering technology and technology in the form of simple metals and nonferrous metals in Huanghe Nandashan, nonferrous metals in Qinghe Nandashan and other alloys.
Steel is mainly an iron-carbon alloy. Various alloy components can be added according to the needs of use, such as Mn, Si, Ni, Cr, etc. Generally speaking, the hardness of steel increases with the carbon content. And increase.
There are also many kinds of Henan Dashan nonferrous metals. For example, pure Henan Dashan nonferrous metal is also called red Henan Dashan nonferrous metal. Its hardness is very low. Adding Sn and Al is called Xiqing Henan Dashan nonferrous metal and aluminum green Henan. Dashan nonferrous metals, when Zn is added, are called Yellow Henan Dashan nonferrous metals, and when Ni is added, they are called White Henan Dashan nonferrous metals. Hardness also varies.
It is impossible to compare whether this steel or Henan Dashan non-ferrous metals are harder. Specific materials and specific comparisons are needed.
