After more than 30 years of development, China's hardware industry has become more mature and occupies an important position in the world market. At present, the output of many hardware products in China ranks first in the world, such as lighters, zippers, spanners, pliers, etc., which have good sales records abroad. At the same time, after years of development, the characteristics of the development of China's hardware industry cluster gradually highlighted.
China is one of the largest hardware producing countries in the world, and has become a big hardware processing and export country in the world, with broad market and consumption potential. With the development of social economy, hardware industry in the new situation, cluster development also has obvious characteristics.

Cold bending performance
It refers to some technological properties of whether a metal or alloy is suitable for casting, mainly including flow performance, mold filling capacity, shrinkage, volume shrinkage of castings during solidification, and segregation refers to the inhomogeneity of chemical composition.
It refers to the characteristics that two or more metal materials are welded together by heating or heating and pressure welding method, and the interface can meet the purpose of use.
It refers to the properties of metal materials that can bear bending without fracture at room temperature. The bending degree is generally expressed by the ratio of bending angle α (external angle) or bending center diameter D to material thickness a. the larger a or the smaller D / A, the better cold bending property of the material is.
The ability of metal materials to withstand stamping deformation without cracking. Stamping at room temperature is called cold stamping. The test method was cupping test.
Mechanical properties refer to the characteristics of metal materials under the action of external forces.
It refers to the properties that the material can withstand various processing and processing.
It refers to the resistance of metal materials to chemical or electrochemical reactions when they are in contact with surrounding media.
