With the development of science and technology, the requirements for metal contact center components are gradually increasing, and the demand is gradually increasing. Therefore, the demand for technology that can produce high-precision and high-quality metal parts is also increasing. As a stable, efficient and high-quality manufacturing process, metal parts stamping has become one of the most versatile and popular manufacturing processes in the world today.
In addition to advanced custom sheet metal stamping technology and metal stamping tools, it is also important to select suitable raw materials and automation technology. Each metal and alloy has different characteristics. It is very important for stamping parts manufacturer to understand key information about the most common metals that can be used in the metal stamping process. In this article we will introduce in detail the characteristics of the three most common raw materials.
1. Copper Alloy
Copper alloys include a variety of materials, such as brass and bronze. Because copper alloys contain different proportions of copper, they have good properties of copper, such as electrical conductivity, corrosion resistance and antibacterial properties.
The corrosion resistance of copper and copper alloy stamping parts is very good, because an oxide layer is quickly formed on the surface during the finishing or forming process, which protects the copper alloy parts and makes them more resistant to corrosion. In addition, copper alloys are available in a variety of colors, which makes copper alloy parts more decorative.
However, copper and copper alloys are too soft for stamping die components that require high strength or are used as support structures. Metal that is too soft is easy to bend, crack or even break, but its softness is also conducive to metal forming. Due to the excellent ductility of copper and copper alloys, their forming and a&i metal stamping are relatively easy, which means that copper alloys can achieve relatively complex designs and accurately replicate the original designs.
2. Steel Alloy
The main components of steel alloys are iron and carbon, which are one of the most commonly used raw materials in metal stamping. Steel is a dense and strong metal. Many metal stamping parts manufacturer like this alloy because of its strength and versatility. Moreover, steel alloys can be added with other metals to increase specific physical properties.
Compared with other alloys, steel alloys can be processed into stamping steel parts using several different manufacturing processes, which also makes the production steps of steel parts more flexible and changeable and has a wider range of applications. At the same time, the price of steel alloy is lower, which is an economical choice.
Steel is very strong, so you need to choose a suitable metal stamping process. The metal is treated before or after the stamping process to increase hardness or make parts corrosion resistant. Stainless steel is a special alloy that can resist corrosion, but other steel alloys need to be galvanized to prevent rust and damage. Designers and engineers also need to carefully weigh the advantages of steel in terms of strength and the disadvantages of weight when designing.
3. Aluminum Alloy
The quality of aluminum alloy is lighter than the first two alloys, which makes aluminum stamping parts very suitable for structures that require strength without additional load, or structures that need to be transported. In addition, the electrical and thermal conductivity of aluminum alloys are good. And because a dense oxide layer is formed on the surface, the corrosion resistance of aluminum alloy is quite excellent. However, aluminum alloys are more expensive than similar steel alloy materials.
