Stamping and processing technology is an integral part of the appliance manufacturing industry. It involves the use of molds and presses to press metal materials into parts of specified shapes and sizes. These parts are widely used in various household appliances such as refrigerators, washing machines, air conditioners, and so on. To ensure the performance and longevity of the appliance parts, it is vital to choose the right metal material.

Below are several metal materials commonly used in the stamping of home appliance parts and their characteristics:

1. Ordinary carbon steel: This is one of the most commonly used stamping materials with good plasticity and strength. Ordinary carbon steel is categorized into several grades according to its carbon content, such as Q235 and SPCC. They are relatively inexpensive, easy to process, and suitable for making parts that are not subject to high loads.

2. Stainless Steel: Stainless steel is favored for its excellent corrosion resistance and aesthetic appearance. In the home appliance industry, type 304 stainless steel is most commonly used because it resists daily corrosion and maintains the aesthetic appearance of the product. Stamping processing of stainless steel is difficult, requiring high-precision molds and professional processing technology.

3. Aluminum Alloy: Aluminum alloy is widely used in appliance parts for its light weight, high strength and good corrosion resistance. Common aluminum alloy materials include 5052, 6061, etc. They are not only lightweight, but also have good thermal conductivity, which makes them ideal for use in the manufacture of heat sinks and other components.

4. Copper and copper alloys: copper and copper alloys (such as brass H62, bronze, etc.) in home appliances are mainly used for electrical conduction parts. Copper has excellent electrical and thermal conductivity, while copper alloys offer more options for mechanical strength and corrosion resistance.

5. Nickel-silver alloys: These materials are commonly used in the manufacture of precision electrical contact parts because of their good electrical properties and resistance to soldering. Nickel-silver alloys are more economical than pure silver, while maintaining good electrical conductivity and low contact resistance.

6. Titanium and Titanium Alloys: Although more costly, titanium and its alloys are being used more and more widely in appliance parts, especially in high-end products. Titanium alloys have excellent strength, light weight and very high corrosion resistance for environments requiring high performance.

7. Galvanized steel: In order to improve the corrosion resistance of ordinary carbon steel, it is often galvanized. Galvanized steel provides additional protection against corrosion after stamping and is suitable for appliance parts in outdoor or wet environments.

Stamping of appliance parts involves the selection and application of a variety of metal materials. Each material has unique properties and applications, and the proper selection of metal materials is critical to ensuring the performance and longevity of your appliance.
