Fastener material knowledge

Fastener raw materials refer to the materials needed to manufacture fasteners.

Common fasteners include bolts, nuts, screws, studs, etc., which are usually made of metal, such as steel, stainless steel, aluminum alloy, etc.

The following are some common fastener raw materials and their characteristics:

1.Steel: Steel is the most common fastener material, because of its good strength and toughness and widely used. According to the specific use and requirements, you can choose different grades of steel, such as carbon steel, alloy steel, etc.

2 Stainless steel: Stainless steel has good corrosion resistance, suitable for fasteners used in wet or corrosive environments, such as Marine environment, chemical industry, etc. Common stainless steel materials are 304 stainless steel and 316 stainless steel.

3.Aluminum alloy: Aluminum alloy fasteners are often used in occasions that require lightweight materials, such as aerospace, automobiles, etc. Aluminum alloy has high strength and good corrosion resistance.

4.Copper: Copper fasteners are usually used for occasions that require good electrical conductivity, such as electronic equipment, electrical connections, etc. Copper has good electrical and thermal conductivity.

5.Titanium alloy: Titanium alloy fasteners have high strength and good corrosion resistance, and have the characteristics of light weight. Therefore, it is often used in high-demand fields such as aerospace and medical devices.

In addition, according to the specific use and requirements of fasteners, other special materials can be used, such as plastics, ceramics, etc.

It should be noted that the selection of fastener raw materials should be considered according to the specific engineering requirements and environmental conditions to ensure the stability and reliability of fasteners during use.
