Types and characteristics of fastener raw materials

Fasteners are commonly used in industrial production of a connection parts, it includes bolts, screws, nuts and other types. As a wide variety of raw materials for fasteners, each material has its own unique characteristics and scope of application.

 
1. Stainless Steel
Stainless steel is a material with strong corrosion resistance, and has good corrosion resistance due to the formation of a dense oxide film on its surface. Stainless steel fasteners have long-term stable connection performance in humid, high temperature or corrosive environments. In addition, stainless steel materials also have high strength, can meet a variety of industrial needs, suitable for use in a variety of harsh environments.

2. Carbon steel
Carbon steel is an economical and practical fastener material with good strength and toughness. Carbon steel fasteners are often used in general structures and mechanical equipment, and their price is relatively low, suitable for mass production. However, it should be noted that carbon steel is prone to oxidation in humid and corrosive environments, so surface treatment, such as galvanizing or heat treatment, is required. Carbon steel fasteners have the characteristics of high strength, low price, easy processing, etc., and are widely used in construction engineering, machinery manufacturing and other fields.

3. Copper
Copper is a material with good electrical conductivity and excellent electrical and thermal conductivity. Copper fasteners are often used in situations where electrical conductivity is required, such as electronic equipment and communication equipment. In addition, copper has good corrosion resistance and can maintain stability in humid environments for a long time. However, the strength of copper is relatively low, generally suitable for some light load occasions, widely used in electronic equipment manufacturing, electrical engineering and other fields.

 
4. Aluminum alloy
Aluminum alloy is a kind of high strength, light weight, good corrosion resistance fastener raw materials, with good mechanical properties and corrosion resistance. Aluminum alloy fasteners are widely used in automotive, aerospace and light industry, which can reduce the weight of equipment and improve the overall performance. However, aluminum alloy is relatively soft and prone to deformation, so it is necessary to pay attention to the control of fastening strength.

Summary
There are many kinds of raw materials for fasteners, and each material has its own characteristics and application fields. According to the actual needs, the selection of the appropriate fastener raw materials is very important to ensure the quality and stability of the connection. By choosing the right fastener raw materials, you can improve work efficiency, reduce maintenance costs, and ensure the fastness and stability of the connection, so as to provide better solutions for various industries.
