What are the materials of rivets?

Rivets come in a variety of materials to meet different application scenarios and needs. Here are some common rivet materials:

1. Steel: Steel rivets have high strength and hardness, suitable for riveting occasions under large loads. The price of steel rivets is relatively low, and it is one of the most widely used rivets materials.

2. Aluminum alloy: Aluminum alloy rivets have the characteristics of light weight, high strength, corrosion resistance, etc., and are often used in the manufacturing of aircraft, automobiles, trains and other transportation vehicles. The disadvantage of aluminum rivets is that the tensile strength and corrosion resistance are relatively poor.

3. Stainless steel: Stainless steel rivets have corrosion resistance, high temperature resistance, wear resistance and other characteristics, suitable for food, medicine, aviation and other strong corrosive environment occasions. However, stainless steel rivets may also produce hydrogen embrittlement, and the steel performance is not as good as carbon steel.

4. Copper: Copper rivets have good electrical conductivity and corrosion resistance, suitable for riveting occasions requiring good electrical conductivity and corrosion resistance. Common copper rivets are brass rivets, red copper rivets and copper rivets.

5. Plastic: Plastic rivets, such as nylon rivets, made of nylon or other plastic materials. They have the advantages of insulation, corrosion resistance, lightweight, etc., and are often used in electronic equipment, automotive interior and other occasions.

6. Composite materials: Some special applications may use composite rivets, such as carbon fiber composite rivets, which combine the advantages of a variety of materials, with high strength, light weight, corrosion resistance and other characteristics.

When selecting rivet material, it is necessary to consider factors such as the material, working environment, load requirements and cost of the riveted part. Rivets of different materials have different characteristics and scope of application, and the correct selection of riveting materials is crucial to ensure riveting quality and extend service life.

In addition, there are some special treatment of rivets, such as electroplated rivets, by plating a layer of metal (such as nickel, chromium, etc.) on the surface of the rivets to improve its corrosion resistance, wear resistance and aesthetics. This treatment is very useful in situations where the surface properties of rivets need to be improved.
