Thumbtacks are a common office supply and handicraft, widely used in various fields. Its design is simple but practical, with different materials and characteristics. This article will compare different materials of thumbtacks and their characteristics, so that readers can better understand their application scenarios and choose the appropriate material.

Comparison of Different Materials of Thumbtacks:

1. Iron Thumbtacks: Iron thumbtacks are the most common type, with a low price and durability. Their surface is usually coated to enhance their rust and wear resistance. However, iron thumbtacks are prone to rusting, especially in a humid environment. 2. Copper Thumbtacks: Copper thumbtacks have good electrical conductivity and thermal conductivity, strong corrosion resistance, and are not easy to rust. In addition, the appearance of copper thumbtacks is usually more exquisite, often used in handicrafts and decorations. 3. Steel Thumbtacks: Steel thumbtacks have high hardness and strength, as well as wear and corrosion resistance. Their design is precise, allowing for the creation of various complex shapes. They are often used in situations where greater force is required, such as sewing, embroidery, etc. 4. plastic thumbtacks: Plastic thumbtacks are lightweight, durable, and low-cost, often used in children's toys, writing instruments, etc. In addition, due to their good insulation properties, they are also used in certain electronic products. However, the downside of plastic thumbtacks is that they are prone to breaking. Application Scenarios of Different Materials of Thumbtacks: 1. Iron thumbtacks are usually used in general office occasions and handicraft production. 2. Copper thumbtacks are often used in the production of high-end handicrafts and decorations. 3. Steel thumbtacks are widely used in situations where greater force is required, such as sewing, embroidery, etc. 4. plastic thumbtacks are mostly used in the production of lightweight items such as children's toys and writing instruments.
