What materials are suitable for using screws

　　The applicability of screws is closely related to the materials used. The following is a summary based on different material characteristics and application fields:

Brass:

　　Composition: Copper and zinc alloy composition.

　　Characteristics: It has good processing performance, electrical conductivity, and thermal conductivity.

　　Application: Widely used in fields such as home furnishings and construction.

　　Caution: Easy to corrode, especially in humid environments.

　　stainless steel:

　　Composition: Composed of iron, chromium, and other alloying elements.

　　Characteristics: It has corrosion resistance and high temperature resistance.

　　Application: Suitable for humid and highly corrosive environments, such as seawater and chemical industries.

　　Types: Common stainless steel screw materials include stainless steel 304 and stainless steel 316.

　　Attention: The cost is relatively high, but the service life is longer.

　　Carbon steel:

　　Composition: Mainly composed of iron and carbon.

　　Features: High strength, good wear resistance, and low cost.

　　Application: Suitable for general non corrosive environments.

　　Attention: It is prone to rusting. When used in damp or corrosive environments, coating treatment such as galvanizing or nickel plating is required.

　　aluminium alloy:

　　Features: Lightweight material with excellent thermal and electrical conductivity.

　　Application: Widely used in fields such as automobiles and electronic devices.

　　Attention: Compared with steel, aluminum alloy has lower strength and hardness, but is lightweight and has good corrosion resistance.

　　Titanium alloy:

　　Characteristics: Lightweight and high-strength material with corrosion resistance.

　　Application: Suitable for aerospace, chemical, marine and other environments.

　　Attention: The cost is high and the scope of application is limited.

　　High strength alloy steel:

　　Characteristics: It has high strength and corrosion resistance.

　　Application: Suitable for applications under high load and high temperature environments.

　　Attention: The specific alloy composition will affect its performance.

　　In summary, when selecting the material for screws, factors such as the corrosiveness of the working environment, temperature, and load should be considered. Materials such as brass, stainless steel, and carbon steel are widely used in different fields due to their respective characteristics. Stainless steel screws are highly favored for their excellent corrosion resistance in humid or corrosive environments; In situations where weight is required, such as in automobiles and electronic devices, aluminum alloy screws are widely used due to their lightweight characteristics.
