The material of hardware terminals is usually a metal material with good electrical conductivity, stable mechanical properties and certain corrosion resistance. Common hardware terminal materials include the following:
Brass: Brass is a copper-zinc alloy with good electrical conductivity and processability, and its cost is relatively low. Brass terminals are widely used in electrical connections, especially where particularly high conductivity is not required.
Phosphor Bronze: Phosphor bronze is a copper-tin-phosphorus alloy with excellent elasticity, wear resistance and corrosion resistance. Phosphor bronze terminals perform well in environments that require frequent plugging and unplugging or vibration, and are often used for precision electrical connections.
Pure Copper: Purple copper is pure copper with extremely high electrical and thermal conductivity. Copper terminals are suitable for applications requiring high electrical conductivity, such as power transmission and large electrical equipment.
Stainless Steel: Stainless steel is an alloy steel with excellent corrosion resistance. Stainless steel terminals perform well in humid, corrosive environments, but have relatively poor electrical conductivity, so they are more commonly used for mechanical connections or protective structures.
Tin-Plated Copper: Tin-Plated Copper is an alloy material with a layer of tin plated on the copper surface. Tin-plated copper terminals increase the corrosion resistance of the surface while maintaining the conductive properties of copper. They are suitable for occasions that require good conductivity and certain corrosion resistance.
Silver: Silver is a precious metal with excellent electrical conductivity. Although silver terminals have extremely high electrical conductivity, they are more expensive and are therefore more used for high-end, precision electrical connections.
