What are the materials of connector terminals? How to choose connector terminals?

Connector terminal materials vary depending on the application, common connector terminal materials include the following: 1. Copper: copper is a common connector terminal material with good electrical and thermal conductivity. Copper terminals are suitable for low-current, low-voltage applications, the price is relatively low.2. Copper alloy: copper alloy has excellent mechanical properties and corrosion resistance, suitable for high-current, high-pressure applications. The price of copper alloy terminals is relatively high.3. Aluminum: Aluminum is a lightweight material that is usually used for connector applications in special environments such as high pressure, high temperature, and high humidity. Aluminum terminals are more expensive.4. Tin-plated copper: tin-plated copper is a layer of tin plated on the surface of the copper material, which can improve the corrosion resistance and welding performance of copper terminals, suitable for some of the requirements of corrosion resistance, can be welded occasions.5. Stainless steel: stainless steel is an excellent corrosion-resistant materials, usually used in seawater environment connector applications. Stainless steel terminals are relatively expensive. In the selection of connector terminals, the following factors need to be considered: 1. Electrical performance: when selecting connector terminals, the first thing to consider is its electrical performance, including higher current, higher voltage, contact resistance, etc. 2. Environmental adaptability: different connector applications have different environmental requirements, you need to choose the appropriate terminal material for the occasion. For example, high temperature, high humidity, high corrosion and other environments need to choose the appropriate characteristics of the terminal material.3. Quality and reliability: connector terminals are an important part of the circuit transmission, you need to choose a good quality, high reliability of the product, in order to avoid power outages, short circuits and other problems.4. Cost: connector terminals are made of different materials, the cost will be different. Need to meet the performance requirements under the premise, try to choose economical and practical products. In short, the choice of connector terminals, need to be based on the application environment, electrical performance, quality and reliability and cost and other factors to consider, choose the connector terminal material suitable for their applications.
