Commonly used materials for terminal connectors

Terminal Connectors

The commonly used materials for terminal connectors mainly include metallic materials and non-metallic materials.

Among metal materials, copper, aluminum, and steel are common choices. Copper has good electrical conductivity, corrosion resistance and plasticity, so it is widely used in the field of electrical appliances, such as home appliances, automobiles, ships and instrumentation. Common copper terminals include brass, phosphor bronze, beryllium bronze, and copper alloys. Aluminum terminals are lighter, stronger, and less expensive than copper terminal connectors, and are commonly used in high-voltage appliances, towers, and wires. Steel terminals are hard and wear-resistant, making them ideal for applications that require high strength and wear resistance, such as cutting machines, generators, and steel equipment.

Among the non-metallic materials, plastics and ceramics are also common terminal connector materials. Plastic terminals are usually made of materials such as nylon, polypropylene, etc., which have good insulation and corrosion resistance, and are often used in low-voltage circuits. Terminal connectors have excellent insulation and high temperature resistance, and can ensure no expansion and non-bursting even at high temperature and high pressure, so they are widely used in high-voltage cables, power equipment and other fields.

There are a variety of materials commonly used in terminal connectors, and the specific choice should be considered based on factors such as use case, performance needs, and cost.
