The difference between brass terminals and tin-plated terminals

I. Materials

The brass terminals are made by mixing copper and zinc and other metals. The tin-plated terminals, on the other hand, are made of specially treated stainless steel or copper materials, with a tin coating applied to enhance their conductivity and corrosion resistance.

II. Corrosion Resistance

The tin-plated terminals have a better corrosion resistance because the tin coating on their surface can prevent oxidation and corrosion. However, the brass terminals require special anti-corrosion treatment to achieve the same effect.

III. Conductivity

The brass terminals have higher conductivity because they are directly made of copper. While the tin-plated terminals have relatively poorer conductivity due to the tin coating applied on their surface.

IV. Cost

The brass terminals have a higher cost because they use more pure copper materials. However, the tin-plated terminals have a lower material cost and thus a more affordable price, making them more accessible.

In conclusion, the brass terminals and the tin-plated terminals differ in materials, corrosion resistance, conductivity, and cost. In practical applications, it is necessary to choose the appropriate connector based on specific requirements to enhance the stability and safety of the circuit.
