contact material

Connector is consist of 2 parts: insulator and contact.

Normally there are two kinds of material of the contact, one is brass and another is phosphor bronze.

Phosphor bronze

Phosphor bronze is an alloy of copper with 0.5–11% of tin and 0.01–0.35% phosphorus. The tin increases the corrosion resistance and strength of the alloy. The phosphorus increases the wear resistance and stiffness of the alloy.It offer a reliable for the connectors


Brass is a common IDE material, with good electrical conductivity, which is widly used on low-cost connectors. But it’s performance will get degraded after using.

How to choose the contact material is subjected to the connector type, performance, circumtance, electrial, cost and other facts. SYM provides the reasonable option for the connector on your decison
