Metal pin terminals are key components in electronic connectors, and the
choice of their materials directly affects the performance and life of the
connectors. Common materials are as follows:
1. Brass: Brass is a copper-zinc alloy with good electrical conductivity
and mechanical properties. After surface treatment (such as gold plating, silver
plating), brass pin terminals can provide reliable electrical connections in
general environments.
2. Phosphor bronze: Phosphor bronze is a copper-tin alloy that contains a
small amount of phosphorus and has excellent elasticity and corrosion
resistance. Phosphor bronze pin terminals are often used in applications that
require higher elasticity and durability.
3. Beryllium bronze: Beryllium bronze is a high-performance material with
extremely high strength, elasticity and conductivity. Beryllium bronze pin
terminals are often used in connectors with high-density and high-speed signal
transmission.
4. Stainless steel: Stainless steel has excellent corrosion resistance and
mechanical strength, and is suitable for connectors in harsh environments.
5. Aluminum: Aluminum and its alloys are often used in pin terminals for
high-current applications due to their light weight and good electrical
conductivity.
6. Precious metals such as silver and gold: These materials are usually
used as surface coatings to improve conductivity and oxidation resistance.
