In modern industry and electronics, the choice of materials directly affects product performance and service life. Copper balls (Pure Copper Balls), with their excellent electrical conductivity, good ductility, and stable chemical properties, have become an indispensable component across multiple sectors.

1. Key Advantages of Copper Balls

1. Outstanding Electrical Conductivity
   With an electrical conductivity of up to 97% IACS (International Annealed Copper Standard), copper ranks among the best conductive materials. Copper balls ensure minimal energy loss in circuits, electronic components, and conductive mechanisms.

2. Excellent Ductility
   Copper balls maintain strength and toughness even under cold working conditions, making them suitable for precision machining and complex structural designs.

3. Corrosion Resistance and Stability
   Copper naturally forms a protective oxide film in the air, providing resistance to oxidation and corrosion. This ensures long-term stability and reduced maintenance costs during use.

4. High Thermal Conductivity
   Beyond electrical performance, copper also offers superior thermal conductivity, making copper balls highly effective in heat dissipation applications such as electronic devices and cooling systems.

2. Typical Applications of Copper Balls

1. Electronics and Electrical Industry
   Widely used in contact points, electronic components, and conductive switches to ensure reliable current transmission.

2. Electromagnetic Shielding & Communication Equipment
   Copper balls deliver excellent conductivity and shielding effects, widely applied in EMI protection and communication electronics.

3. Precision Instruments
   Copper balls provide both mechanical support and efficient electrical signal transmission in sensors and high-precision devices.

4. New Energy & Automotive Industry
   With the rise of electric vehicles and energy storage systems, copper balls are increasingly used in battery connections and conductive components to improve overall efficiency.
