Changzhou Eurasian offers a full range of hollow and hollow copper ball products, including solid copper balls and hollow copper balls, designed for industrial, electrical, and decorative applications. Our copper spheres are known for excellent conductivity, corrosion resistance, and machinability, making them ideal for electronics, valves, fuel injectors, and artistic designs.

Advantages of Solid Copper Balls

Solid copper balls provide consistent density and excellent mechanical properties. They offer:

• High electrical and thermal conductivity for electronic and electrical applications.

• Good corrosion resistance in industrial and marine atmospheres.

• Ease of machining, allowing drilling, tapping, and surface cutting.

• Durability for repeated use in valves, gauges, and transmission systems.

As a trusted solid copper ball supplier, Changzhou Eurasian ensures precise dimensions, polished surfaces, and uniform material properties for consistent performance.

Features of Hollow Copper Balls

Hollow copper balls combine lightweight construction with the same electrical and corrosion-resistant properties as solid spheres. These balls are ideal for decorative, artistic, and specialized industrial applications where weight reduction is critical. Changzhou Eurasian, as a hollow copper ball exporter, provides hollow spheres in various sizes with precise wall thickness and surface finish.

Materials and Specifications

Changzhou Eurasian’s copper balls are made of nearly pure copper (T2, C1100, C11000) with small alloying elements such as Cr, Zr, Ag, Cd, Mg, and Sn to enhance mechanical properties. Key specifications include:

• Size range: 1mm–60mm.

• Grade: G100, G200, G500, G1000, G2000.

• Hardness: HV40–120.

• Magnetic properties: Nearly non-magnetic.

• Surface treatments: Polishing, electroplating, and other finishing options.

These specifications ensure suitability for galvanic applications, electrical components, marine equipment, and decorative uses.

Applications of Hollow and Solid Copper Balls

Hollow and solid copper balls have versatile industrial and functional uses:

• Electrical components: Switches, connectors, and carburetors.

• Machinery parts: Valves, fuel injectors, sprayers, pressure gauges, and water meters.

• Decorative items: Jewelry, bracelets, earrings, necklaces, and art pieces.

• Industrial and marine environments: Resistant to alkali, neutral saline solutions, and steam; not suitable for oxidizing acids or halogens.

• Precision manufacturing: Ideal for drilling, tapping, and machining due to soft but durable material properties.
