Nearly pure copper balls, they show good mechanical and corrosion resistance properties, excellent thermal and electric conductivity.

Small amounts of alloying elements as Cr, Zr, Ag, Cd, Mg, Sn allow to improve the mechanical properties.

Copper balls are used in galvanic applications and in the field of electronic industry.

Good corrosion resistance in marine and industrial atmospheres, steam, alkali, neutral saline solutions. They do not resist in contact with oxidizing acids, halogens, sulphides, ammonia, sea water.

FAQ – Copper Balls (Solid & Hollow)

Q1: What are the main advantages of copper balls?

Copper balls provide excellent electrical and thermal conductivity, good corrosion resistance in many environments, and high ductility for forming or machining. They also maintain an attractive surface appearance after polishing, making them suitable for both functional and decorative applications.

Q2: What are copper balls typically used for?

Solid and hollow copper balls are commonly used in electrical and electronic components, switches, connectors, printed circuits, and power distribution equipment where good conductivity is important. They are also applied in valves, float assemblies, instrumentation, precision devices, jewelry, and decorative projects. Eurasian specializes in copper precision ball manufacturing to meet high-quality requirements.

Q3: What is the difference between solid and hollow copper balls?

Solid copper balls are heavier and stronger, ideal for electrical, mechanical, and precision uses requiring mass, strength, or accurate dimensions. Hollow copper balls are much lighter and often used where weight reduction, buoyancy, or decorative appearance is prioritized. For larger-scale applications, large copper ball and large solid copper ball options are available, while small copper balls or tiny copper balls suit compact assemblies.

Q4: In which environments are copper balls suitable, and where are they not recommended?

Copper balls have good corrosion resistance in many atmospheric, marine, and industrial environments and perform well in contact with steam, alkalis, and neutral salt solutions. They are not suitable for strong oxidizing acids, halogens, sulfides, ammonia, or very aggressive chemical media.

Q5: What is a copper float ball and where is it used?

A copper float ball is typically a hollow sphere mounted on a rod or threaded spud and used with a float valve to control liquid levels in tanks and reservoirs. Applications include water tanks, boilers, industrial process tanks, and other systems requiring automatic liquid level regulation.

Q6: How do I choose between solid and hollow copper balls for my project?

Choose solid copper balls when mechanical strength, electrical or thermal conductivity, weight, or precise dimensions are important. Hollow copper balls are ideal when low weight, buoyancy, or decorative effect is the main priority, such as float balls, art pieces, or architectural assemblies. Customers can also source from a solid copper ball supplier for tailored solutions or solid copper balls for sale in various sizes.

Q7: What information do you need to recommend or quote copper balls?

Provide the type (solid or hollow), diameter, tolerance or precision grade, quantity, and a brief description of the application. Any special requirements, such as surface finish, drilling or threading, coating, or export packaging, should also be included for an accurate recommendation.

Q8: How is the quality of copper balls controlled?

Copper balls are manufactured from high-purity copper through forming, machining, or spinning (for hollow types), followed by heat treatment, polishing, and cleaning. Dimensions, roundness, surface finish, and, when applicable, conductivity and corrosion resistance are checked to ensure each batch meets the specified performance.
