A tantalum ball (also called a tantalum sphere or Ta ball) is a high-performance metal sphere made from tantalum, a refractory metal known for exceptional corrosion resistance, chemical stability, and high-temperature capability. Tantalum spheres are widely used in harsh chemical environments, vacuum systems, medical and laboratory equipment, and specialized industrial components where stainless steel balls may fail.
Our tantalum balls can be supplied in custom diameters, tight tolerances, and multiple surface finishes. Material certificates and dimensional inspection reports are available upon request, supporting reliable sourcing for R&D, prototype builds, and volume production.

Our manufacturing and quality systems are certified to IATF 16949:2016 and other international standards, which are widely recognized by global automotive and precision industries. This allows us to apply strict automotive level process control to aluminum balls and other industrial balls, ensuring stable performance batch after batch.
Eurasian has long experience in producing high precision chrome steel, stainless steel, and carbon steel balls, supported by CQI9based heat treatment and advanced inspection equipment. The same metallurgical and process expertise is applied when developing and manufacturing aluminum balls, so you benefit from consistent hardness, microstructure, and dimensional accuracy across all materials.

From bearing steel balls (GCr15 / AISI 52100) to stainless steel, aluminum, carbon steel, and special balls, Eurasian can support multiple projects and platforms with one consolidated supply base. This helps you simplify supplier management, align quality standards, and reduce total procurement and logistics costs.
Eurasian supplies precision balls for automotive seat systems, wheel bearings, industrial equipment, and other export applications through long term cooperation with overseas customers. Our team is familiar with international documentation, packaging, and inspection requirements, making your aluminum ball sourcing smoother and more predictable.
With established production lines and daily capacity measured in tons, we can support both trial orders and large volume programs with reliable delivery times. Flexible MOQs, customized packaging, and responsive communication help you introduce aluminum balls into new projects while controlling risk and lead time.

Tantalum balls are used where high corrosion resistance, chemical stability, and high-temperature performance are required, such as chemical valves, pump components, vacuum systems, and laboratory instruments.
Some buyers use “tantalum bearing balls” as a search term, but tantalum is usually chosen for corrosion resistance or high-temperature environments rather than conventional high-speed bearings. If you share your load/speed conditions, we can confirm suitability.
Custom diameters are supported. Please send your required size (mm or inch), tolerance, and quantity, and we will quote accordingly.
Yes, high purity tantalum is available. We can also provide a material certificate (MTC) to confirm chemical composition.
Yes. We can supply tantalum precision balls with specified diameter tolerance and surface finish. Share your drawing/spec and inspection method requirement.
Tantalum generally offers significantly better resistance in many aggressive chemical environments where 304/316 may corrode. Actual performance depends on the chemical media, concentration, and temperature, so we recommend confirming your exact conditions.
Tantalum is essentially non-magnetic in practical applications (paramagnetic), making it suitable where magnetic interference must be minimized.
Common options include ground and polished finishes. For high-purity or vacuum applications, cleaner packaging and surface handling can be specified.
We can provide dimensional inspection reports and material documentation. If you need specific standards, sampling plans, or full inspection, tell us before ordering.
MOQ and lead time depend on size, tolerance, and purity requirements. Prototypes and small batches are typically possible; send your specs for an accurate schedule.
