High-purity polished tantalum balls for semiconductor chemical processing and aerospace applications — PRODUCT REFERENCE / FINAL SPECIFICATION BY QUOTATION

PRODUCT OVERVIEW

What are tantalum balls?

Tantalum balls are dense refractory-metal spheres produced from high-purity tantalum. A stable passive oxide film gives tantalum exceptional resistance to many aggressive chemical environments, while its high melting point supports demanding thermal and vacuum-related programs.

Buyers should specify purity, diameter, tolerance, surface finish, cleanliness and certificate requirements. Suitability depends on the exact chemical medium, concentration, temperature, pressure, electrical duty and contamination limits.

PRODUCT FAQ

Answers for engineering and purchasing teams.

What purity is available for tantalum balls?

≥99.95% tantalum is a typical reference. Higher-purity requirements should be stated with the analytical method and certificate expectations.

What sizes and tolerances can be supplied?

The reference range is 0.5–100 mm with ±0.01 mm as a typical project tolerance. Actual capability depends on purity, diameter, quantity and finish.

Are tantalum balls suitable for chemical processing?

Tantalum resists many aggressive media, but every application must be checked against the exact chemical, concentration, temperature, pressure and exposure time.

Can you supply polished or high-cleanliness tantalum spheres?

Yes. Machined, ground, lapped and polished surfaces plus cleanliness and protective packing can be reviewed before quotation.

Are tantalum spheres used in electronics?

Tantalum is important in capacitors and other high-value electronic systems. The ball application, purity, dimensions and qualification evidence must be defined by the buyer.

How should tantalum balls be specified?

State purity, diameter, tolerance, surface finish, cleanliness, quantity, application, packing and required material or inspection certificates.

Can you provide material certificates and inspection reports?

Yes. State the required certificate, inspection method, sampling plan and report format before quotation so documentation can be included in the supply plan.

Do you support samples and small-quantity orders?

Yes. SDBALLS Industry Corp. supports North American prototype, qualification, repair, R&D and small-batch requirements, subject to material, size and production availability.
