Aluminum Alloy Balls supplied by SDBALLS — PRODUCT REFERENCE / FINAL SPECIFICATION BY QUOTATION

PRODUCT OVERVIEW

What are aluminum alloy balls?

Aluminum alloy balls are lightweight metal spheres supplied as solid, hollow or machined components depending on diameter and function. Their low density, non-magnetic behavior and finish options support applications where steel is unnecessarily heavy.

Alloy, temper and manufacturing method determine strength, corrosion performance and machinability. The buyer should specify solid or hollow construction, alloy, diameter, wall thickness, surface and load.

PRODUCT FAQ

Answers for engineering and purchasing teams.

Are aluminum balls solid or hollow?

Both are possible depending on size and method. State construction and wall thickness because performance differs significantly.

Can aluminum balls be anodized?

Yes, subject to alloy, surface preparation, color, masking and cosmetic acceptance.

Are aluminum balls suitable for bearings?

Generally not for high-load precision bearings because aluminum is softer than bearing steel. They suit lightweight and low-load mechanisms.

Can you machine threads or holes?

Yes. Provide a drawing with alloy, thread standard, datum, tolerance and surface finish.

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.
