Q1: What is a 7A03 aluminum ball?

A 7A03 aluminum ball is a precision sphere made from 7A03 (Al-Zn) alloy, typically supplied with heat treatment such as T6 to enhance mechanical properties. At Changzhou Eurasian, we ensure each ball meets strict dimensional and structural standards for high-performance applications.

Q2: Is 7A03 aluminum heat treatable?

Yes. High precision aluminum balls made from 7A03 can be supplied in T6 condition, which is a commonly requested thermal treatment for improved hardness and strength.

Q3: What sizes are available for 7A03 aluminum spheres?

Standard availability ranges from 1.000 mm to 150.000 mm, but actual supply depends on precision grade, order quantity, and manufacturing requirements. Our 7A03 aluminum balls manufacturing factory can produce custom sizes to meet specific project needs.

Q4: What precision grades can you supply?

We offer commonly used grades such as G100, G200, G500, and G1000. For specialized applications, custom aluminum balls can be produced according to drawing or sample specifications.

Q5: Are 7A03 aluminum balls corrosion resistant?

7A03 aluminum balls have good general corrosion resistance. However, in aggressive environments, pitting or stress corrosion may occur, so confirming the operating media is important.

Q6: Can you provide a passivated surface?

Yes. Passivated surfaces are available upon request, enhancing corrosion resistance and suitability for bearing, sealing, or decorative applications.

Q7: What information is needed to quote (RFQ)?

To provide an accurate quote, please supply diameter, quantity, precision grade (e.g., G200), heat treatment (e.g., T6), surface requirement (e.g., passivated), and intended application. We are also a reliable 7A03 aluminum balls seller, supporting both OEM and custom orders.
