Q1:

Can you make customized Aluminum Flange Plate according to our drawings?

A1:

Yes, full OEM and ODM services are available. We provide free DFM analysis to optimize your drawings for manufacturability and cost efficiency, ensuring the final Custom CNC Machined Aluminum Flange Plate meets your exact specifications.

Q2:

What aluminum alloy materials can you provide?

A2:

We offer 6061-T6, 6063-T5, 7075-T6, 5083-H112, and other custom aluminum alloys. 6061-T6 is our most popular choice for general industrial applications due to its excellent balance of strength, machinability, and corrosion resistance. 7075-T6 is recommended for high-strength aerospace and heavy-load applications.

Q3:

What tolerance and surface finish can you achieve?

A3:

We maintain ISO 2768-m general tolerances with IT7–IT9 precision for critical dimensions (±0.01 mm achievable). Surface roughness ranges from Ra 0.8–3.2 μm as standard, with Ra 0.4 μm available for high-precision mating surfaces. Flatness is controlled within ≤0.05 mm per 100 mm.
