High Precision Super Flat Aluminum Plate 6061 7075 5052 5083
Shenzhen Chinalco Metal supplies super flat aluminum plates in grades like 5083, 6061, 7075，5052 with precision surface and tight flatness tolerance.
High-Precision Super Flat Aluminum Plate Features
Outstanding Dimensional Stability
Exceptional machining stability ensures minimal deformation during processing, maintaining tight tolerance and high precision throughout the operation.Ultra-High Flatness
Surface flatness can reach 0.05mm to 0.1mm, making it ideal for precision tooling, base plates, and high-end fixture applications.Excellent Heat Resistance
Maintains shape and performance even under high-temperature conditions. Withstands up to 340°C in reflow ovens or thermal environments without warping.400-Grit Polished Surface
Achieves a mirror-like, finely polished finish (up to 400 mesh) that is ready for direct anodizing without additional surface preparation.

Super Flat Aluminum Plate Applications
1. High-precision equipment substrate
Used for CNC processing platforms, laser cutting machines, semiconductor equipment, 3C electronic assembly platforms, etc.
The board surface must not be warped or deformed to ensure machining accuracy and assembly accuracy.
2. Optical and LCD panel industries
LCD/LED backlight module fixtures, inspection platforms
A super-flat surface is required to prevent the display panel from warping or damage.
3. Structural parts of electronic products
Mobile phones, notebook computer middle frames, thermal conductive substrates, shells
Aluminum plates must have good anodized surfaces and dimensional stability.
4. SMT high-temperature furnace carrier
Undergo repeated 300°C+ high temperature thermal cycles, the board surface must still be kept from warping.
5. High-end mold templates
Suitable for mold substrates and mold bases, with extremely high requirements for thickness and flatness
