Material and Component
A5052P-H112
Aluminum Alloy Plate for Precision Machining
（Unit：Wt/%）
Featuring moderate strength, 5052 plate is an aluminum alloy plate of 5000 series with excellent corrosion resistance,
formability and weldability.
ALJADE made a debut as the new standard of 5052 plate by improving significant surface flatness
and reducing the residual stress compared to our conventional 5052 plate.

Reference
※Compared to our conventional product
The flatness of 5052 plate is significantly improved. 1.2mm/M → 0.6mm/M※
The original heat treatment technology reduces residual stress inside the plate approximately by half.※
