Overview: The document describes a 5052 super high precision aluminum alloy plate designed for precision machining. It aims to meet customer needs for reduced residual stress, improved surface quality, and superior accuracy in thickness and surface flatness, ultimately helping to reduce costs.

Features: The alloy plate includes marking to show the direction of rolling. It boasts improved manufacturing processes for increased flatness, superior rolling technology achieving approximately 1/10 the JIS standard accuracy for thickness, and a distinctive heat treatment process that significantly reduces internal residual stress. Each plate is carefully inspected to ensure high-quality surfaces on both sides.

Applications: The alloy plate is suitable for semiconductor manufacturing equipment, LCD manufacturing equipment, solar panel manufacturing equipment, robots, medical equipment, office automation equipment, optical equipment, various molds, and tools.

Residual Stress: The document provides a distribution of internal stress over the direction of thickness, comparing standard 5052 with the super high precision version.

Quality/Refining/Composition: The composition of the alloy is detailed in weight percentages, with specific limits for elements like Si, Fe, Cu, Mn, Mg, Cr, and Zn, with the remainder being aluminum.

Thickness Accuracy: The document outlines the tolerance and thickness variation per original plate, with specific reference to JIS tolerance standards.

Surface Flatness: The document emphasizes the importance of surface flatness in the manufacturing process.

Mechanical Properties: Typical values for tensile strength, yield strength, and elongation are provided for various thicknesses.

Product Size: The document specifies the available thickness, width, and length of the product.
