Document Type and Number:

WIPO Patent Application WO/2019/116755

Kind Code:

A1

Abstract:

Provided are: a pellicle frame body for a flat panel display (FPD) having high dimensional accuracy and flatness, the pellicle frame body being capable of maintaining the rigidity required for a pellicle for a large flat panel display (FPD) even if the cross-sectional area of the frame is reduced, and enlarging the inside dimension of the frame body by reducing the cross-sectional area; and an efficient manufacturing method therefor. The present invention provides a pellicle frame body for a flat panel display (FPD), the pellicle frame body being characterized by being composed of an extruded material of an aluminum alloy powder sintered body comprising 20-40 mass% of Si, 0.2-1.2 mass% of Mg, 2 mass% or less of Cu, 2 mass% or less of Fe, 0.4 mass% or less of Cr, and the balance comprising Al and inevitable impurities.
