Title:
HYDROGEN PERMEABLE COPPER ALLOY, HYDROGEN PERMEABLE FILM, AND STEAM REFORMER
Document Type and Number:
Japanese Patent JP2012201974
Kind Code:
A
Abstract:

To provide a Cu-Pd alloy excellent in hydrogen permeability in high-temperature and high-pressure conditions, strength, and stress relaxation resistance.

The hydrogen permeable copper alloy is represented by composition formula: PdaCubXc (X: at least one among Al, Ga and In; a: 41-50 at%; b: 1-a-c, c: 0.2-2 at%). In the hydrogen permeable copper alloy, the ratio of β-phase at 600°C is 5% or higher.
