Title:
HYDROGEN PERMEABLE COPPER ALLOY, HYDROGEN PERMEATION MEMBRANE AND STEAM REFORMER
Document Type and Number:
Japanese Patent JP2013209729
Kind Code:
A
Abstract:

To provide a Cu-Pd alloy excellent in hydrogen permeability and strength.

A hydrogen permeable copper alloy is represented by compositional formula: PdaCubXc (X: at least one of Al, Ga and In, a: 43-49 atom%, b: 1-a-c, and c: 0.02-2 atom%), and has an average crystal particle size in a β phase of 4 μm or less when heat treatment at 300°C for 20 hours is performed.
