Influence factor for the high-permeability alloy are studied in this paper. Employing reasonable control process for heat treatment technology, the magnetic properties of materials were improved.

Flaky morphology of magnetic alloy particle material can raise its natural resonance frequency because of strong shape anisotropy, which is advantageous to acquiring high microwave permeability.

The hydrogen permeability of the composite membrane is very high and the cost of the composite membrane is low because the palladium silver alloy film is very thin.
