Metal Diaphragm

The metal diaphragm is a circular membrane-shaped elastic sensitive element that will elastically deform when subjected to axial load or pressure. It is usually made by stamping a thin metal sheet into a corrugated shape. Metal diaphragms are widely used in food processing, pharmaceuticals, semiconductors, medical equipment, industrial machinery, consumer electronics, and other industries.

    Corrugated Metal Diaphragm

    The metal diaphragm is a circular membrane-shaped elastic sensitive element that will elastically deform when subjected to axial load or pressure. The metal diaphragm is usually made of high-quality metal materials, such as stainless steel, Inconel, titanium, or nickel alloy. These materials offer excellent mechanical properties, corrosion resistance, and durability, ensuring reliable performance in demanding environments.

    Metal diaphragms are widely used in food processing, pharmaceuticals, semiconductors, medical equipment, industrial machinery, consumer electronics, and other industries.

    There are three main types of metal diaphragms:  striped, dome-shaped, or flat; corrugated diaphragms are the most widely used, but corrugated diaphragms require matching molds for mass production. They have a large deformation capacity and a linear characteristic curve.

    We offer metal diaphragms in various materials and sizes, please consult us for more details.

    Metal Diaphragm Dimensions

    Drawing of the diaphragm
    D1: Outer diameter
    D: Effective diameter
    J: Corrugation center distance
    J1: Corrugated spacing
    d: Center plane diameter
    d1: Center hole diameter
    h: Corrugation height
    R: Ripple radius

    Corrugated diaphragms require professional mold production, which may require additional mold production costs (later mass production can gradually offset the mold production costs). Our existing molds can produce the following sizes.
