Materials for Bellows [TOKUSHU KINZOKU EXCEL CO., LTD.]
TOKKIN 350, HC-22, HC-276, Alloy 625, SUS316L, SUS304L
Wide variety of metal materials for bellows! Please choose according to your specifications and purpose.
There are several types of bellows, such as welded bellows and molded bellows, depending on the manufacturing method. Bellows are used for pressure sensing and sealing because they can flexibly expand, contract, and bend while maintaining a tight seal for gases and liquids. Metal bellows have superior strength, corrosion resistance, and heat resistance, and are widely used in vacuum equipment for semiconductor manufacturing equipment, as well as in the aerospace and medical fields. Our company offers the following materials for bellows: TOKKIN 350, HC-22, HC-276, Alloy 625, SUS316L, SUS304L *For a detailed list of properties and more information, please refer to the related links or feel free to contact us.
