Molybdenum Washer

Molybdenum washers are precision-machined refractory metal components designed for high-temperature, high-vacuum, and corrosive environments. Thanks to molybdenum’s high melting point (2620°C), excellent mechanical strength, and low vapor pressure, these washers are widely used in demanding industrial applications where conventional steel or alloy washers fail.

Our molybdenum washers are manufactured from high-purity molybdenum material and can be supplied in both standard and fully customized dimensions to meet specific equipment and assembly requirements.
