Our Values

At Top Seiko, we pride ourselves in offering sophisticated molybdenum machining solutions and molybdenum products. Quality is the fundamental aspect of our organization and we take it very seriously. Right from start to finish, we ensure we abide by the quality guidelines and deliver our valuable customers high-quality products and materials. With our state of the art tools and equipment, we provide our customers with unmatched quality and capability at relatively low prices. Since we handle large volumes of molybdenum products, we have molybdenum in stock at all time, therefore, our customers can enjoy short delivery times, too.

Properties of Molybdenum

Molybdenum is a refractory metal that has a high melting point(2,623°C), high thermal conductivity but low thermal expansion compared with other metals. Molybdenum exhibits excellent resistance to corrosion from an inert gas, molten metals, and glasses as well as oxide ceramics even at very high temperatures. Knowing the best machining conditions of Molybdenum from years of experience, Top Seiko can machine Molybdenum with full automation that will cut down the price of our machined products significantly.

Contact us for your custom molybdenum fabrication parts. We'll be more than happy to support you on your next project.

You can see more detail of the property, application, and processing sample products on our website.
