We at Navratna Metal Corporation put in a lot of efforts to devise sustainable high-quality products that are usable in different environments. We manufacture these products using top-notch raw materials and hence ensure their reliability and durability. Our Tantalum Sheets are hard, ductile and highly corrosion resistant products. These Tantalum Sheets are resistant to a lot many chemicals. Our Sheets made from Tantalum have a high melting point and can be formed into extremely thin protective oxide layers on high-quality capacitors. Our Tantalum Sheets are used in many industries such as laboratory equipment’s, super-alloy additives in nickel-alloys, substitutes for platinum and more. These Tantalum Sheets are used in applications where anti-corrosive properties are needed. Also, these sheets find usage in chemical processing and military applications.We take care of various aspects while developing our goods such as uniformity in thicknesses, constant surface finishing and consistent flatness all over the sheets. We produce our products maintaining international standards of quality and durability. Our products are known for their optimum usability in various conditions of use.
