Tantalum foil and tantalum strip applications
Tantalum foil can be used as a vacuum blast furnace for heating elements, thermal insulation components and loading containers. In the chemical industry, tantalum foil is used as boilers, heaters, coolers, various appliances, etc. It is widely used in the aerospace and medical device fields. Tantalum foil is also used in foil capacitors. For more than 10 years, Hoau has been a leading supplier of rare metals such as tantalum, niobium and its alloys. Relying on China’s abundant non-ferrous metal mine resources, we use exquisite metal processing technology to meet the needs of customers in the fields of chemical industry, optoelectronics, aviation and other fields for non-ferrous metal materials.
