Independently developed, our new formula products address challenges such as sputtering pot issues and corrosion of nickel and copper. Through advanced formulation technology, components are optimized to ensure excellent chemical stability and stable resistivity. These products also offer exceptional oxidation resistance, effectively combating corrosion from aluminum, nickel, copper, and gold. With a maximum operating temperature of 1800°C, they are well-suited for demanding applications.
