Niobium Sheets

Refractory metals have a high melting point, low vapor pressure, low coefficient of thermal expansion, excellent high temperature strength and creep resistance. Through alloying, their processing properties and high temperature performances are further improved, and the service life of products is extended. Therefore, tungsten, molybdenum, tantalum and niobium metals are widely used in all kinds of high temperature furnaces as structural materials, heating body and insulation laye
