Technical characteristics
Alloy with high quality, precision; with corrosion resistance in some acidic and corrosive environments. Melting point is 1450 °C. the Coefficient of thermal expansion the same as that of glass. CTE*1000000 in the temperature range from -70 to +420 ° C does not exceed 4.5−6.5 [1/ºC]. Used for parts of electronic equipment, airtight connection from Windows С49−1, C52−1, C48−1, С47−1;
Production
Is smelted in electric furnaces, the necessary alloying components are introduced into the composition during melting in the form of ferroalloys. At all stages of production requires a precise control of the composition to achieve the desired qualities.
