Technical characteristics
Wide application of wire 29NK was possible due to the low cost and high manufacturability of the alloy. This alloy is very plastic, easily rolling, soldering. The wire needs no additional protective coating when used in a wet environment. 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].
Application
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.
