Technical characteristics
Wide application of 29NK wire became possible because of its low cost and high manufacturability of the alloy. This alloy is very plastic and easy to roll and solder. The wire does not need any additional protective coating when used in a humid environment. The coefficient of thermal expansion is the same as that of glass. TKLR*1000000 in the temperature range from -70 to +420 ºC does not exceed 4.5-6.5 [1/ºC].
Application
It is used for parts of radioelectronic equipment, airtight connection with C49-1, C52-1, C48-1, C47-1 glasses;
Production
Smelted in electric furnaces, the necessary alloying components are introduced into the composition during the melting process in the form of ferroalloys. Precise control over composition is required at all stages of production to ensure the required quality.
