The structure of an alloy 29HK (Covar), belonging to group of metal alloys, includes iron (53%), cobalt (17%), nickel (29%). Covar is melted in electric furnaces, the necessary alloying additives are entered into an alloy in the form of ferroalloys. It is possible to reach an alloy pretsizionnost at exact control of structure even in the course of smelting.
Characteristics of an alloy Covar:
• density is 8350 kg/m3
• module of elasticity of 1,96*1011 pases (N/sq.m)
• strength 0,65 gp (65 kgfs/mm2)
• heat conductivity of 19 W · м−1 · к−1
• ferromagniten, temperature of curie is 420 °c
• temperature of melting is 1450 °c, specific electric resistance 0,5 mky
• coefficient of thermal expansion (4,5—5,2)·10−6 1° c in the range of 20 — 400 °c
Alloy advantages Covar:
• high degree of plasticity,
• resistance to corrosion,
• low indicator of expansion.
Alloy scope Covar:
• in electrical equipment,
• electrovacuum devices,
• as an insulator for chips in devices with the metalglass case,
• in radio devices with various types of glasses this alloy can be applied to vacuum soldering of details,
• components of the majority of modern glow lamps or daylight,
• conclusions of chips.
