Product Description Nickel Alloy UNS KOVAR 4J29 tube / pipe with high qualityRelative Grade:29H Kovar Nilo K KV-1 Dilver P0 Vacon 1229H-B Rodar Telcaseal KV-2 Dilver P1 Silvar 48Specification: Sheet/Plate, Bar/Rod/Wire/Coil,Capillary/Pipe/Tube products description 4J29 bar General DescriptionKovar is a nominal 29%Ni-17%Co-54%Fe alloy that is a well-known glass-sealing alloy suitable for sealing to hard glasses. Kovar has a nominal expansion coefficient of approximately 5 ppm/°C and inflection temperature of ~450 °C (840 °F).Kovar (ASTM F15) has been used for making hermetic seals with the harder Pyrex glasses and ceramic materials. This alloy has found wide application in power tubes, microwave tubes, transistors, and diodes. In integrated circuits, it has been used for the flat pack and the dual-in-line package.Chemical Composition GradeC%P%S%Mn%Si%Cu%Cr%Mo%Ni%Co%Fe%KovarMax 0.03Max 0.020Max 0.020Max 0.50Max 0.30Max 0.20Max 0.20Max 0.2028.5-29.516.8-17.8Bal.SpecificationsGradeUNSWerkstoff Nr.ASTMKovarK946101.3981F15 Physical PropertiesGradeDensityMelting PointKovar8.17 g/cm31449°CMechanical PropertiesGradeTensile Strength N/mm2Soft1/4 Hard1/2 Hard3/4 HardFull HardKovar Strip<570520-630590-700600-770>700Kovar Wire<585585-725655-795725-860>860Coefficient of ExpansionAlloyLinear Coefficient of Thermal Expansion ā,10-6/oC20-200oC20-300oC20-400oC20-450oC20-500oC20-600oC20-700oC20-800oCKovar5.95.35.15.36.27.89.210.2Size Range: *Sheet---Thickness 0.1mm~40.0mm, width:≤300mm,Condition: cold rolled(hot), bright, bright annealed *Round Wire---Dia 0.1mm~Dia 5.0mm,Condition: cold drawn, bright, bright annealed *Flat Wire---Dia 0.5mm~Dia 5.0mm,length:≤1000mm,Condition:flat rolled, bright annealed *Bar---Dia 5.0mm~Dia 8.0mm,length:≤2000mm,Condition:cold drawn,bright, bright annealed Dia 8.0mm~Dia 32.0mm,length:≤2500mm,Condition:hot rolled,bright, bright annealed Dia 32.0mm~Dia 180.0mm,length:≤1300mm,Condition:hot forging,peeled, turned, hot treated *Capillary---OD 8.0mm~1.0mm,ID 0.1mm~8.0mm,length:≤2500mm,Condition: cold drawn, bright, bright annealed *Pipe---OD 120mm~8.0mm,ID 8.0mm~129mm,length:≤4000mm,Condition: cold drawn, bright, bright annealed
