Product Description Ni29Co18/ UNS K94610 (4J29) Kovar Expansion Precision Alloy Strip PricePrecision alloy 4J29 is a Fe-Ni-Co alloy, and it has similar liner expansion coefficient with hard borosilicate glass under the temperature of 20-450oC, with high Curie point and good low-temperature stability.4J29 has tense oxide film and can be well wetted by the glass. It is suitable for mercury discharge instrument because it doesn't react with mercury. 4J29 alloy is the main material of sealing parts in electric vacuum devices.Grade4j29,4j36,4j42,4j43,4j44,4j47,4j50etcSharpwire, bar/rod, strip, sheet, tubeStandardGB/T15018,YB/T5231-2005,YB/T5241-2005,YB/T5235-2005etc.Basic performanceIt is divided into low-expansion alloy and fixed-expansion alloy, the latter is also known as sealing alloy.Expansion alloy besides has the specific thermal expansion coefficient, according to the different USES also requires a good sealing property, weldability and corrosion resistance, machinability and cutting, and in the use of expansion characteristics caused by the temperature range there is no obvious change of phase transformation, its product is commonly bar, sheet, strip, wire and tube and so on. Expansion alloy applications It is widely used in glass, metal and ceramic sealing in avionics and instruments, electric vacuum industry and other electronic devices, electric light source and other fields.GradeCMnSPSiCrNiFe4J29≤ 0.03≤ 0.5≤ 0.02≤ 0.02≤ 0.3≤ 0.228.5-29.5%rest Size RangeWire0.05-7.5mmRod / bar8.0-200mmStrip(0.5-2.5)*(5-180)mmTubecustom madePlatecustom madeQ1: Do you accept the trial order ?A1: Yes,if we have the exactly size in stock.we can delivery even 1 piece/meter .Q2: Can I have free sample before making orders?A2: Yes,we can supply free sample as requirement,but buyer needs to pay the freight charges ,the freight fee will return to buyer after making order.Q3: How do you control the quality ?A3: MTC and PMI will be sent before shipment,any 3rd party inspection if need .Q4: How about your delivery time ?A4: Generally delivery time is 15 working days .Q5: How can I quickly get the price list ?A5: Directly click "chat now" or send us email with detail specifications,you will get the official price list in 1 hour .
