관련 제품 특징:
  • OhmAlloy-4J36 is a nickel-iron alloy with an exceptionally low coefficient of thermal expansion.
  • Ideal for applications requiring high dimensional stability like precision instruments and seismic creep gauges.
  • Suitable for oxyacetylene welding, electric arc welding, and other welding methods.
  • Preferably welded using Argon arc welding with filler metals containing 0.5% to 1.5% titanium to reduce porosity and cracks.
  • Available in various forms including wire, strip, foil, and bar with customizable dimensions.
  • Features a density of 8.1 g/cm3 and electrical resistivity of 0.78 Ωmm2/m at 20℃.
  • Can be annealed for stress relief or to eliminate hardening from cold-rolled processes.
  • Surface treatments include sandblasting, polishing, or pickling with 25% hydrochloric acid at 70℃.
FAQ:
  • What is the minimum order quantity for OhmAlloy-4J36?
    If the size is in stock, any quantity can be provided. For custom sizes, spool wire requires 2-3kg and coil wire requires 25kg.
  • How can I pay for a small sample order?
    Payment can be made via wire transfer for sample amounts.
  • Do you provide free samples of OhmAlloy-4J36?
    Free samples are available for several meters if the size is in stock, but the customer must cover international express costs.
  • What are the payment terms for bulk orders?
    Payment terms include LC and T/T, depending on delivery and total amount. Details can be discussed based on specific requirements.
