Product FAQ
Q: What is the difference between Invar and Kovar wire?
A: Invar (4J36/4J32) offers the lowest thermal expansion for dimensional stability, while Kovar (4J29) provides controlled expansion perfect for glass-to-metal sealing applications.
Q: What diameters are available for your low thermal expansion alloy wire?
A: Standard range is 0.5mm to 7.5mm; fully customizable to your exact specifications.
Q: Can DLX provide samples of super invar wire or Kovar wire?
A: Yes, free samples are available (customer covers shipping). Lead time for samples is 7 days.
Q: Are your precision alloy wires suitable for global export?
A: Absolutely. We offer worldwide shipping with flexible terms (FOB, CIF, DDP) and full documentation.
Q: What certifications do your glass to metal sealing alloy wires hold?
A: ISO9001 and SGS certified with complete test reports for every batch.
Q: How do I order custom Invar Kovar grades wire?
A: Contact our team directly — we provide OEM/ODM services with rapid prototyping for precision expansion alloy wire needs.
