Super Invar 32-5 Rod Annealed FAQs
Q1: What are the key material properties of Super Invar 32-5 Rod Annealed?
A1: Super Invar 32-5 Rod Annealed is an iron-nickel-cobalt alloy with approximately 32% nickel and 5% cobalt, known for its extremely low coefficient of thermal expansion. This unique composition ensures minimal dimensional changes across a broad temperature range, making it ideal for precision instruments and tooling. Its annealed condition provides improved ductility and machinability, while maintaining excellent stability. Additionally, it offers reliable thermal conductivity and moderate tensile strength.
Q2: How can this Super Invar 32-5 Rod Annealed product be processed or fabricated?
A2: Super Invar 32-5 Rod Annealed can be machined using standard techniques, although slow cutting speeds and suitable coolants are recommended due to its tendency to work-harden. It can also be formed and welded, but preheating and post-weld stress relieving may be necessary to minimise cracking. Heat treatments can fine-tune mechanical properties, and close process monitoring ensures dimensional stability. Careful handling reduces the risk of distortion.
Q3: Which quality standards and certifications apply to Super Invar 32-5 Rod Annealed?
A3: Super Invar 32-5 Rod Annealed typically complies with AMS I-23011 or ASTM F1684 specifications to ensure consistent composition and performance. Manufacturers often follow ISO 9001 quality management systems to maintain strict production controls and traceability. Additional certifications, such as AS9100 for aerospace applications, may apply depending on end-use requirements. Inspection procedures often include dimensional checks, chemical composition analysis, and nondestructive testing to confirm overall integrity and compliance with industry standards.
