Super Invar 32-5 Rod 1/2 inch FAQs

Q1: What are the key material properties of Super Invar 32-5 Rod 1/2 inch?

A1: Super Invar 32-5 is an iron-nickel-cobalt alloy typically containing about 32% nickel, 5% cobalt, and the remainder iron. The primary advantage is its exceptionally low coefficient of thermal expansion—often around 0.6 x 10^-6 /°C in the 20–100°C range—resulting in superior dimensional stability. The material also exhibits good mechanical strength, moderate hardness, and retains ferromagnetic properties, making it ideal for precision optical and metrology applications.

Q2: How is Super Invar 32-5 Rod 1/2 inch processed or fabricated for industrial use?

A2: Super Invar 32-5 Rod 1/2 inch is commonly machined using carbide or high-speed steel tools with coolants to minimise heat buildup. Grinding, turning, and drilling operations require moderate speeds to avoid work hardening. Post-fabrication stress relief annealing at around 800–900°C can improve dimensional stability. Welding is possible but demands controlled preheat and post-weld treatments to retain low thermal expansion properties and avoid excessive distortion.

Q3: Which quality standards and certifications apply to Super Invar 32-5 Rod 1/2 inch?

A3: Super Invar 32-5 Rod 1/2 inch often meets specifications such as ASTM F1684 or other internationally recognised standards for low-expansion alloys. Additional certifications may include ASME and ISO 9001 quality management qualifications for dimensional control and traceability. Suppliers typically provide material test reports (MTRs) verifying chemical composition, mechanical properties, and grain structure. Compliance with these standards ensures reliability, repeatability, and adherence to stringent industry requirements.
