Super Invar 32-5 Foil Thickness 0.005 inch FAQs

Q1: What are the key material properties of Super Invar 32-5 Foil Thickness 0.005 inch?

A1: Super Invar 32-5 foil is an iron-nickel-cobalt alloy specifically formulated to exhibit an exceptionally low coefficient of thermal expansion in the critical temperature range of approximately 20°C to 200°C. This 0.005-inch foil maintains consistent dimensional stability under thermal cycling, with typical expansion rates near 1–2 × 10⁻⁶/°C. It also displays good ductility, moderate tensile strength, and excellent magnetic permeability, making it suitable for high-precision instrumentation and metrology applications.

Q2: What processing methods are recommended to maintain the dimensional stability of a 0.005-inch Super Invar 32-5 foil?

A2: Processing should occur in controlled environments with careful attention to temperature and handling procedures. Common methods include cold rolling for thickness control and vacuum or inert-atmosphere annealing to relieve stress without oxidising the surface. Fabrication steps such as stamping, laser cutting, and precision machining should involve low heat generation. Post-processing stress relief at recommended temperatures helps maintain the foil's low-expansion behaviour and prevents distortion.

Q3: Which quality standards and certifications apply to Super Invar 32-5 Foil Thickness 0.005 inch?

A3: Typical specifications for Super Invar 32-5 foil come under standards such as ASTM F1684, which governs low-expansion alloys. Manufacturers often hold certifications including ISO 9001 or AS9100 to ensure consistent quality and traceability. Documentation typically includes chemical composition reports, mechanical property verifications, and dimensional inspections to confirm conformance.
