Invar 52 Bar Annealed FAQs

Q1: What are the key material properties of Invar 52 Bar Annealed?

A1: Invar 52 Bar Annealed is an iron-nickel alloy composed of approximately 52% nickel and 48% iron, valued for its very low coefficient of thermal expansion. It exhibits excellent dimensional stability and maintains its mechanical integrity over a broad temperature range. Typical properties include high softening resistance, moderate tensile strength, and superior metallurgical homogeneity. This makes it well-suited for applications requiring tight tolerance control and minimal thermal distortion.

Q2: How can Invar 52 Bar Annealed be processed or fabricated?

A2: Invar 52 Bar Annealed can be machined using conventional methods, though slow feed rates and sharp tooling are recommended due to its tendency toward work hardening. It can be cold or hot rolled, drawn, and formed with appropriate temperature control to prevent stress buildup. Annealing is performed at elevated temperatures followed by controlled cooling to relieve stresses, maintain dimensional accuracy, and retain the alloy’s low expansion properties.

Q3: Which quality standards and certifications apply to Invar 52 Bar Annealed?

A3: Invar 52 Bar Annealed typically meets ASTM F30 specifications, ensuring consistent material composition and mechanical performance.
