1. Manufacturing Process

Manufacturing Invar 36 foil with a thickness of 0.005 inch demands a combination of thermal control and precision rolling techniques. Specialized equipment is used to ensure the foil’s thickness remains uniform along its entire length, keeping its dimensional stability intact. During the rolling stage, carefully calibrated rollers gradually reduce the material to the desired thickness, preventing structural defects and preserving the alloy’s unique low coefficient of thermal expansion.

Strict attention is given to heat treatment procedures before and after the rolling phase. The foil is subjected to controlled annealing cycles designed to optimize its internal grain structure and minimise stresses accumulated during deformation. By following developed temperature profiles, fabricators maintain the foil’s dimensional stability while preserving the mechanical properties critical for advanced applications involving tight dimensional tolerances.

2. Quality Control Measures

Thorough inspections are conducted at multiple phases to verify that the 0.005-inch foil thickness meets strict dimensional requirements. Non-destructive testing methods, such as eddy current and ultrasonic evaluations, reveal any hidden flaws or inconsistencies in internal structure without compromising the integrity of the foil. This level of scrutiny ensures that each roll of finished Invar 36 foil aligns precisely with project specifications and end-use demands.

Continuous monitoring also extends to the chemical composition of the Invar 36 alloy. Samples are regularly analysed using spectroscopic equipment to confirm the balance of iron and nickel is maintained within allowable limits. Any batch drifting beyond these thresholds is immediately flagged, preventing potential variations in performance and ensuring reliable material behaviour over a broad temperature range.
