Controlled Expansion Alloys
Nickel-Iron Alloys
Engineered to provide precise and predictable thermal expansion characteristics.
Controlled expansion alloys offer exceptional dimensional stability, reduced thermal stress and reliable performance across varying temperatures. Their carefully controlled thermal expansion characteristics make them ideal for glass-to-metal sealing, semiconductor packaging, aerospace components and other precision engineering applications where thermal compatibility is critical.
What Are Controlled Expansion Alloys?
Designed to deliver specific coefficients of thermal expansion (CTE), expansion properties of metals, glass, ceramics and composite materials are able to be matched. This makes them particularly valuable in applications where thermal cycling could otherwise lead to distortion, cracking or premature component failure.
