توضیحات محصول

Expansion 4J50 Pipes Controlled Expansion Alloy

Expansion 4J50 Pipes are precision iron-nickel alloy pipes engineered for applications requiring controlled thermal expansion and reliable dimensional stability across varying temperature conditions. Containing approximately 50% nickel, these pipes provide a coefficient of thermal expansion that closely matches specific hard glasses and ceramic materials, making them highly suitable for glass-to-metal sealing assemblies and precision electronic components.

Unlike conventional stainless or nickel alloys that prioritize corrosion resistance or high-temperature strength, Expansion 4J50 Pipes are optimized for thermal compatibility and expansion control. Their stable metallurgical structure maintains dimensional accuracy during repeated heating and cooling cycles, which is critical in electronic packaging, vacuum systems, and instrumentation equipment.
