Super Invar 32-5 Sheets and Plates, including UNS K93500 variants, are widely used in industries requiring low thermal expansion. These sheets and plates come in various types such as hot rolled, cold rolled, shim sheets, perforated sheets, and chequered plates. The material is specifically engineered for high dimensional stability under changing temperatures, making it suitable for precision equipment.
Super Invar 32-5 is carefully chosen for its exceptional physical and functional properties. The grade typically contains a controlled composition of iron, nickel, cobalt, and trace elements. It is sourced from trusted suppliers and tested to ensure consistency, purity, and ability to perform in challenging environments, such as under extreme temperature and pressure.
The production process involves expert supervision at every stage—material selection, cutting, forming, and finishing. Post-production, the sheets and plates undergo rigorous quality checks, including thermal expansion tests and mechanical strength evaluations. This ensures the final products maintain stability between 67°F to 203°F and deliver reliable results in high-precision applications.
These sheets and plates are used in industries like metrology, scientific instrumentation, optics, and laser technologies. Super Invar 32-5 is especially suited for environments where compatibility with low expansion materials like glass or quartz is critical. Its minimal expansion coefficient makes it a go-to material for components that require long-term dimensional accuracy.
Super Invar 32-5 Sheets and Plates are available in a variety of specifications and sizes, including cut-to-size formats. The products are supplied across India, particularly in industrial hubs like Mumbai, and are readily available for both small-scale needs and bulk industrial orders.
