Product Description

Alloy Overview

Alloy 48 (UNS designation K94800, W.Nr. 1.3922 / FeNi48) is a binary iron-nickel controlled-expansion alloy composed of approximately 48% nickel with the balance iron. It is marketed under several trade names including NILO 48, Pernifer 48, Invar 48, and Glass Sealing 48.

The alloy is engineered to closely match the coefficient of thermal expansion (CTE) of soft lead and soda-lime glasses, as well as specific ceramic materials up to approximately 500 C (930 F). Common industrial applications include soft-glass-to-metal hermetic seals, thermostatic bi-metal strip components, electronic vacuum tubes, specialized lighting electrodes, and cathode-ray tube shadow masks.

Its notable resistivity, excellent corrosion resistance, and controlled magnetic properties allow for usage in demanding environments where stability and reliability are key factors.


Customized Supply Options

Alloy48 Scrap is available as mixed, unsorted lots with tailored lengths, thicknesses, and packaging options-including loose or metal scrap bundles. Dealers, exporters, and manufacturers across India supply this alloy, providing flexibility for different operational requirements and bulk ordering needs.

FAQ's of Alloy48 Scrap NILO 48 Scrap Pernifer 48 Scrap:


Q: How is Alloy48 Scrap (NILO 48/Pernifer 48) typically used in industry?

A: Alloy48 Scrap is primarily used for recycling, melting, and alloy recovery. Its controlled magnetic properties and low expansion make it ideal for manufacturing nuclear and electronic components that demand precise material characteristics.

Q: What is the typical process for recycling Alloy48 Scrap?

A: The recycling process involves collecting and sorting the scrap, followed by melting and purifying it to recover the original alloy. This process helps retain the nickel-iron composition, conforming to ASTM F30/UNS K94800 standards for high-quality re-use.

Q: When should industries choose NILO 48 Scrap over other types of metal scrap?

A: Industries should select NILO 48 Scrap when low expansion, reliable resistivity, and controlled magnetic properties are critical. It's most beneficial in applications involving electronic or nuclear component production where precise alloy properties are essential.

Q: Where can Alloy48 Scrap be sourced in India?

A: This scrap can be acquired from various dealers, exporters, manufacturers, and suppliers operating throughout India, many of whom offer custom packaging (loose or bundled) and bulk lot options to fit industrial supply chains.

Q: What are the main benefits of recycling Pernifer 48 Scrap?

A: Recycling Pernifer 48 Scrap not only conserves valuable nickel and iron resources but also supports sustainable industry practices while ensuring a steady supply of high-purity, specification-compliant alloy for demanding applications.

Q: How does the corrosion resistance of Alloy48 Scrap benefit end-users?

A: Its excellent corrosion resistance ensures long-term stability and durability, making it suitable for use in normal environments where protection against rust and degradation is significant for component lifespan.

Q: What is the typical packaging for this scrap material?

A: Alloy48 Scrap is generally available either loose or in metal scrap bundles, depending on customer preference and operational requirements, simplifying transport, storage, and handling for bulk industrial users.
