Product NameAlloy Strip Expansion Alloy 4J42 42H Glass Sealing 42 Nilo42 N42 FeNi42 K94100 Alloy 42
Product Description

Expansion alloy having a specific coefficient of thermal expansion, but also according to different uses require good sealing properties, weldability, corrosion resistance, workability and ease of machinability, and within the temperature range is not allowed to cause expansion characteristics significant changes in the phase transition. Expansion alloys in the manufacturing process must be accurate control of chemical composition of the alloy, and its products are generally rod, sheet, strip, wire and tube.
