Alloy 42 is a nickel-iron controlled expansion alloy with approximately 41% nickel balance iron, specifically engineered for glass-to-metal and ceramic-to-metal sealing applications in electronics and semiconductor packaging. It offers a matched thermal expansion coefficient ideal for hermetic seals in components such as transistor headers, diode bases, and vacuum tube envelopes. Widely sourced from producers in the US, Japan, and Germany, FeNi42 is available in strip, wire, and rod forms under ASTM F30 and related standards, making it a critical material in high-reliability electronic manufacturing. Pricing varies by form and purity, with strip commanding a premium over ingot or rod.
