Inflection point 360°C. A nickel-iron-chromium controlled-expansion alloy containing 47% nickel. It is designed to have thermal-expansion characteristics that closely match those of the soft glasses of the lead or soda-lime type up to their annealing temperatures. The alloy is a particularly good match with L92 glass. Used for various glass-to-metal seals and for anode-cavity caps in television tubes. The standard product form is strip.
