HPM® 80/20 A Resistance Alloy

HPM® 80/20 A is a resistance alloy used in electric heating applications. It is recommended for use in dry air applications up to 2150°F with good hot strength. Such as, flexible metal foil heaters and airbag igniters. The alloy forms rather well and has good welding characteristic. Caution should be used to avoid extended exposure to elevated temperature in marginally oxidizing or partially reducing atmospheres as it would be susceptible to “green rot” corrosion, carburization and sulfurization. Available Sizes: HPM® 80/20 A is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and width up to 12” (304.8 mm). The material conforms to ASTM B-344. Foil product may be supplied in thickness to 0.0001” (0.00254 mm) in width up to 4.0” (101.6 mm).
