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).

Copper alloys exhibit very high electrical and thermal conductivities, offering twice the conductivity of aluminum and thirty times the conductivity of stainless steel. Other advantageous characteristics include outstanding strength (notably copper beryllium alloys) and corrosion resistance as well as antimicrobial properties. Copper is most commonly used in electrical and electronic applications.

Copper 102 is an oxygen-free copper with extremely high electrical conductivity and good formability. These characteristics make it particularly useful for electrical connectors. Copper 102 can be deep-drawn from the annealed temper.It is corrosion resistant in normal atmosphere and water. A thin adherent oxide film forms at elevated temperatures which prevents particle contamination and enhances glass to metal seals. The Copper 102 can be readily soldered and brazed. The absence of oxygen makes welds free of inclusions.
