Strain gauge - Import export

Evanohm® R is a unique resistance alloy with high electrical resistivity and very low temperature coefficient of resistivity (TCR). The alloy is produced by melting and conditioning practices which result in a low level of pinholes at ultra-thin thicknesses. This combination of attributes with inherent corrosion resistance makes it suitable for a variety of strain gauge, foil heaters and airbag igniters. The alloy is supplied with 90% cold reduction which has a positive TCR of about 70 PPM/ºC. A stabilizing heat treatment (approximately 475ºC) during manufacture of finished parts adjusts the TCR to a desired value. The heat treatment virtually eliminates any drift tendency of the resistivity. A heat-treat curve for each melt is developed at Hamilton and is made available as a guide in regulating TCR. Sizes Evanohm® R is available from Hamilton Precision Metals as foil and strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) and in widths up to 12.0”
