<p>108.26.170.2: </p> <hr /> <div>{{Refimprove|date=December 2009}}<br /> <br /> '''Balco''' is a [[nickel]]-[[iron]] [[alloy]] with a [[thermal conductivity]] similar to nickel but twice the [[electrical resistance|resistivity]]. It is used for making low cost resistance temperature sensors. It consists of 70% nickel and 30% iron.<br /> <br /> Balco is Carpenter Technology Corporation's brand name for this alloy consisting of 70% nickel and 30% iron. It is also sold by Harrison as &quot;Hytemco&quot;. Its principal use is for [[resistance thermometers]] (resistance temperature detectors). These change their electrical resistances as a predictable function of temperature, making it useful as a thermometer with electrical output. Balco has a temperature coefficient of resistance of 0.00518 Ω/Ω/°C nearly as high as that of pure nickel (0.00672) but with much better linearity. It is also mechanically strong and fairly corrosion resistant. <br /> <br /> Pure platinum is preferred for the most precise resistance temperature detector elements in spite of its price and lower temperature coefficient (0.00385). This is because of its long-term stability and repeatability.&lt;ref&gt;{{Citation<br /> | title = Selecting a Temperature Sensor<br /> | url = http://www.minco.com/products/sensors.aspx?id=2590<br /> | accessdate = 2012-05-31<br /> | archive-url = https://web.archive.org/web/20120126135416/http://www.minco.com/products/sensors.aspx?id=2590<br /> | archive-date = 2012-01-26<br /> | url-status = dead<br /> }}&lt;/ref&gt;<br /> <br /> ==See also==<br /> <br /> * [[Thermometer]]<br /> <br /> ==References==<br /> {{reflist}}<br /> <br /> {{DEFAULTSORT:Balco Alloy}}<br /> [[Category:Nickel alloys]]<br /> <br /> <br /> {{Alloy-stub}}</div>
