Since Pd was for the longest time rather stable in price, it was seen as a substitute for the more expensive gold. This was followed by a steep increase in the Pd price, which caused a significant reduction in its use in electrical contacts. Today (2011) the Pd price again is lower than that of gold.
Alloys of Pt with Ru, Ir, Ni and W were widely used in electromechanical components in the telecommunication industry and in heavy duty automotive breaker points (<xr id="tab:Physical Properties of platinum metalsPhysikalische Eigenschaften von Platin-Metallen und deren Legierungen/>). <figtable id="tab:Physikalische Eigenschaften von Platin-Metallen und deren Legierungen"><caption>'''<!--Table 2.7:-->Physikalische Eigenschaften von Platin-Metallen und deren Legierungen'''</caption> {| class="twocolortable" style="text-align: left; font-size: 12px"|-!Material!Platin/Palladium<br/>Content<br/>[wt-%]!Dichte[g/cm<sup>3</sup>]!Schmelzpunkt oder<br/>Schmelzbereich<br/>[°C]!Elekrische<br/>Widerstandskraft[µΩ*cm]!Elektrische<br/>Leitfähigkeit<br/>[MS/m]!Thermische<br/>Leitfähigkeit<br/>[W/m*K]!Temperaturkoeffizient des<br/>elektrischen Widerstands<br/>[10<sup>3</sup>/K]!Elastizitätsmodul<br/>[Gpa]|-|Pt (99,95)| >99,95|21,5|1772|10,6|9,5|72|3,9|173|-|PtIr5|95|21,5|1774 - 1776|22,2|4,5|42||190|-|PtIr10|90|21,6|1780 - 1785|17,9|5,6|29|2,0|220|-(Tab|PtRu10|90|20,6|ca. 1800|33,3|3,0||0,83|235|-|PtNi6|92|19,2.|1670 - 1710|30|3,3||1,5|180|-|PtW5|95|21,3|1830 - 1860|43,4|2,3||0,7|185|-|Pd (99,95)| >99,95|12,0|1554|10,8|9,3|72|3,8|124|-|PdCu15|85|11,3|1370 - 1400|38,5|2,6|17|0,49|175|-|PdCu40|60|10,5|1200 - 1230|33,3|3,0|38|0,28|175|-|PdNi5|95|11,8|1455 -1485|16,9|5,9||2,47|175|-|}</figtable>).
