[QUOTE="BruceQuality, post: 17684, member: 618"] This is the one we use for NP and it has a similar CTE. Pisces Plus Nickel-Chromium ceramic alloy. Predominantly base alloy with ideal mechanical and physical properties for conventional feldspar ceramics. Advantages Excellent melting and flow properties Light oxide Excellent high temperature strength Works with conventional feldspar ceramics Certified biocompatibility Indications Single crowns Telescope and conus crowns Posts Short and long span bridges Partial dentures Composition Ni 61.5 Cr 22.0 W 11.2 Si 2.6 Al 2.3 Other metals< 1.0 Technical data Color white Density (g/cm³) 8.4 Melting range (ºC) 1255-1330 CTE 25 - 500 ºC 14.1 CTE 20 - 600 ºC 14.4 Elongation (%) 10.0 Vickers hardness 280 0.2% proof stress (MPa) 600 [/QUOTE]
