A customer that makes ultra low friction pneumatic pistons and cylinder motion dampers needed a mounting cap that would expand at the same rate as the Pyrex cylinder the cap is bonded to. The part also required a thread to be machined on the O.D. of the stand off. Perry Tool and Research suggested using a powdered metal version of Invar 36, which is a nickel steel alloy notable for its uniquely low coefficient of thermal expansion. This material expands at a similar rate as glass; thus ensuring... (read more)Browse Powder Metal Services Datasheets for Perry Tool & Research, Inc. -

tungsten metal is widely utilized as a heating element material in industrial furnaces which have inert or a reducing hydrogen atmosphere. Its resistance to thermal shock and corrosion provide advantages in the production of evaporation sources in vacuum metallizing operations. Because of its low coefficient of thermal expansion, similar to that of silicon, tungsten is often used to produce heat sinks for silicon diode chips. In such a construction, the silicon can be safely bonded to the tungsten... (read more)Browse Tungsten and Tungsten Alloys Datasheets for Elmet Technologies, Inc.
