Aremcolox 502-1550-LD Low Expansion Ceramic Now Available
Valley Cottage, NY - March 7, 2008
SUMMARY
Aremcolox(TM) 502-1550-LD, a new low expansion, zirconia phosphate machinable ceramic
manufactured by Aremco Products Inc., is now used to produce high temperature fixtures and insulators used in brazing, heat treating, optical and semiconductor applications to 1550 oC.
FEATURES
Aremcolox(TM) 502-1550-LD is a zirconia phosphate based machinable ceramic used for producing specialized brazing fixtures, induction liners, wafer chucks, optical stands, and combustion nozzles for applications to 1550°C.
Aremcolox(TM) 502-1550-LD is a highly unusual composition due to its low coefficient of thermal expansion (CTE) of 0.5 ppm/°F. This feature sets it apart from conventional ceramics such as alumina and zirconia that demonstrate a CTE as high as 4.0 ppm/oF. A low CTE ensures that as a part experiences thermal shock, the mechanical stress caused by its expansion and contraction does not cause the part to crack.
Aremcolox(TM) 502-1550-LD is a 60-70% dense composition that exhibits good mechanical
strength and electrical and thermal insulation, and a compressive strength of 25 Kpsi, dielectric strength of 80 volts/mil, and thermal conductivity of 5.3 Btu-in/hr-ft²-°F. 502-1550-LD is completely inert, will not outgas in ultra high vacuum, and does not react with most molten metals, salts and acids.
Aremcolox(TM) 502-1550-LD is typically machined using carbide or diamond tooling and no post firing is required. Aremcoloxtm 502-1550-LD is available in rods from ½" to 2" diameter and plates from ¼" to 1" thick. Custom sizes and parts are also produced to print.
