Seller: advancer53 (3,233) 100%, Location: Baldwinsville, New York, Ships to: Worldwide, Item: 301303384973 6.875" LONG SMALL DIAMETER HIGH PURITY SINGLE BORE ALUMINA CERAMIC TUBING STOCK REFRACTORY No.: 147You are buying ONE (1) only of a 6.875" Long Small Diameter High Purity Alumina Ceramic Tubes Tubing Stock. They are in mint condition being NOS (New Old Stock). They are made from 99% purity Aluminum Oxide (Al2O3) which of course is Alumina. Generally the balance of composition for this purity Alumina material is of Silicon Dioxide (SiO2) which is Silica.These tubes are fired to full density; and are therefore not porous. This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature. They may be used for a variety of electrical, mechanical, and thermal applications. They may be used as setter plates for firing parts in a kiln. The may be used for high temperature furnaces and as high temperature refractory turntables. They may also be used for jewelry or for applications requiring high wear or abrasion resistance. Your imagination is the only limiting factor in the spectrum of possible applications for this component. Be sure to view all photos as they are an integral component of the item description. The specifications for these components are as follows: Outside Diameter: Average Approximately 0.125" +/- 0.006" or (3.18 +/- 0.15 mm)Inside Diameter: Average Approximately 0.062” +/- 0.003" or (1.57 +/- 0.08 mm)Wall Thickness: Average Approximately 0.030” (0.75 mm)Length: Average Approximately 6.875” +/- 0.063" (174 mm) Please Note: These are precision technical ceramic components. There is no warp or camber on these items. They are straight and round. The thermal shock resistance is not very high so exercise rule of thumb caution. “The larger the piece of material the slower the rate of temperature increase should be applied to the piece.” Heat up slowly to avoid cracking in use. Specific Gravity or Density: 3.9 g/cm3Water Absorption or Porosity: 0%Fusion Temperature or Melting Temperature: 2000 °C or 3632 °FMaximum Working Temperature: 1500 °C or 2732 °FThermal Conductivity: 25 W/m* KSpecific Heat: 0.9 J/g*KExpansion Coefficient or CTE: 7.5 x 10 E -6 inches/°CElectrical Resistivity at 20 C: 10 E 14 Ohm*cmElectrical resistance at 600 C: 10 E 8 Ohm*cm Modulus of Elasticity: 44 x 10 E 6 p.s.i. or 350 GPa. These components were not specifically manufactured for an individual application; therefore be sure to check the dimensional descriptions carefully for your application. Future returns or requests for refunds, because of some "fit" issue or the like will not be honored.
