You are buying a
LOT OF SIX (6) ALUMINUM OXIDE STANDARD WASHERS 0.865” O.D. x 0.260” I.D. x 0.055” THICK. They are
in excellent being NEw condition. They are made from 96% 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. This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractory ness or use temperature. These rings have a raised bearing face and an ID chamfer on the top side. They are slightly tapered. They may be used for a variety of electrical, mechanical, and thermal applications. They are great for firing sample in a high temperature kiln. The may be slumped at 3100 F (1700 C). The are great for both industrial or sculptural works of art. 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.
