Al2o3 Ceramic Plate 99.99% Alumina Ceramic parts

The high temperature ceramic have best heat properties for ceramic component parts. Ceramic materials for ceramic components generally have high melting point (mostly above 1800℃) and excellent chemical stability and best insulation at high temperature.Ceramic thermal conductivity for ceramic parts is lower than metal materials, and a good thermal insulation material.At the same time, the linear expansion coefficient of ceramics is lower than that of metals. When the temperature changes, ceramics component parts have good dimensional stability. Features Alumina ceramic Screw advantages: 1. High purity:Good resistance of high temperature and abrasive. 2. Tight Tolerance. we can machine the alumina seal ring to make tight tolerance, good surface roughness and flatness. 3. Various processing methods, casting, preesing, grinding etc. 4. Competitive prices 5. Inspection: each single alumina ring will be checked before shipping. 6. Low transportation cost : We have long time cooperated shipping agency, which can provide very low prices. If you need Alumina ceramic Screw, please let me know!
