Alumina ceramic plates can withstand high temperature and maintain
high strength and hardness. Alumina plates also have superb
performances in electrical insulation, high chemical resistance and
low thermal expansion. We have various sizes of semi finished
shapes in stock and are able to conduct custom manufacturing for
all kinds of alumina components.
• Alumina plates are hard enough to become armor for personnel or
• The corrosion resistivity of alumina plates makes them a great
material for chemical industry.
• Used as a material for industrial furnaces due to its ability to
maintain its hardness at high temperatures.
• Used for making parts for CVD, ion implants, photolithography,
and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for
products such as injector tubes, gas nozzles and insulators.

*This chart just demonstrates the typical properties of common
alumina materials we use to produce our alumina parts. Please
notice that the property for customized alumina parts could vary
due to different process. Stanford Advanced Materials could provide
alumina products produced under your specified instruction, or do
the best to meet customers’ requirements.

Product features :
Applicable to make ceramic wrist watch, watch ctrap, bracelet, ring
and necklace etc. With the property of abrasion resistance,
invariant color, elegance and shining, ceramics are the ideal
decorative material for watch and jewelry industry. All the
ceramics can be customized.
1. High hardness.
2. High heat resistance : Alumina ceramic has excellent thermal
stability,which means that it is
widely used in areas where resistance to high temperatures is
3. Good wear resistance : Alumina ceramic is the material of choice
for alumina wear parts.
4. High electrical resistivity : Alumina is an electrically
5. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and
alkaline solutions. Good chemical stability of alumina leads to
high corrosion resistance.
1. High heat resistance : Zirconia ceramic has excellent thermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
2. Good wear resistance : Zirconia ceramic is the material of
choice for wear parts.
3. High corrosion resistance : It is insoluble in water and only
slightly soluble in strong acid and alkaline solutions. Good
chemical stability of alumina leads to high corrosion resistance.
Alumina ceramic is the most mature of the engineering ceramics,
offering excellent electrical insulation properties together with high hardness and good wear
resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally
white but may also be pink or ivory.The color is derived from either the sintering additives or
impurities in the raw materials.
