Thermal Conductive Alumina Ceramic Plates / Alumina Substrate for
Heatsink
95% alumina ceramic plate is a kind of ceramic part which is made
of 95% alumina material. It is white color, wear resistant, acid
and alkali resistant, corrosion resistant and high temperature
resistant (1600-1700℃). The alumina ceramic chip has the characteristics of good
chemical stability, high insulation resistance and strong
adsorption capacity, is a kind of excellent electrical insulation
and wear-resistance material. The alumina ceramic products are
widely used in lamp holder, lamp header, blast nozzle, automobile
components and other wear resistance parts.

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:
Diameter: Average approximately 14.00" +/-0.010" (381 mm)
Thickness: Average approximately 0.435” +/-0.010" (11 mm )
Please Note: There are visually discernible differences in any or all of the
dimensions. These are not precision technical ceramic components.
There is no warp or camber Specification for this item. However
they are relatively flat. There may also be “firing” color
variations inherent in the material. Some my have minor edge
chatter or small edge chips. 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.

Main Features:
1) High hardness.
2) High heat resistance: alumina ceramic has excellentthermal
stability,which means that it is widely used in areas where
resistance to high temperatures is essential.
3) Good wear resistance: alumina ceramic is the material of choice
for alumina wear parts.
4) High electrical resistivity: alumina is an electrically
insulating material.
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.
