Product Description

 

Product Description

Material Introduction:

Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.

Main Features of al2o3 plate:
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.

 

1. High thermal conductivity, up to 25 W/m.k at room temperature and low coefficient of thermal expansion
2. Good thermal shock resistance, greater than 220 T(ºC) and refractory with high - temperature resistance
3. Good surface roughness, flatness to be 0.05 mm and very smooth texture with super tiny grain size
4. High dielectric strength, high electrical resistivity, low dielectric constant, and dielectric loss.
5. Laser cutting or precision machining cutting makes tight tolerance for precision fitting easily
6. Quicker heat dissipation than cooper and aluminum metal materials and increase the service life
7. Anti-aging, resistance to oxidization and free of rusty forever, also chemical stability to in harsh conditions
8. Low density, over 3.65 g /cm3, with lightweight, its benefits to design the device lighter.

The main forming method we use is tape-casting, Isostatic pressing. We are dealing with a variety of selection of thickness from 0.15 mm to 20 mm, whatever, it's prototyping needs or mass production for cost down. We could offer you an ideal solution.
