Cheap price electrical insulation Alumina Ceramic Substrate for sale
1. Description
Alumina is the most cost effective and widely used material in the family of engineering ceramics. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. With an excellent combination of properties and an attractive price, it is no surprise that fine grain technical grade alumina has a very wide range of applications.
We manufactures custom technical ceramics, covering a wide range of customer requirements .We make use of several forming and machining techniques to process components made from alumina Ceramics, This material may be used in applications that require High elevated temperatures ,High dielectric strength, excellent electrical resistance . wear or corrosion resistance .high temperature capability .High Electrical insulation.

Notice for Using
1. Alumina ceramic products are fragile. Please handle them carefully and avoid collision during unpacking, transportation, handling and cleaning
2. Check whether any micro-cracks exist before using alumina ceramic products. Products with micro-cracks should not be used.
3. Alumina ceramic products should be completely dry before usage. If they get wet, let the crucible or tube dry naturally before using them.
5. Pacakage
We often use carton box ,wooden box and pallet to pack Alumina ceramic substrate.
We have professional logistic company, they can deliver to any port in the world and they can offer very good price.
