The product is available in.

Aln ceramic plates. While in the green or biscuit form it can be machined relatively easily into complex geometries. Aluminum nitride aln is a unique ceramic material that combines high thermal conductivity with high electrical resistivity. However the use of beo is restricted due to its toxicity and c bn is. Unipretec s standard aluminum nitride ceramic substrate s are in thickness.

Outstanding hardness scratch resistance and high strength high quality. Available in large sizes up to 18x35. Aluminum nitride can be machined in green biscuit or fully dense states. Beryllium oxide beo and cubic boron nitride c bn are virtually the only other examples.

Aluminum nitride machining grinding. 1 piece pieces 0 5mm 1mm thick aluminum nitride aln ceramic plate the description of the aln ceramic plate aln ceramic plate is one of the most popular technical ceramic substrate which offer exceptional thermal conductivity excellent heat. Many are man made i e. A high thermal conductivity ceramic substrate based on aluminum nitride ain having thermal conductivity about seven times greater than that of alumina.

What types of ceramic do you supply. Metallized ceramic substrates have a structure in which metal plates are bonded to both sides of the insulating ceramic substrate as discussed in section 3 1. Non oxide ceramics aluminum nitride aln ceramic material with very high thermal conductivity aluminum nitride aln is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. Export carton supply ability.

Excellent clarity and no inherent birefringence durable. High optical transmission 85 near uv to mid ir wavelengths 0 25 to 4 0 μm crystal clear. 0 5mm 1mm thick aluminum nitride aln ceramic plate. Denka an plate is a high thermal conductivity ceramic substrate based on aluminum nitride having thermal conductivity several times greater than that of alumina.

They do not occur naturally e g. Alumina al2o3 in purity from 90 to 99 7 aluminium nitride aln cordierite hot pressed boron nitride. Silicon nitride and their properties can be enhanced to produce very high strength at high temperatures good corrosion resistance etc. High thermal conductivity aln aluminum nitride ceramic substrate sheet plate.

However the sintering process that is required to fully densify the material causes the aluminum nitride body to shrink approximately 20. Aluminum nitride substrate aluminum nitride plate aluminum nitride disc manufacturer supplier in china offering low dielectric constant aluminum nitride aln ceramic substrate plate slow open brass cartridge slow open brass cartridge plastic quick open cartridge plastic quick open cartridge and so on. Excellent refractive index homogeneity over large areas commercially available. The metal plate on one side functions as a conductor circuit while the one on the other side functions as the heat spreader while playing the role of an electrical insulator between a semiconductor device and the heat sink and the.

High thermal conductivity and excellent electrical insulation are the two main properties of aluminum nitride ceramic.
