[separator headline="h2″ title="Aluminum Nitride Alternative – Shapal HiM Soft Machinable AlN"] Shapal Hi M Soft is a machibale Aluminum Nitride that keeps many of the desirable properties of pure AlN, but has the added advantage of being easily machined into custom pieces.
Aluminum Nitride Properties While AlN is not a ''new'' material, recent manufacturability developments over the past 15 years have made this an exciting and viable ceramic design material. One of the most useful applications AlN has found is in replacing beryllium oxide (BeO) in the semiconductor industry. This substitution is due to BeO''s toxicity.

Plane honing machining of aluminum nitride (AlN) was investigated in this study. AlN has advantageous thermal and dielectric characteristics and is in great demand as a semiconductor mounting board or packaging parts material. However, as AlN is a sintered material, the AlN grains readily detach during machining making it difficult to obtain fine surface roughness at high efficiency.
Nov 11, 2019· Machining Grinding of Aluminum Nitride Aluminum Nitride can be machined into fully dense states in the form of green biscuits. In Green biscuit form it can be machined easily into any complex geometry. However, the sintering process followed during Machining Aluminium Nitride can fully densify the material. It causes the AlN body to shrink 20 ...

While the grinding of beryllium oxide requires stringent dust control during the grinding process it otherwise machines like other technical ceramics of the same density and grain size. Intricate design features are no more or less difficult than other materials such as alumina or aluminum nitrideAlN and delivery times are similar as well.
Aluminum nitride is stable at high temperatures in inert atmospheres and melts at 2800 °C. In a vacuum, AlN decomposes at ~1800 °C. In the air, surface oxidation occurs above 700°C, and even at room temperature, surface oxide layers of 510 nm have been detected. This oxide layer protects the material up to 1370°C.

Aluminum nitride (AlN) has ultrigh thermal conductivity, excellent electrical insulation, low dielectric loss, thermal expansion coefficient close to silicon, and excellent plasma resistance. Aluminum Nitride is one of a few materials which has both high thermal conductivity and electrical insulation.
hot pressed aluminum nitride overview. Hot pressed aluminum nitride (AlN) is used in applications requiring high electrical resistivity in additional to exceptional thermal conductivity. The applications for hot pressed AlN typically involve rigorous or abrasive .
AlN is somewhat more challenging than some other technical ceramic because the fine grained grinding powder adheres to the diamond tooling requiring frequent wheel dressing to allow for efficient stock removal without excessive preassure and localized heating. Otherwise, Aluminium nitride machines like other technical ceramics. ALN can be drilled, threaded, and ground with the same basic ...
