Specifications of 95% 99% Alumina Ceramic Parts Alumina Ceramic Substrate

Alumina ceramic parts and substratums made from 95% and 99% alumina content serve high-performance applications. These products incorporate toughness, durability, and resistance to extreme problems. The 95% alumina ceramic offers an equilibrium in between expense and efficiency. It functions well in atmospheres requiring excellent mechanical stability and modest thermal resistance. The 99% alumina ceramic gives superior residential properties for even more demanding usages. Its greater purity increases thickness, solidity, and resistance to use and rust.

Both qualities withstand temperature levels approximately 1600 ° C. They preserve architectural stability under fast thermal shifts. This makes them ideal for furnace components, semiconductor handling, and aerospace systems. The low thermal development coefficient lessens deformation under warmth. Chemical inertness guarantees compatibility with acids, alkalis, and solvents. This stops deterioration in severe industrial or laboratory setups.

Electric insulation is a crucial feature. Alumina porcelains block high voltages even at elevated temperature levels. They serve as reliable substrates for electronic circuits, sensors, and insulators. The smooth surface area allows precise printing of conductive pathways. High-frequency signal stability makes them perfect for RF and microwave devices.

Mechanical buildings include high compressive strength and rigidity. 99% alumina stands up to abrasion better than steels or plastics. It lasts longer in pumps, valves, and reducing tools. The product’s solidity minimizes friction in moving components. Custom shapes are possible with machining or molding. Tolerances as limited as ± 0.1 mm satisfy accuracy design demands.

Surface finishes vary from brightened to rough appearances. Sleek alumina reduces friction in seals or bearings. Rough surfaces improve attachment in coatings or bonding applications. Shades differ from white to ivory depending on pureness and additives.

95% alumina matches cost-sensitive jobs needing dependable performance. 99% alumina fits extreme problems where failure is undesirable. Both grades comply with ISO and ASTM criteria for product consistency. Manufacturers examine sets for thickness, porosity, and fracture resistance. Quality checks make certain parts satisfy specifications prior to delivery.

Applications cover electronic devices, auto, medical, and energy sectors. Common usages consist of circuit carriers, laser tubes, use plates, and protecting washing machines. Clinical implants benefit from biocompatibility and sterilization resistance. Custom-made sizes and geometries adjust to distinct style needs.

5 FAQs of 95% 99% Alumina Ceramic Parts Alumina Ceramic Substrate

What is the difference between 95% and 99% alumina ceramic parts? The main difference is the aluminum oxide content. 95% alumina parts contain 95% aluminum oxide mixed with other materials. 99% alumina parts have a higher purity. This makes 99% alumina harder, denser, and more resistant to wear. 99% alumina also performs better in extreme heat or harsh chemicals. 95% alumina is cheaper and works well for less demanding applications.

Can alumina ceramic parts withstand high temperatures? Yes. Alumina ceramic handles high heat well. 95% alumina parts work up to 1500°C. 99% alumina parts survive up to 1700°C. They do not melt or crack easily under thermal stress. This makes them ideal for furnaces, engines, or high-temperature sensors.

Are alumina ceramic substrates good for electrical insulation? Yes. Alumina ceramics do not conduct electricity. They have high electrical resistance even at high temperatures. This makes them perfect for insulating electronic components. They are widely used in circuit boards, power electronics, and semiconductor equipment.

How smooth is the surface of alumina ceramic parts? Surface finish depends on the manufacturing process. Standard parts have a slightly rough texture. Precision polishing can create mirror-like surfaces. Smooth surfaces reduce friction and wear in moving parts. Roughness is measured in microns. Most industrial parts use surfaces between 0.2 and 1.6 microns.

How do I clean and maintain alumina ceramic parts? Clean them with mild soap and water. Avoid harsh chemicals or abrasive cleaners. Dry them thoroughly after cleaning. Check for cracks or chips regularly. Replace damaged parts to avoid failure. Store them in a dry place to prevent moisture absorption. Handle them carefully to avoid breaking them.
