Extra-Strength Fracture- and Thermally
Shock-Resistant Silicon-Nitride Ceramic Sheets
- Color: Gray
- Maximum Temperature: 1,830° F
- Fabrication: Fired
- Dielectric Strength: 254V/mil
- Porosity: 0%
- Compressive Strength: 580,000 psi
Pressed into ultra-dense sheets, these silicon-nitride ceramic sheets resist deforming, expanding, or cracking when compressed, bent, or exposed to quick temperature changes. They’re just as strong and fracture resistant as zirconia ceramic, and hold their strength and shape at higher temperatures. All are stronger, harder, and more fracture resistant than most other ceramics.
Use these sheets for high-stress parts, such as engine parts. You can even use them as a substrate or insulator for electronic parts, such as computer chips. Since they stand up to temperature swings better than silicon carbide and mullite, they’re also good for use in furnaces and immersion heaters. Able to withstand wear, these sheets can be used to make cutting and roughing tools.
These sheets hold up to harsh chemicals, such as acids, but may corrode from nitric acid. They are not as corrosion resistant as silicon carbide.

Extra Thermally Shock-Resistant Single-Closed-End SiAlON Ceramic Tubes
- Color: Gray
- Maximum Temperature: 1,830° F
- Fabrication: Fired
- Porosity: 0%
- Compressive Strength: 510,000 psi
Often used as a protective shield in thermocouples and other conditions with drastic climate changes, these SiAlON ceramic tubes won't deform, expand, or crack when repeatedly exposed to large temperature changes. Submerge the closed end of the tube into harsh settings, such as tanks and furnaces, to protect contents from coming into contact with harmful liquids and gases.
These tubes are stronger and resist thermal shock better than mullite and alumina, though they don’t remain as stable in ultra-high temperatures. They're not as hard as silicon carbide, so they shouldn't be used when wear resistance is necessary. Because they hold up to chemicals, they’re good for use with molten metal, such as aluminum and zinc. Similar to nonporous alumina, these tubes help seal out gas and liquids.

Fast-Cutting Carbide Square End Mills for Stainless Steel and Titanium
Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. They have a high helix angle and a wear-resistant coating for excellent shearing and chip removal in stainless steel and titanium. Made of solid carbide, they are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. End mills have a square end for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
Titanium-aluminum-silicon-nitride (TiAlSiN) coated end mills are extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures.
