There are few fastener materials that can withstand prolonged exposure to temperatures up to 1600°C and many such applications in which failure, or easy replacement, is not an option. Now, when facing this problem, you'll have the solution… Solid Ceramic Fasteners from Ceramco, Inc.
High Temperature Resistance
This is referred to as its: Maximum Service Temperature. In this instance, higher is better. Fasteners made of Ceramco's alumina A998 have a maximum service temperature of 1650°C. Our zirconia fasteners are rated at a maximum service temperature of 2200°C.
Heat Transfer Resistance
Solid ceramic fasteners extend their heat resistance even further in another inherent property to not transfer or conduct heat: Thermal Conductivity. Ceramco’s solid alumina ceramic fasteners thermal conductivity is very low (lower is better). Our solid zirconia ceramic fasteners are almost 10 times lower than our alumina counterpart!
Strength
Ceramco utilizes two manufacturing techniques resulting a solid ceramic fastener that is also strong.
1. Fully molding the solid ceramic fastener, including the threads to avoid machining, as it is the machining that weakens the ceramic.
2. Full density firing of the solid ceramic fastener; the ceramic composition determines the length of time it can fired.
Solid ceramic fasteners (like all fasteners) have limits to their strength ratings. These characteristics are called: Mechanical Properties. When not over-torqued, or subjected to impacts, Ceramco’s solid ceramic fasteners deliver consistent, reliable and long-lasting performance in high temperature environments.
