Learn about anti-seize compounds for thread protection and galling prevention.
Introduction to Anti-Seize Technology
Anti-seize compounds are essential for preventing galling, seizing, and corrosion in threaded connections. The selection depends on service temperature, chemical exposure, and compatibility requirements.
Copper-Based Anti-Seize Compounds
Copper-based compounds are the most common formulation, offering excellent lubricity up to 982°C (1800°F). However, they should not be used on stainless steel or titanium where galvanic corrosion concerns exist.
Nickel and Specialty Formulations
Nickel-based compounds provide protection for stainless steel and titanium alloys. These formulations withstand temperatures up to 1315°C (2400°F).
| Type | Max Temp (°C) | Best Use |
|---|---|---|
| Copper | 982 | Steel, brass |
| Nickel | 1315 | Stainless, alloys |
