Nickel, aluminum, and graphite are blended into a high performance lithium complex grease, providing protection up 2600°F. Nickel Guard Premium™ is used where copper can not be present, and maximum protection is required. Because of the hardness of the nickel particle, Nickel Guard Premium™ performs particularly well when surfaces are under extreme pressure. It is the preferred product when working with high alloy steels, or very dissimilar metals. The burr-like shape of the nickel particle makes it the recommended anti-seize for preventing galling when assembling stainless steel fasteners, fittings or pipe. Speciality grades available upon request.
