Graphite Rods & Tubes (Metaullics)
Specialty graphite rods and tubes are available in a wide variety of grades and sizes. Our complete line of graphite rods and tubes is available purified and/or machined to meet your specifications. Graphite provides unique operating characteristics. The strength of this material increases as temperatures rise. It has exceptionally good corrosion resistance and is virtually immune to thermal-shock damage. Dimensional and thermal stability remain constant at temperatures up to 2600°C (4712°F). Because erosion resistance is excellent and this product is non-fatiguing, there are no changes in properties with age or cyclical operation.
GSXP—a basic grade of fine grain, purified graphite. It has densities, strengths and resistivities typical of single-step impregnated graphite. Normal ash levels are less than 50 ppm, and the structure is uniform and free of flaws and laminations.
G-83—a high-performance, reduced permeability graphite grade with uniform structure, produced to a typical density of 1.83 g/cc (1.05 oz/in3) for aerospace and other selected applications.
G-Grade—graphites produced in this category are reduced in permeability by filling the pores of the base stock with a graphitized material. These graphites have a fine-grain structure, featuring high strength, high density and excellent resistance to erosion.
G-90—similar to G-83, but with a minimum density of 1.90 g/cc (1.1 oz/in3) and reduced permeability.
