How to Select Carbon and Graphite Materials

Choose carbon evaporation materials when the material is used as a coating source for thermal evaporation, vacuum deposition, or PVD coating systems.

Choose carbon/graphite sputtering targets when the material is used in sputtering equipment and requires controlled diameter, thickness, purity, surface finish, backing plate, or bonding.

Choose graphite crucibles for small-volume melting, evaporation, laboratory heating, thermal analysis, or high-temperature testing.

Choose graphite foils, sheets, or plates when the final part is flat, thin, plate-like, or used as a gasket, heat shield, insulation layer, electrode, or flat machining blank.

Choose graphite rods, bars, or blocks when the material will be machined into electrodes, molds, dies, fixtures, spacers, support parts, or custom graphite components.

Choose graphite tubes, rings, or sleeves when the part requires an inner diameter, hollow structure, spacer, collar, bushing, sealing ring, or cylindrical furnace component.

Choose custom carbon or graphite stock shapes when standard sizes cannot meet the required geometry or when cut-to-size blanks can reduce machining waste.

FAQs

Carbon evaporation materials are used as source materials that are heated and evaporated in a vacuum coating system, while carbon sputtering targets are solid targets bombarded by plasma ions in a sputtering process. Both are used for thin-film deposition, but the required form, density, surface finish, and system compatibility are different.

Carbon evaporation materials can be supplied as pellets, pieces, granules, rods, slugs, or custom evaporation charges. The suitable form depends on the evaporation source, loading method, coating system, required purity, and film deposition process.

Yes. Carbon and graphite sputtering targets can be reviewed with backing plate bonding when required by the sputtering system. Please provide the target diameter or rectangular size, thickness, backing plate material, bonding requirement, hole pattern, and operating conditions.

The right graphite grade depends on grain size, density, strength, machinability, surface finish requirement, and final part geometry. Fine-grain or isostatic graphite is often preferred for precision machining, EDM electrodes, molds, fixtures, and detailed graphite components.

High-purity graphite is used in vacuum, PVD, semiconductor, laboratory, and high-temperature applications where low contamination, low ash content, thermal stability, and chemical cleanliness are important.

Yes. Graphite plates, rods, tubes, blocks, discs, and rings can be machined into custom blanks, electrodes, spacers, sleeves, fixtures, molds, crucibles, and other graphite components. Machining feasibility depends on material grade, size, wall thickness, tolerance, and drawing details.

For a custom graphite crucible, please provide OD, ID, height, wall thickness, cavity size, capacity, material grade, working temperature, atmosphere, quantity, and drawing if available. The application, such as melting, evaporation, thermal analysis, or laboratory heating, also helps material selection.

Yes. Custom-cut carbon and graphite stock shapes can reduce machining time and material waste when the final part does not match standard plate, rod, tube, block, disc, or ring sizes. Near-net blanks, drilled blanks, grooved blanks, and pre-machined forms can be reviewed according to drawings.
