Carbon/Graphite and Electrographite Materials can be manufactured net shape to offer the most cost effective solution and provide high volume capability or is easily machined into a variety of configurations, tolerances, and surface finishes.Typical tolerances are ± 0.005" to ± 0.020 with some down to ± 0.001".

Graphitization is another heating process where the parts are heat treated at extreme temperatures that range between 2700° C to 3000°C or 4900° F to 5450° F. The result of the process is the changing of the carbon in the part to crystalline graphite, which changes the physical properties of the material.

Graphite Heat Exchangers, Columns, Ejectors. GRAPHITE is an allotrope of carbon (softer than the gemstone diamond, but brittle) having crystalline form categorized as a non-metal that still conducts electricity. Synthetic Graphite is impregnated with resins (phenolic or PTFE) and is suitable for handling various corrosive applications.

US-2017044017-A1 chemical patent summary.

GAB Neumann exclusively uses graphite from western sources (United States of America, Europe or Japanese suppliers only). Our process uses a homogenous, fine-grain graphite with a compact grain structure, an optimal grain and pore size distribution, rendering it exempt from structural irregularities such as cracks, large pores, or impurities.

The process, called graphitization, results in Crystallization of amorphous precursor carbon, which transforms into crystalline graphite. During this high temperature tratment graphite is also purified since most its impurities (binder residues, gases, oxides, sulfur) vaporize.

Mersen graphite continuous casting dies are the ideal solution for casting copper alloy, precious metals, and cast-iron products. Iso-molded graphite is used in the metal-casting process and allows the metal processing to be monitored continuously through various stages of melting from the liquid state to the solid state resulting in semi-finished products such as wires, bars, tubes, and strips.

With slight changes to the manufacturing process you can create a diverse range of graphite making it useful in a wide variety of applications. High-quality Isostatic Graphite

Commercial flake graphite products are available in a range of purities from around 80% carbon up to 99+ percent carbon. Flake which is in the purity range of 80-98% typically represent materials which have been beneficiated using only froth floatation. Flake above 98% purity has been purified using other methods subsequent to floatation.
