Materials available include
Extruded Graphite– This grade of graphite is manufactured by pressing a fine graphite powder blended with pitch or another binder through a die under pressure. The resulting shape is then fired, impregnated, fired again, and graphitized at 2000℃. Extruded graphite grain size is approximately 10x larger than Isostatically Pressed Graphite, but it is more economical to produce.
Isostatically Pressed Graphite- Also known as Isographite or Isotropic Graphite is a grade of graphite manufactured by taking a fine grain graphite powder blend and placing it in a hot isostatic press. The completed pressed cylinder or block is then further heat treated to fully solidify, densify, modify, and purify the material to the final crystalline structure and properties desired.
Vibrated Graphite – The most notable feature of vibrated graphite is the ability to produce larger requested sizes. The graphite is less dense then the other grades but is a perfect solution and cost effective when high strength is not required. It has an exceptionally homogeneous structure, almost isotropic properties, and low ash content.
Molded Graphite – This grade of graphite is similar to Isographite, but imported. It is manufactured by using a graphite powder mix and applying pressure in one direction. This type of production relies on the mold shape to hold pressure in comparison to Iso-static which applied pressure evenly in all directions. While this grade is not as isotropic in properties, it is the perfect solution when added cost and Isographite uniformity is not required. Typically, it is used for high volume applications and shapes such as washers.
Insulating Firebricks – also known as soft bricks or IFB, are used in high temperature applications ranging from 2,000°F (1,093°C) to 3,200°F (1,760°C). The bricks are manufactured from high purity refractory clays and other ceramic raw materials according to international standards, and are suitable to operate in various temperatures and atmospheres up to 3000°F. IFB bricks do contain a carefully graded organic filler which is burned out during the manufacturing process to provide a uniform controlled pore structure. This high porous rate provides excellent insulating properties while contributing to the bricks lightweight.
Hard bricks – also known as Super Duty or High Alumina, are very hard, dense, and durable refractory bricks. The bricks are manufactured with select bauxite chamotte as the main raw ingredient and fired at 1450-1470℃ using an advanced process with strict quality compliance. These bricks are not insulating in comparison to their IFB counterparts. Special tools, such as a tile or brick saw, are required for cutting and modifying the bricks. Typically used for their structural qualities and on the inside of kilns because they absorb and conduct heat easily, which permits the high temperatures needed in firing. Often used as the main building component of large kilns, chimneys, fireboxes, and burner ports- anywhere around direct flame. Hard bricks are typically used in tandem with insulating firebricks to provide an excellent complete solution for refractory applications.
Molybdenum – also known as Moly, is a refractory metal with a well-balanced range of properties making it a great solution for many different industries and applications. Moly, with a melting temperature of 4760℉, is useful in many high temperature applications where melting temperatures are a concern. In comparison to tungsten and tantalum, it has the third highest melting point. The metal’s extraordinary resistance to heat is possible thanks to the material’s high energy binding of individual atoms. This binding permits the use of the metal in many industrial applications that would not be feasible with common metals and alloys. Moly’s high melting point, excellent strength at elevated temperatures, low coefficient of thermal expansion, and high level of thermal conductivity make this the ideal solution for many applications. Additionally, Moly is softer and more ductile than tungsten contributing to its machinability but can also be alloyed with other compounds to increase specific performance attributes. Refer to alloys of Molybdenum such as Mola and TZM listed below.
Titanium-Zirconium-Molybdenum alloy – also known as TZM, contains 0.50% Titanium, 0.08% Zirconium, and 0.02% Carbon. TZM is manufactured from molybdenum by using small quantities of tiny, extremely fine carbides through P/M or Arc Casting technology. This alloy is a great high strength solution for high temperature applications. The alloy is stronger than pure molybdenum and possesses a higher recrystallization temperature and better creep resistance. Commonly used in applications involving demanding mechanical loads, it’s recommended use temperature is between 700℃ & 1400℃.
Molybdenum-Lanthom Oxide – also known as Mola, is an alloyed metal providing specific advantages over pure Moly. This alloyed metal is made by adding Lanthanum Oxide during the manufacturing process, giving the molybdenum a so-called stacked fiber microstructure which is stable at temperatures up to 2000℃. This special microstructure allows the alloy to be creep-resistant even under extreme use conditions. Additionally, the alloy has a lower cold shearing strength, higher tensile strength, and greater resistance to deformation at high temperatures. The alloy is an ideal materials for applications requiring dimensional stability and strength at temperatures above the capabilities of pure Moly or TZM. Common machining is done to produce furnace components such as stranded and other wires, sintering and annealing boats or evaporator coils. In the lighting industry, molybdenum-lanthanum oxide is used for example for retaining and feed wires.
