White Fused Alumina (WFA)
Produced from high-purity aluminum oxide powder through electric arc furnace smelting, WFA is a premium abrasive material characterized by its snow-white appearance, exceptional hardness, and controlled toughness. With ≥99% Al₂O₃ purity, it delivers superior grinding performance through excellent self-sharpening properties, high material removal rates, and minimal heat generation during operation.
Graphitized Petroleum Coke Recarburizer(GPC)
GPC is produced by graphitizing premium petroleum coke at ultra-high temperatures (2,500–3,500°C), resulting in a high-purity carbon material characterized by ≥98% fixed carbon, ultra-low sulfur (≤0.05%), minimal ash (≤0.5%), and controlled porosity.
Calcined Petroleum Coke Recarburizer (CPC)
Petroleum coke is a carbon by-product of the petroleum refining process of thermal decomposition or “cracking” of the high-boiling hydrocarbon molecules contained in mineral oil and their subsequent coking at high pressure. For subsequent industrial use, the petroleum coke must be thermally cleaned in a “calciner” at temperatures of approx. 1400°C. The “calcined petroleum coke” is thus created.

Silicon Carbide SiC 80%-85%
Silicon carbide, also referred to as carborundum or black diamond grit, typically appears in dark gray to jet-black hues with a glass-like or semi-metallic luster.
Silicon carbide is renowned for its extraordinary combination of high hardness, superior thermal conductivity, and chemical inertness, enabling critical roles in extreme environments. These properties make it indispensable for applications ranging from abrasives to refractories。
Amorphous Graphite FC 75%-80%
Amorphous graphite, also known as microcrystalline graphite or black lead powder, exhibits a steel-gray or dark gray color with a metallic luster.
