Silicon carbide offers ideal properties for low tensile strength metals like aluminum. It is often combined with blast media such as brown or pink aluminum oxide for smooth finishes.
This abrasive is attached to sandpaper or wheels and discs so users can make controlled cuts without excessive heat production, providing even, even cuts without creating excess friction or heat build-up. Furthermore, it’s safer for workers and the environment than silica-based alternatives.
High-Temperature Strength
Silicon carbide is an extremely durable material, boasting high tensile strength and fracture toughness ratings that resist crack propagation. Furthermore, its Young’s modulus and flexural strength is high, offering resistance against bending stress – making it an excellent choice for use in abrasive blasting applications.
Washington Mills is the largest North American producer of alpha, high quality silicon carbide macrogrits, microgrits and powders known collectively as CARBOREX(r). These abrasives can be used to grind, cut, shape and polish materials such as glass, ceramics, stone cast iron and nonferrous metals; their hard grains quickly penetrate materials for minimal wear-and-tear and reduced operating costs.
RockRidge silicon carbide (SiC) is an extremely tough, durable and versatile raw material used across a range of industrial applications. Produced through heating silica sand with petroleum coke in an electric resistance furnace, SiC is available in two forms – Black silicon carbide and Green silicon carbide – giving users plenty of options when choosing their material source.
SiC offers high temperature strength, excellent oxidation resistance, thermal shock resistance and fracture toughness; chemically stable properties include excellent thermal conductivity and low coefficient of expansion; it makes an ideal material choice for applications involving physical wear resistance such as ceramic refractories or shot blast nozzle production.
High Thermal Conductivity
Silicon carbide’s hard and sharp abrasive grains outlast aluminum oxide’s, meaning fewer blast cycles and decreased waste, translating to significant cost savings over time.
This unique material is exceptionally pure and can be manufactured into complex bonded shapes as well as used loose abrasively for various applications and industrial needs. A popular use for it is in abrasive blasting, where specialized machinery uses media projected at high speeds across a surface to blast away rust, prepare products for painting or remove old finishes from surfaces. Due to its low thermal expansion and thermal conductivity properties, alumina makes an excellent material choice as it won’t warp or crack under high temperatures generated during this process.
Ceramic materials feature crystalline structures which contribute to their durability and strength, particularly when it comes to producing abrasive products like blasting grains and compounds. An abrasive is formed through reacting silica with carbon in a special reactor; then this greenish black powder can be utilized for manufacturing various industrial tools and abrasives.
CARBOREX provides more than just an excellent abrasive blasting option; it also makes an excellent lapping pad, ceramic lapping pads, polishing glass and granite, lapping metals, ceramics and polishing solutions as well as polishing glass and granite polishes. Furthermore, CARBOREX makes intricate designs easier than ever!
High Resistance to Corrosion
Silicon carbide has proven itself as an exceptional corrosion-resistant material, making it the go-to choice for applications in harsh environments. It can withstand mechanical strain and temperature variations without incurring damage or degradation; an essential feature when operating within chemical environments where corrosion or aggressive chemical conditions exist.
Solid state-sintered silicon carbide (SSiC) and silicon-infiltrated silicon carbide (SiSiC) ceramics boast outstanding tribological properties [1, 2], making them well suited to wear applications where their combination of hardness and structural integrity helps guard against deformation under stress. Furthermore, their chemical inertness ensures they won’t become exposed to chemicals quickly enough for oxidization to take place compared with other materials which quickly oxidize in hostile environments.
Silicon carbide’s high melting point and excellent high-temperature resistance enable it to withstand harsh conditions that would quickly wear away other ceramic materials, while its insolubility in most water-based substances such as acetone, alcohol and acids enhances its chemical inertness and makes it suitable for harsh conditions that might otherwise lead to corrosion in other materials.
Washington Mills manufactures alpha-silicon carbide macrogrits, microgrits and powders known as CARBOREX(r), designed for superior performance in various applications. These abrasives can be used as blast media in grinding, cutting, shaping and honing various materials like cast iron, ceramics and nonferrous metals like aluminum and copper alloys; in refractories; wire sawing abrasives and anti-slip applications – tailored specifically to your unique application! These grit sizes, particle size distribution standards as well as chemical composition standards tailored for your specific applications – perfect!
Environmentally Friendly
Silicon carbide media is highly durable, lasting through many blast cycles before needing replacement. Its narrow pointed edges make it suitable for ceramics, glass, stone, marble, fiberglass and non-ferrous metals such as non-ferrous metals such as fiberglass. Plus it etching well allowing preparation surfaces for coatings or restoration work! However, this costly option might not be appropriate for wood or harder metals like steel.
Silicon carbide abrasive doesn’t damage parts in high-pressure environments as much as other abrasives do, because it works by flow rather than impact. Furthermore, this media’s durability reduces waste while decreasing your carbon footprint.
Green silicon carbide is an extremely hard abrasive material produced from melting quartz sand and petroleum coke in an electric resistance furnace. Due to its toughness and ability to withstand very high temperatures, green silicon carbide makes an excellent material for use in abrasive blasting applications.
Silicon carbide abrasive is an ideal choice for smoothing wooden furniture or metal surfaces, and its durability and versatility make it the go-to product for both professionals and DIYers alike.
