Abrasive Selection Table for Cylindrical Grinding Wheels

Abrasive	Core Features	Suitable Workpiece Materials	Applicable Industries
WA（White Aluminum Oxide）	High hardness, moderate toughness, sharp cutting, good self-sharpening, low risk of workpiece burn, most versatile	45# carbon steel, common alloy steel, hardened & tempered steel, standard shafts, bearing steel, cast iron	General machinery, bearings, standard hardware, basic automotive parts
（RA/PA）Pink Aluminum Oxide	Contains chromium oxide, finer grinding texture, better polishing than WA, higher toughness, superior surface finish	Bearing steel, die steel, precision carbon steel, small stainless steel parts, slender shafts	Precision bearings, precision molds, medical devices, high-precision auto parts
（32A）Single Crystal Aluminum Oxide	Single-crystal structure, balanced hardness & toughness, resistant to grain fracture, durable, low heat generation under heavy feed	High-hardness alloy steel, hardened steel, high-toughness shafts, hydraulic precision spindles	Hydraulic components, engineering machinery shafts, high-end precision machining
（CX）Microcrystalline Aluminum Oxide	Micro-fine grains, ultra-smooth surface, micro-cutting action, excellent dimensional consistency, low grinding heat	Ultra-precision slender shafts, probes, micro precision shafts, optical metal components	Precision electronics, instrumentation, aerospace micro parts, semiconductor components
（GC）Green Silicon Carbide	Extremely high hardness, brittle, sharp cutting, not for hard steel, specialized for hard non-ferrous / non-metallic materials	Carbide tools, tungsten steel, copper, aluminum, hard ceramics, graphite	Tool manufacturing, ceramic processing, non-ferrous metal finishing, tungsten steel die sharpening
（C）Black Silicon Carbide	Lower cost, medium sharpness, slightly better toughness than GC, top choice for non-ferrous rough grinding	Aluminum parts, copper parts, cast iron, stone, plastics, soft non-metallics	General non-ferrous rough machining, hardware rough grinding, stone processing
