In the field of grinding, the choice of abrasive material directly affects machining efficiency, surface quality, and cost. White Fused Alumina (WA), Black Silicon Carbide (C), and Green Silicon Carbide (GC) are three of the most commonly used conventional abrasive wheels, each with distinct advantages and applications.
Key Advantages of White Fused Alumina Grinding Wheels:
Low grinding heat：Lower toughness causes abrasive grains to fracture easily during grinding, creating new cutting edges. Good self-sharpening, low heat generation, less risk of workpiece burning.
High surface finish：Ideal for precision grinding and thin-walled parts.
Applicable materials：Hardened steel, high-carbon steel, high-speed steel, alloy steel, and other high-tensile-strength materials.
Key Advantages of Black Silicon Carbide Grinding Wheels:
Sharp grains：Higher hardness than WA, strong cutting force, high grinding efficiency.
Good self-sharpening：Brittle nature allows timely shedding of dull grains, maintaining sharpness.
Applicable materials：Metals with low tensile strength and non-metallic materials—cast iron, brass, aluminum, copper, stone, rubber, refractories, etc..
Key Advantages of Green Silicon Carbide Grinding Wheels:
Extremely high hardness：Hardest among the three, second only to diamond and boron carbide.
Sharp and highly brittle：Extremely sharp cutting edges, ideal for ultra-hard and brittle materials.
Good thermal conductivity：Reduces risk of thermal deformation.
Applicable materials：Cemented carbide, optical glass, ceramics, agate, semiconductor materials, etc..
