F14 black silicon carbide is a coarse-grain abrasive known for high hardness, strong cutting capacity, and excellent self-sharpening performance. It is widely used as a raw material for fiber backed sand discs, grinding wheels, and coated abrasives, especially for heavy-duty grinding, rust removal, and fast material removal in metal casting, steel structures, and shipbuilding.

What Is F14 Black Silicon Carbide?

F14 black silicon carbide is a high-efficiency industrial abrasive widely used in grinding wheels, coated abrasives, and fiber backed sand discs. As a coarse-grain abrasive with strong cutting capacity, it is designed for heavy-duty grinding and fast material removal. Its superior performance makes it a preferred raw material for high-quality fiber sand discs.

Main Applications of F14 Black Silicon Carbide Fiber Backed Sand Discs

F14 coarse-grain sand discs focus on heavy grinding and rapid material removal, covering diverse industrial scenarios:

• Metal casting industry – quickly clean casting flashes, gates and risers, and remove surface hard scales and oxide layers.
• Steel structure and heavy industry – powerful polishing of thick rust, old heavy paint, welding slag and large weld grooves.
• Non-ferrous metals, stone and fiberglass – coarse grinding and rapid shaping.
• Shipbuilding, construction machinery and mining equipment – large-area rust removal and surface pretreatment, laying a solid foundation for subsequent spraying.
• High-power hand-held angle grinders – high-cutting coarse machining processes.

Why Is F14 Black Silicon Carbide Ideal as a Raw Material for Sanding Discs?

High Hardness and Excellent Self-Sharpening Performance

Its sharp crystals fracture continuously during grinding to generate new cutting edges, maintaining stable grinding capacity without passivation or slipping. Its coarse grinding efficiency is much higher than ordinary brown corundum abrasives.

Low Cutting Resistance and Labor-Saving Operation

The sharp grain edges bite into materials quickly, removing more metal under the same pressure, effectively reducing workers’ operating load and improving overall processing efficiency.

Outstanding Heat Resistance and Thermal Conductivity

It can quickly dissipate frictional heat generated during grinding, avoiding workpiece blackening and annealing discoloration, and slowing down thermal loss and service failure of sand discs.

Strong Chemical Stability

Resistant to acid and alkali corrosion, it rarely reacts with carbon steel, cast iron, non-ferrous metals, fiberglass and stone, realizing wide adaptability for different processing materials.

Reasonable Grain Toughness

F14 coarse grains have balanced fracture toughness, ensuring strong cutting force while avoiding overall crushing, perfectly combining powerful grinding performance and long service life.

Uniform and Controllable Grinding Texture

It forms a regular rough base after coarse grinding, which significantly enhances the adhesion of subsequent paint and anti-corrosion coatings.
