White fused alumina (WFA) is a high-quality synthetic abrasive material made from the fusion of high-grade industrial alumina powder in an electric arc furnace at high temperatures. It is one of the hardest abrasives available and is known for its superior performance and versatility in various abrasive applications.
White fused alumina has a white or slightly blue-grey color, and its high purity and crystal structure make it highly resistant to chemical and physical wear. It has excellent cutting properties and is ideal for use in grinding, cutting, lapping, and polishing of various materials, including metals, ceramics, glass, and plastics.
