Figure 1. Black steel jade has obvious transition phase in the iron matrix, which is an advantage that other corundum materials do not have.

Figure 2. Non-corner flash-like fractures, showing the characteristics of flexible abrasives.

Figure 3. SEM morphology of black steel jade raw material, with obvious conchoidal fracture and high fracture toughness.

Figure 4. The size of the Al203 knot that plays the main role of grinding is about 10 μm-100+ um, and it is surrounded and connected by the low-strength Si02 knot, which is very similar to the structure of the stacked abrasive.

Product Features

High cost performance │

The use cost is much lower than other abrasives with comparable performance.

High Quality │

During processing, the surface of the workpiece has less heat accumulation and is not easy to burn. The hardness is moderate, the cut finish of the product is high, and the discoloration is very slight.

Efficient │

Strong cutting force and self-sharpening can improve cutting efficiency.

Environmental │

Comprehensive utilization of waste materials, melting method crystallization, no harmful gas
