[0002] With the acceleration of industrialization, breakthroughs in material processing and preparation technology continue to emerge, driving the application of bra blocks in many industrial fields, especially in the polishing process of high-density stone such as quartz stone. Quartz stone is a stone with high hardness and density, with a quartz content of more than 80%. Due to its high-density characteristics, it exhibits excellent wear resistance, corrosion resistance, and stain resistance, and does not easily oxidize and discolor.

[0003] However, due to the high density and high quartz content of quartz stone, existing metal bra blocks often have insufficient sharpness during polishing, resulting in poor polishing results. Therefore, there is an urgent need for a metal bra block product with high sharpness and good versatility.

[0004] To meet the above needs, the stone processing industry needs a new type of metal bra block product that has high sharpness, can be widely used in various stone processing scenarios, and has good versatility. In addition, a low-cost metal matrix formula is also needed to reduce product manufacturing costs and meet increasingly stringent environmental protection requirements. Market demand trends drive the industry to develop higher quality, higher efficiency, and lower cost.

[0005] Although the preparation formula and method of wear-resistant bra blocks have developed, the current formula and method have complex preparation processes, high costs, and unsatisfactory results.
