研制开发了一种既锋利又耐磨的新型复合基金刚石圆锯片，其胎体主要成分为６６３（锡青铜）－Ｗ（ＷＣ）－Ｎｉ－Ｆｅ－Ｃｏ。实际生产结果表明，该锯片切削花岗岩的锋利度比传统的Ｃｏ基、Ｆｅ基提高了４０％～５０％；使用寿命比Ｃｏ基提高了６％～１０％，比Ｆｅ基提高了１４％～１８％；而生产成本是Ｃｏ基的５０％左右，与Ｆｅ基相当。板材生产的综合效益提高了２０％～３０％。
Developed a new type of composite diamond saw blade that is both sharp and wear-resistant. The main component of the matrix is 663 (tin bronze) -W (WC) -Ni-Fe-Co. The actual production results show that the saw blade cutting granite sharp than the traditional Co-based, Fe-based increased by 40% to 50%; life than Co-based increased 6% to 10%, 14% 18%; while the production cost is about 50% of Co base, which is equivalent to Fe base. Comprehensive benefits of sheet metal production increased by 20% to 30%.
