| KLT Carbide Co.,Ltd.
is actively engaged in the study and application of the material sciences. While improving on the materials already in use, KLT is researching and developing new types and grades of materials to meet a variety of emerging market demands. Although powder metallurgy, as a technigue of manufacturing hard materials has been around a long time, it must be precisely controlled and performed to ensure the highest standards of quality we expect of our cemented carbide products.
