Tungsten Carbide Strips
Carbide strip is one of many tungsten carbide materials, which is named for its rectangular plate. It is mainly made of WC tungsten carbide and co cobalt powder mixed by metallurgical methods through pulverization, ball milling, pressing and sintering. The component contents of WC and CO in cemented carbide strips for different purposes are different, and the application range is very wide.
We provide cemented carbide strip, It has excellent characteristics of excellent rigidity, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid resistance, alkali resistance, high-temperature oxidation), low impact toughness, low expansion coefficient, and similar heat conduction and conductivity with iron and its alloys. It has a brand that is especially suitable for manufacturing reversible woodworking blades. It has very good performance in quality, such as wear resistance (not needing frequent grinding), impact resistance and long service life. It greatly improves the production efficiency of customers and has been recognized by many customers.
