ASSAB LG-5 a carbide LG-5 Assab Assab tungsten steel LG-5 size: particles 1-3 (um) cobalt content: 12.5 (%) Density: 14.2 (g/cm3) Hardness: 88 ( HRA) Flexural strength: 380 (kg/mm2) Applications: 1. continuous die 2. lining cylinder 3. terminal 4. deep draw molding 4. cutter, die 5. planted scissors, motor silicon copper. Carbide matrix consists of two parts: one is the hardening phase; other part is a metal bond. Periodic table of the hardening phase is the transition metal carbides, such as tungsten carbide, titanium carbide, tantalum, their high hardness, melting point above 2000 ℃, and some even more than 4000 ℃. In addition, transition metal nitrides, borides, silicides have similar characteristics, but also can act in the cemented carbide hardening phase. Determine the presence of the hardening phase of the alloy with high hardness and wear resistance.
