Buy carbide alloy material to be appropriate for the procurement in accordance with carbide work
1, WC-Co (tungsten drill) alloys:
From tungsten carbide and cobalt. Sometimes the cutting tool (sometimes also drawing die) in other carbide added
2% or less (tantalum carbide, niobium carbide, vanadium carbide, etc.) as an additive.
High cobalt: 20-30% cobalt: 10-15% lower cobalt: 3-8%
2, WC-TiC-Co (tungsten, iron, cobalt) alloys
Low Titanium: 4-6% TiC, 9-15% Co,
In titanium alloy: 10-20% TiC, 6-8% Co,
High Titanium: 25-40% TiC, 4-6% Co
3, WC-TiC-TaC (NbC) -Co alloys
WC-TiC-Co alloys have better oxidation resistance, but also has good thermal shock resistance interference, which
often have a higher tool life.
TiC: 5 a 15%, TaC (NbC): 2-10%, Co5-15%, the remainder of WC.
4, steel bonded carbide
From tungsten carbide or titanium carbide and carbon steel or alloy composition
5, titanium carbide-based alloys
Carbon ratio of titanium, nickel and molybdenum metal or carbide two molybdenum (Mo2C) components. The total
content of nickel and molybdenum is typically 20-30%.
