TOYIROK-TOYIROK

Ultrafine grained cemented carbide rods selection of the most high quality raw materials, through the HIP and CIP process, follow the most stringent testing standards, to ensure that each one has no porosity, effectively eliminate internal stress, high hardness, corrosion resistance, high impact toughness and high fatigue strength, etc..

Widely used for hardened steel, high temperature aluminum alloy, titanium alloy CNC milling cutter, hole processing hard alloy blade, chemical fibre cutter, high speed IC and EI level in punching die, field.etc..

Cemented carbide rods divided into the cutting tool rod and the die rod.The concrete material and performance are shown in the following table:

Tungsten Steel	Cobalt Content	Hardness HRA	Granularity	Performance	Use to
FB-30	10%	91.5-92.0	Fine particles	Mainly used for cutting tools, the hardness and strength of good performance, widely used in the hardness of 55 degrees below the steel cutting	Common tool bar
FZ-40	12%	92.5-93.0	Ultrafine particles	High - grade tool bar cutting material, cutting performance is good, suitable for processing the hardness of 60 degrees above the steel	High - grade tool bar
NC-50	13%	88.5	Fine particles	To ordinary stamping, with high toughness, hardness is moderate	Punch / punching / extrusion / plastic
NC-60	15%	90	Fine particles	The toughness and the strength performance is very good, the strength is higher than that of NC-50, which has the wear resistance, not easy to crack characteristics	High speed stamping, motor, motor, LED industry
