Grades WC (Tungsten Carbide) „Igetalloy“ Igetalloy carbides have a solid history and a big variety of grades to suit many different applications. They are widely used and appreciated for their superior performance. The Igetalloy line-up consists of carbide cutting tools that are available in a variety of different structures and compositions, each differing in terms of WC grain size and containing varying amounts of CO binder and TiC, TaC, and other double carbide components. The wide selection enables excellent wear resistance and toughness with a variety of work materials and cutting conditions. l For Steel l For Stainless Steel l For Cast Iron A30N U2 H10E Characteristic Values Application Grade Hardness(HRA) TRS Young's Modulus Thermal Conductivity Compressive Strength Linear-Thermal Expansion(GPa)(GPa)(W/m·°C)(GPa)Coefficient (X 10-6/°C) ST10P 92,1 1,9 470 25 4,9 6,2 ST20E 91,8 1,9 550 42 4,8 5,2 A30 91,3 2,1 520 — — 5,2 A30N 91,2 2,2 520 — — — ST40E 90,4 2,6 — 75 — — U10E 92,4 1,8 460 — 5,9 — EH510 92,6 2,6 — — — — U2 91,5 2,2 — 88 — — EH520 91,7 3,0 — — — — A30 91,3 2,1 520 — — 5,2 A30N 91,0 2,4 — — — — BL130 94,3 2,9 — — — — H2 93,2 1,8 600 105 6,1 4,4 H1 92,9 2,1 650 109 6,1 4,7 EH10 92,4 3,4 640 105 — 4,5 EH510 92,6 2,6 — — — — H10E 92,3 2,0 — 67 — — EH20 91,3 3,5 620 105 — 4,5 EH520 91,7 3,0 — — — — G10E 91,1 2,2 620 105 5,7 — H1 92,9 2,1 650 109 6,1 4,7 EH510 92,6 2,6 — — — — EH520 91,7 3,0 — — — — B6
