China Top Quality Hard Alloy Dies in Different Types, Find details about China Cemented Carbide Die, Carbide Dies from Top Quality Hard Alloy Dies in Different Types
Application Of Hard Alloy Drawing dies: Carbide dies are frequently and successfully used in wire drawing (round & shaped), bunching, stranding, guiding, and split die applications. Typically tungstencarbide dies are used for manufacturing wire or rod, generally in highly abrasive and high carbon material areas where PCD dies are not cost effective.
How to select the carbide wire drawing dies:When selecting wire drawing dies, wire material and drawing parameters are important specifications to consider. Typically, wire materials include:copper,stainless steel,aluminum alloy steel,galvanized high-carbon steel,gold,silver,stainless steel,low-carbon steel, molybdenum, nickel.
Drawing parameters include measurements such as inlet diameter, bell radius, entrance angle, approach angle, bearing, and back relief. Elongation, the ratio of length after drawing to the length prior to drawing, is also an important consideration when choosing wire drawing dies.
Main types of hard alloy drawing dies:
Grade | Density(g/cm3) | Hardness (HRA) | Bending Strength(N/mm2) | Grain Size(μm) | Applications |
YG8 | 14.8 | 90 | 2400 | Medium | Good balance between wear resistance and toughness, suitable for making drawing die and other dies in different sizes. |
YG11 | 14.45 | 88.5 | 2900 | Meidum | Good balance between wear resistance and toughness, suitable for making medium and large sized drawing dies. |
YG15 | 14 | 87 | 3000 | Meidum | Suitable for making steel pipes, steel rods under high stress & high Compression.Also suitable for making punching dies under heavy impact working condition. |
YG20 | 13.6 | 85 | 3200 | Meidum | Suitable for making punching dies, like bolts and nuts. |
YG20C | 13.6 | 83.5 | 3500 | coarse | Suitable for making punching dies like watch parts, steel balls and some forging dies |
ES40CC | 13.2 | 81 | 3800 | Ultra-coarse | Excellent impact resistance and good heat fatigue performance, suitable making cold heading die, cold punching die, hot forging die, hot stamping die. |
