Heavy hardfacing electrodes and gouging rods engineered to withstand brutal mineral abrasion in open-cast mines, quarries, and cement plants.
Opencast coal mining, iron ore extraction, limestone quarries, and aggregate crushing plants subject machinery to relentless metal-to-mineral abrasion coupled with shattering mechanical impact.
Magnarc hardfacing electrodes deposit complex martensitic and chromium-carbide alloy matrices that protect excavator bucket cutting edges, dragline lips, crusher hammers, and feeder chutes, multiplying equipment uptime between overhauls.
Tailored alloy overlays designed to resist severe mineral grinding, high-stress gouging abrasion, and impact.
| Equipment / Wear Part | Primary Wear Mode | Recommended Magnarc Alloy | Hardness Range | Operational Value |
|---|---|---|---|---|
| Excavator Bucket Lips & Teeth | Heavy gouging abrasion + impact | MAGNARC HARD-600 | 58 – 62 HRC | Retains sharp cutting profile against granite & ore |
| Cement Clinker & Coal Chutes | Extreme mineral erosion | MAGNARC CARBIDE-65 | 62 – 65 HRC | High-chromium carbide resists fine abrasive slurries |
| Crusher Rolls & Hammer Heads | Severe impact + compressive wear | MAGNARC HARD-350 / 600 | 350 BHN to 60 HRC | Dual-layer system (tough buffer + hard capping) |
| Track Rollers, Idlers & Shafts | Metal-to-metal friction & galling | MAGNARC HARD-250 | 220 – 260 BHN | Easily machinable to restore exact factory clearances |
| Damaged Liner Plate Replacement | On-site repair sizing & beveling | MAGNARC CUT-ARC / GOUGE | Exothermic Jet | Cuts through manganese liners without gas tanks |
