Materials for Mining Components
| Material | Hardness | Applications |
|---|---|---|
| Bisalloy | 450–550 HV | Wear plates, liners, high-wear components — excellent hardness while machinable |
| Hardox | 450–550 HV | Structural wear-resistant components, crusher parts, screening equipment |
| 4140 Steel | 250–350 HV | Shafts, pins, fasteners — excellent machinability and strength |
| 4340 Steel | 300–400 HV | Heavy-duty shafts and load-bearing components — higher strength than 4140 |
| 316L Stainless | 200–250 HV | Corrosion-resistant valves, fittings, and wet-environment components |
| Bronze & Brass | 150–200 HV | Bushings, sliding surfaces, bearing components — low friction |

Mining Components FAQ
What materials are best for high-wear mining applications?
Bisalloy and Hardox are the industry standards for mining wear parts — they offer exceptional hardness (450–550 HV) while remaining machinable. 4140 and 4340 steel are used for load-bearing components like shafts and fasteners. 316 stainless is essential for components exposed to corrosive slurries or wet environments. Polyurethane and UHMWPE are increasingly used for non-metallic wear liners to reduce maintenance costs. Material selection depends on the specific wear environment — contact us to discuss your application.
Can you manufacture replacement parts for obsolete equipment?
Yes — this is a core service for mining operations. We reverse engineer obsolete components from part samples or hand sketches. If you have the original part, we can reproduce it exactly. For engineering requirements we cannot measure, we work with you to define functional specifications that match the original performance.
What is the typical lead time for mining components?
For standard CNC machined mining parts: 7–14 business days depending on material availability and complexity. For emergency breakdown manufacturing, we offer expedited delivery (2–3 business days) for critical items. Contact us immediately with your timeline — mining downtime is expensive and we prioritise urgent orders.
Do you offer emergency breakdown manufacturing?
Yes. Mining equipment breakdowns require rapid response. We maintain relationships with suppliers of critical materials (Bisalloy, Hardox, stainless steel) and can manufacture emergency replacement parts within 24–48 hours. Call us immediately if you need an urgent part — we will advise feasibility and expedited pricing.
Can you machine hardened materials like Bisalloy?
Yes. We specialize in machining hardened materials — Bisalloy, Hardox, 4140, and high-carbon steels. Our CNC machines are equipped with carbide tooling and capable of maintaining tight tolerances on hardened parts. We can machine through-hardened stock or harden-after-machining as required by your design.
What tolerances can you hold on mining components?
For non-hardened mining parts: standard ±0.05mm. For critical features: ±0.01–0.02mm. Hardened materials are typically less precise due to heat distortion, but we hold ±0.05mm routinely on Bisalloy and similar steels. For bearing surfaces or other precision-critical features, discuss tolerance requirements during your quote — CMM inspection is available.
