Wear Parts & Custom Castings
Eight part families, cast and machined in Kalulushi. Every family page carries drawing references, material options, hardness and a downloadable spec sheet. If your part isn’t listed, we cast to drawing or to sample.
DIRECT ANSWER
What are crusher wear parts?
Crusher wear parts are the replaceable steel components that take the impact and abrasion inside crushing and grinding equipment: jaw plates, blow bars, cone liners, mill liners and grinding media. They are consumables, sized to the machine and specified by alloy and hardness.

CHOOSING A MATERIAL
Which alloy suits which duty: read across, then talk to us about your feed and crusher setting.
| Material | Typical Hardness | Work-Hardens | Best For | Avoid When |
|---|---|---|---|---|
| Mn13 (austenitic manganese) | 200 BHN as-cast, to 500+ in service | Yes, strongly | Jaw plates, cone liners, high-impact crushing | Low-impact duty: it never hardens |
| Mn18 | 220 BHN as-cast, higher work-hardened peak | Yes | Heavy primary crushing, abrasive hard rock | Cost-sensitive light duty |
| Cr-Mo alloy steel | 320–400 BHN | No | Mill liners, hammers, mixed impact/abrasion | Extreme impact loading |
| High-chrome iron | 600–700 BHN | No | Sliding abrasion, pump parts, fine crushing | Impact duty: it is brittle |
Hardness figures are general metallurgical reference values, not batch-specific guarantees. Confirm grade selection with our team for your application.
