Frequently Asked Questions

What are bimetallic wear parts?

Bimetallic wear parts combine a high-hardness white iron surface (63HRC/700BHN) with a tough mild steel base through vacuum brazing. This provides excellent wear resistance while maintaining weldability and impact strength.

What industries use your products?

Our wear parts are widely used in mining, quarrying, cement, recycling, power generation, and any heavy industry involving abrasive material handling.

Can you produce custom designs?

Yes. We have toolings for over 400 shapes and can develop custom molds based on customer drawings or samples.

What is the advantage of vacuum brazing?

Vacuum brazing ensures a clean, strong metallurgical bond between the white iron and steel substrate without oxidation, resulting in superior durability and reliability.

Do you offer samples?

Yes, we can provide samples for evaluation. Contact us directly to request specific parts.
