What Are Bimetallic Chocky Bars?

Bimetallic chocky bars are wear-resistant plates or strips made from two different metals. Typically, they feature a layer of ultra-hard white iron, with hardness levels around 63-65 HRC | metallurgically bonded to a ductile mild steel backing. This unique composite structure offers the best of both worlds: exceptional surface wear resistance and underlying impact toughness.

For example, the CB25 Notched Chocky Bar (25mm x 240mm) or the CB40 Notched Chocky Bar (40mm x 240mm) from AU Buckets are manufactured with this bimetallic design, featuring pre-formed notches for easy cutting and installation.

Why Use Bimetallic Wear Products?

• Superior Abrasion Resistance: The white iron surface combats grinding and scraping from rocks, debris, and raw materials so equipment lasts longer.
• Impact Toughness: The mild steel backing absorbs shocks and reduces cracking, preventing sudden failures.
• Easy Customisation: Notched designs allow onsite cutting for shapes that perfectly fit your application.
• Simple Installation: Can be welded directly onto bucket lips, chutes, conveyors, crushers, and more. Pre-weld preparation is straightforward, and detailed weld instructions can be provided on request to ensure optimal performance and longevity.
• Reduced Downtime & Maintenance: Longer-lasting wear parts mean fewer replacements, less downtime, and more productivity.

Common Applications of Bimetallic Chocky Bars

Bimetallic wear parts are widely used in industries exposed to abrasive materials and harsh conditions, including:

• Mining and Quarrying: Bucket lips, loader and excavator wear protection, crusher liners.
• Earthmoving: High-wear areas on excavator buckets and loaders.
• Material Handling: Chutes, hoppers, conveyor systems that require abrasion resistance.
• Construction: Crushing and screening equipment needing durable liners and guards.
• Recycling: Hammer tips and wear plates for processing equipment.
