Premium Bimetallic Chocky Wear Bars

Product Name: High-Chrome Bimetallic Chocky Wear Bars for Excavator Bucket & Chute Protection

Description:

Instantly eliminate catastrophic wear hot-spots with our premium Bimetallic Chocky Wear Bars. Universally known as the “first-aid armor” for heavy industrial equipment, chocky bars feature a unique layout that mimics a chocolate bar, allowing them to be easily cut and bent to fit both flat and heavily contoured surfaces.

Our chocky bars feature a premium Metallurgical Bond combining two distinct layers: a super-hard, high-chromium white iron wear face ($\ge 15\%\text{ Cr}$) bonded flawlessly to a weldable mild steel backing plate. This combination delivers diamond-grade resistance against extreme sliding abrasion from rock, sand, ore, and slag, while providing a tough, shatter-proof backing that can be welded with standard welding rods.

Why Our Chocky Bars Deliver Unbeatable Field Value:

• Extreme Hardness ($\ge \text{HRC 63 / HBW 700}$): The high-density chromium carbide microstructure resists deep gouging and scoring far better than traditional AR400/500 quenched steel plates.

• Easy Formability (Notched Design): The deep molded V-grooves allow you to easily crack the bar into smaller segments or bend it around tight radiuses (like bucket shanks or concave hopper liners) without damaging the wear layer.

• Cost-Efficient “Spot” Protection: No need to replace entire massive liner sheets; simply weld our compact chocky bars exactly where the high-wear streams attack.

Key Technical Highlights:

• Perfect Shear Bond Strength: Our proprietary vacuum-fusion bonding process guarantees a shear strength exceeding $250\text{ MPa}$, ensuring the high-chrome layer will never delaminate or pop off under heavy material shock.

• Versatile Applications: Perfect for shielding excavator and loader bucket liners, dragline buckets, conveyor transfer chutes, rock hoppers, and dredging pump casings.

• Broad Size Range: Available in standard industry profiles (CB25, CB40, CB50, CB65, CB90, CB100, and CB130).
