Products Description
Delivering an ideal synthesis of structural rigidity and surface anti-friction performance, our Copper Clad Steel Bimetal Sheet fuses a tin- or lead-bronze alloy layer to a low-carbon steel core. We manufacture this high-formability Copper Clad Steel Bimetal Sheet for OEMs fabricating bimetallic sleeve bearings, automotive thrust washers, machine tool sliding ways, and marine wear components. With shear strength exceeding 150 MPa and exceptional sheet flatness of ≤0.08 mm/m, our Copper Clad Steel Bimetal Sheet withstands high-speed blanking, forming, and precision grinding, serving as a reliable, direct substitute for imported bimetallic stock at substantial cost savings.
Application Scenarios
- Primary raw material for rolled bimetallic sleeve bearings and wrapped bushings.
- Production of wear-resistant guide strips for industrial molds, machine tools, and presses.
- Anti-friction structural components in commercial marine systems and metallurgical equipment.

FAQ
Q: Can this clad sheet be rolled directly into cylindrical bushings?
A: Yes. The metallurgical bond withstands roll-forming into cylindrical bushings without interfacial splitting, maintaining tight concentricity and roundness.
Q: What payment terms and currencies do you accept for raw plate orders?
A: We accept USD payments under EXW or FOB terms, operating with a 50% deposit before production scheduling and 50% balance before factory dispatch.
