Accumulative Roll Bonding (ARB) for Multi-Metal Sheets Fabrication

Conventional single material metallic sheet cannot meet the growing requirement of high strength, good anti-corrosion and thermal conductivity at the same time. Moreover, the manufacturing process of conventional composite materials fabrication process is relatively more complex and environmentally harmful.

• The ARB process can form strong mechanical bonds among aluminum, copper, steel and other metal materials through severe plastic deformation (SPD), to produce multi-layer and sheet metal parts of multiple layers and materials.
• The composite metal sheet has the advantages of high-strength, lightweight and corrosion resistant, and also has thermal conductivity.

• Improve the versatility and work performance of metal fittings as critical components, which can enhance safety and save energy.
• New high-performance materials can enhance product value, such as increased strength, lightweight, thermal conductivity and corrosion resistance.
• The fabrication process is under atmospheric environment without causing air, liquid or solid pollution.

• Produce composite alloy sheets with the combination of two or more metals, such as steel-aluminium, steel-copper, magesium-copper, and steel-aluminium-copper.
• Fabricate stamping products with different combinations of enhanced functional requirements, such as high-strength, lightweight, good heat dissipation, excellent electrical conductivity, and magnetic shielding.
