Technical Description
The technology relates to the production of high-strength alclad sheets by bonding pure aluminium AA1060 layers to an age-hardenable AA6061 alloy core. The prepared layers are stacked, riveted and joined through single-pass load-assisted cold roll bonding, followed by a short low-temperature heat treatment and multi-pass rolling.
Problems Addressed
- Long And Costly T6 Aging Treatment
- Bond Strength Loss During Extended Aging
- Oxidation And Eutectic Melting At High Temperature
- Limited Roll-bonding Automation
- High Alclad Production Cost
- Trade-off Between Strength And Corrosion
Tech Features
- Core & Clad Partitioning 4–6 mm core and 0.5–2 mm clad
