When working with thin aluminum sheets, it's important to handle them carefully to prevent denting or bending. Use gloves to avoid oils and moisture from hands that can cause corrosion. Ensure proper ventilation when cutting or shaping to avoid inhaling aluminum dust. Use sharp tools to minimize the risk of tearing or marring the surface. Also, consider the specific alloy's properties, as different aluminum alloys have varying strengths and malleabilities. Always follow safety guidelines and use appropriate protective equipment.
