Yes, you can cut aluminum plate with a circular saw. However, it’s essential to use the appropriate blade designed specifically for cutting non-ferrous metals like aluminum. A carbide-tipped saw blade with fine teeth and a high tooth count (e.g., 60 to 80 teeth) is recommended for clean and precise cuts in aluminum.

When cutting aluminum with a circular saw, follow these steps for best results:

1. Secure the material: Clamp the aluminum plate securely to a stable work surface to prevent movement during cutting.
2. Choose the right blade: Install a carbide-tipped saw blade suitable for cutting aluminum on your circular saw. Ensure the blade is properly installed and tightened according to the manufacturer’s instructions.
3. Set the cutting depth: Adjust the cutting depth of the circular saw to ensure it penetrates slightly beyond the thickness of the aluminum plate but not excessively.
4. Wear safety gear: Always wear appropriate safety equipment, including safety glasses, hearing protection, and gloves, to protect yourself from metal chips and debris.
5. Cut with care: Start the saw and guide it steadily along the intended cutting line at a consistent speed. Avoid forcing the saw through the material to prevent binding or kickback. Let the saw and blade do the work.
6. Cooling: Aluminum can generate heat during cutting. Periodically stop cutting to allow the material and blade to cool down, especially during prolonged cutting sessions.

By following these guidelines and using the correct blade and technique, you can achieve clean and accurate cuts when cutting aluminum plate with a circular saw.
