- When cutting aluminum with a hacksaw, choose the right blade12345:
- Bimetal hacksaw blades are the best type for cutting aluminum. They are made from two different types of metal (usually high-speed steel and spring steel) which makes them flexible and resistant to wear and tear1.
- Choose a blade with fewer teeth per inch (TPI), as aluminum shavings tend to clog up hacksaw blades. Blades with 18, 24, and 32 TPI are suitable for most applications2.
- For cutting light metals like aluminum, a higher TPI (e.g. 32 TPI) provides a smoother cut3.
- High carbon steel blades are also suitable for cutting aluminum and other non-ferrous metals4.
