Press Brake Tonnage Calculator
Inputs (air bending)
Material (tensile strength)
Mild steel (450 N/mm²)
Stainless 304 (620)
Aluminum 5052 (230)
Brass (350)
Copper (300)
HSLA / Hardox (700)
Material Thickness S (mm)
Bend Length L (mm)
Die Opening V (mm)
Rule of thumb: V ≈ 8× thickness for thin material
