Technical Specifications for Aluminum Profile Bending Radius Calculator (6060, 6061, 6063 Industrial Standard): This calculator provides multi-dimensional calculation results for the minimum bending radius of extruded aluminum profiles for windows, doors, and curtain walls (stretch bending and roll bending processes), encompassing three key data dimensions:

Theoretical Calculated Value

• Based on material plasticity mechanics theory (stress-strain relationship of 6060, 6061, 6063 aluminum alloy)
• Utilizes a nonlinear K-factor model, incorporating a material thickness compensation coefficient (Width/50)^0.15
• Hard Way calculation introduces a dynamic multiplier algorithm (6.0-9.0x nonlinear gradient)

BIT Engineering Recommended Value

• Applies a safety factor (0.75-0.85) to the theoretical value
• Incorporates BIT’s years of profile processing experience (width-segmented compensation mechanism)
• Specifically adds a 25% safety margin for profiles ≥60mm

Industry Reference Data

• Integrates European Qualicoat and Chinese GB5237 standard data
• Reflects the actual process capabilities of mainstream manufacturers
• Provides quick benchmarking references (conservative/aggressive value ranges)

Technical Features:

• Dual-algorithm system (linear compensation model for window/door profiles, dual-path Hard Way/Easy Way calculation for curtain wall profiles)
• Theoretical calculations retain a 10% process tolerance, while BIT recommended values include an additional 15-25% engineering safety margin
• Data comparison system identifies typical deviations between theoretical calculations and engineering practices (commonly seen in profiles >150mm wide)
