## Thermal Growth Description
Thermal Growth is a fast and accurate thermal expansion calculator for machinists, toolmakers, CNC programmers and inspectors.

Temperature changes affect dimensional accuracy. Thermal Growth computes the precise size adjustment required to hit your target dimension at the reference temperature.

Features

• Calculate thermal expansion offsets using standard engineering formulas
• Supports steels, aluminium alloys, titanium, copper, brass, tool steels and polymers
• Works across –273°C to 2500 °C
• Adjustable reference temperature (default 20 °C)
• Supports metric (mm/°C) and imperial (inch/°F)
• Large, clear result with full calculation breakdown
• Fully offline — ideal for workshop or inspection environments
• Clean, workshop-friendly interface with dark and light mode
• Request new materials directly from the app

Material Database Includes

• Aluminium alloys (2014, 2024, 6061, 6082, 7075)
• Non-ferrous metals (Copper, Brass CW505L, Phosphor Bronze, Monel, Nickel, Inconel)
• Tool steels (A2, D2, P20)
• Polymers (Acetal/Delrin, PEEK, ABS and filled grades)
• Additional materials added regularly

Designed for Machinists

Whether turning, grinding, milling or inspecting tight-tolerance components, Thermal Growth gives you the correct temperature-compensated dimension instantly.
