ThermoPerm (Mutemp) / UNS N03300 (Modified) / 1.3922 (Modified) / Ni30Fe

📄 Product Description: ThermoPerm & Mutemp – Precision Thermal & Structural Strips

General Characteristics

• ThermoPerm refers to bonded, multilayer alloys (e.g., TM1/Imphy R80, Dimpty R80) engineered for thermal-actuated bending. It combines metals with different coefficients of thermal expansion to create precise, temperature-responsive strips
• Mutemp (also known as 1J31 or MS‑2) is an ultra-thin precision alloy strip, cold‑rolled to extremely fine gauges (0.005–0.3 mm). It offers high strength, dimensional accuracy, and thermal and wear resistance

Applications

• ThermoPerm bimetallic strips are essential in automatic controls—thermostats, thermostatic relays, voltage regulators, diaphragm meters—where temperature-induced bending opens or closes circuits
• Mutemp/1J31 strips are ideal for precision engineering in aerospace, electronics, sensors, and transformer components, offering tight dimensional control and stability across temperature cycles

Key Features & Benefits

• ThermoPerm:
  • High reliability in thermal switching due to predictable curvature with temperature.
  • Robust performance in heating/cooling cycles.
• Mutemp:
  • Ultra-thin (5–300 µm), with excellent formability and polished surface.
  • Combines high strength, dimensional stability, and wear resistance
  • Compatible with various metallurgical standards (AISI, ASTM, DIN, JIS).

Typical Properties

✅ Summary

• Choose ThermoPerm for applications requiring temperature-actuated movement, like thermostats, valves, or thermal relays.
• Opt for Mutemp (1J31) when high-precision, ultra-thin, mechanically stable strips are essential—for instance, in aerospace, electronics, or transformer laminations.
