Supplier KMZ offers to buy a sheet, a ribbon of the alloy Constantan Mnmc40−1.5, Mnmc43−1.5 at economical price. The provider ensures timely delivery of products at any address specified by the consumer.

Technical characteristics of alloy

Constantan is an alloy with moderate resistivity and low temperature coefficient of resistance with a flat-exponential resistance / temperature over a wider range than manganin. Constantan also demonstrates better corrosion resistance than manganini. Its use is usually limited to AC circuits.

Electrical properties

  • Electric resistance (μω/cm) 52,0;
  • Temperature coefficient (K-1) +/- 0,00002;

Mechanical properties

  • Relative tensile elongation (%) — 45;
  • Hardness Brinell N. V. — 100…300;
  • The modulus of elasticity (GPA) — 162
  • The limit of the tensile strength (MPa) at 400 590;

Physical properties

  • Density (kg/ m3) — 8900;
  • Melting point (°C) 1300 1225…;
