Technical specifications
The alloy is precision with high electrical resistance. It combines high t ° melting and considerable electrical resistance: 1.25−1.35 Ohm • mm2 / m ,. Hardness of HB 10 -1 = 180 — 250 MPa. The relatively low density (7.25 g / cm³) makes the alloy lighter than nichrome by 17%. Due to the use of inexpensive aluminum instead of nickel, the cost of production is reduced by 6 times compared with nichrome.
