uèir strì manganese airson co-phàirtean dealain is dealanach
Uèir manganinna alloy copar-manganese-nickel (CuMnNi alloy) airson a chleachdadh aig teòthachd an t-seòmair.Tha an alloy air a chomharrachadh le feachd electromotive teirmeach glè ìosal (emf) an taca ri copar.
Mar as trice bithear a’ cleachdadh uèir manganin airson a bhith a’ saothrachadh inbhean strì, resistors lot uèir mionaideach, potentiometers, shunts agus co-phàirtean dealain is dealanach eile.
Feartan dealain
- Co-èifeachd teòthachd: 1.5 × 10-5K-1
Feartan meacanaigeach
- Modal elasticity: 124–159 GPa
- Teòthachd cleachdaidh as àirde san adhar: 300 ° C
