What colour is the copper wire (copper nickel alloy)? Please speak more in detail, thank you
. Ingredients: nickel content 40%, manganese less than 1%, copper margin. Properties: 0.48 ohm m, density 8.9g/cm3, melting point 1280 DEG C, maximum temperature 480 DEG C. Features: good processability and good weldability.
Konstantan: grade 6J40 belongs to a class of copper based alloy resistance. The main role in instrumentation, electronic and electronic components in industrial equipment.
Novokostant: grade 6J11 belongs to resistance alloy. A similar 6J40 constantan resistivity compared mainly in the industry, instead of 6J40. resistance constantan has the advantages of low cost. Disadvantages: no 6J40 constantan resistance temperature coefficient stability, welding general. Color: Black
