Sparking plug electrode nickel alloy
Nickel alloy: NMn2-1.8-1.8, NMn4-1, NCi-5-3-1.8, NCr2-1-0.5,
NCr1.5-1.5-0.5
NiMnSiCr alloy wire-(NMn2-1.8-1.8), has good refractory, oxidation
resistance, physical and mechanical properties and process ability.
It is used as the spark plug central electrode, which can perform
both good electrical conductivity and heat conductivity.
NiMnSi alloy wire (NMn4-1), has corrosion resistance of high
temperature gas, anti-ablation, good heat conductivity, with
appropriate strength and hardness, it can be processed into flat
wire in different sizes, used as the side electrode of the spark
plug.
NiCrMnSi alloy (NCr5-3-1.8), has good refractory, oxidation
resistance, physical and mechanical properties and process ability.
It is used as the spark plug central electrode.
Nickel Alloy Wires NCr3-5-1.5 For Sparking Plug Electrode
Application:
As the central electrode and side electrode of Automobile &
motorcycle spark plug.
