Product Description

Nickel alloy wires (NiCrofor 7618 ) NMn4-1 for sparking plug electrode 


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.
 
Application:
As the central electrode and side electrode of Automobile & motorcycle spark plug.
