AgNi Contact:

Features:

(1) AgNi contact material contains 10% to 40% Ni

(2) Produced by powder metallurgical production, with low and stable contact resistance, high hardness and mechanical strength

(3) Material transfer in case of DC is very low

(4) High electrical and thermal conductivity

(5) With very low arc erosion. On making higher current, normally asymmetric pairs with Ag contact materials are applied

(6) Wire of solid and composite rivets produced by powder sintering-extruding methods

AgNi physical property:

Material	Composition		Density g/cm³	Resistivity μΩ.cm	Hardness HV(MPa)

AgNi₁₀	90	10	>10.25	<2.10	>800
Ag Ni₂₀	80	20	>10.25	<2.30	>850
Ag Ni₃₀	70	30	>9.7	<2.70	>850
Ag Ni₄₀	60	40	>9.5	<3.40	>850

Samples: Our sample is free, but the customer has to pay the tooling charge if the quantity is too large. Meanwhile the express fee should be paid by the buyers. (But we may negotiate that later)
