Silver Alloy Wires

Product overview:

Our company can supply a variety of silver wires made of Pure silver, FAg, AgCdO, AgNi, AgCu, AgSnO2, AgSnO2In2O3, AgZnO, etc.

(A)Pure Silver wires:

1.Physical Property:

Material	Composition	Density(g/cm3)	Resistivity(μΩ.cm)	Hardness(MPa)
Ag	>99.95	>10.49	<1.6	>600

2.Features:

(1) Pure silver has extremely high electrical conductivity

(2) Very low contact resistance

(3) Easy to solder

(4) It is easy to produce, so silver is an ideal contact material

(5) It is one of the most widely used materials in small capacity and voltage

(B)AgCdO Wires:

1.Physical Property:

Material	Composition		Density g/cm3	Resistivity μΩ.cm	Hardness HV(MPa)
	Ag	CdO
AgCdO10	90	10	>10.05	<2.25	>750
AgCdO12	88	12	>10.0	<2.3	>800
AgCdO13	87	13	>9.95	<2.35	>800
AgCdO15	85	15	>9.90	<2.4	>800

2.Features:

(1) AgCdO is a kind of most important contact material among silver metal-oxide materials, and it is widely used for low-voltage devices

(2) When the temperature is higher than 900oC, CdO is sublimated and the contact surface is cooled down in order to reduce and even extinguish the arc energy. This method can increase the resistance against welding

(3) Contact materials produced by powder sintering-extruding methods have higher density and lower resistance rate

(4) It also has higher welding resistance and uniform arc erosion Inner

(C)AgNi Wires:

1.Physical Property:

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

 2.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
