Product Detail1

Shanghai Metal Corporation is a leading Silver Plated Copper Wire manufacturer and supplier.

The silver-plated copper wire is silver-plated or drawn on high-quality oxygen-free copper, and has excellent electrical conductivity, thermal conductivity, corrosion resistance and high-temperature oxidation resistance. Silver-plated copper wire is widely used in electronics, communications, aerospace, military and other fields to reduce the contact resistance of metal surfaces and improve soldering performance. Silver has high chemical stability, can resist alkali and some organic acids, in general air. Does not interact with oxygen.

If you want to know more about our silver-plated copper wire or other copper alloy wire price please feel free to contact us, we will reply you within 24 hours.

1) Diameter: 0.02mm~2.6mm

2) Resistivity:Ω.mm2/m,at 20 ℃, Coefficient of resistance

3) Coating: 1.The plating of the conductor should be continuously plated on surface firmly, after testing no black shall be on the sample’s surface.

2.The conductor should be smooth and continuous on the surface, free from some injurious defects such as grains,burr,mechanical damage and so on.

1) Silver Coating:uniform,continous,good adhensiion

2) Surface Finish :The surface of silver coated copper wire is bright,continues and free from harmful defects such as silver grains,burr,mechanical damage

0.10≤ d ＜0.230 196 15

0.23≤ d ＜0.500 196 20

0.50≤ d ≤2.600 196 25

Coating of Silver Plated Copper Wire:

1.The plating of the conductor should be continuously plated on surface firmly, after testing no black shall be on the sample’s surface.

2.The conductor should be smooth and continuous on the surface, free from some injurious defects such as grains,burr,mechanical damage and so on.

Testing of Silver Plated Copper Wire:

1.All products must be tested qualified before deliver, we have three processes for testing:IQC-IPQC-FQC, the quality certification report should be delivery together with each batch

2.Products testing rule should be as follows:

No ITEM Testing Method

1 Silver Percentage & Coating Thickness Coating Thickness Tester

2 Diameter & Tolerance Micrometer

3 Appearance Nominal Visual Test

4 Continuity of plating GB/T4909.9

5 Mechanical Property GB/T4909.3

6 Resistivity GB/T3048.2

Package of Silver Plated Copper Wire:

1.Finished products should be wrapped by brown paper & plastic warp then put in carton

2.Silver coated soft copper wire should be wond on reel. There should be some distance between products surface and the edge of reel

3.Delivery according to the agreement of the two sides

Q1.What is the MOQ and production lead time?

A: The minimum order quantity is typically 100kg, depending on the specific wire diameter. Standard production lead time is 15-25 working days after order confirmation.

Q2.What information do you need for a custom quotation?

A: Please provide the required wire diameter, silver coating thickness (or percentage), target application, estimated quantity, and preferred trade terms (e.g., FOB Shanghai).

Q3.How long does sample preparation take?

A: For standard diameters, sample preparation takes 3-7 working days. Customized coating thicknesses may require up to 10 working days.

Q4.What is the difference between silver-plated copper wire and tinned copper wire?

A: Silver-plated copper wire offers superior electrical conductivity, high-frequency signal transmission, and can withstand higher operating temperatures. Tinned copper is generally more cost-effective and focuses primarily on basic corrosion resistance and solderability.

Q5.What quality standards does your silver-plated copper wire meet?

A: Our products comply with GB/T3953 for copper wire, GB/T41354 for silver, and JB/T3135 or ASTM B298 for the finished silver-plated soft copper wire. We implement strict IQC, IPQC, and FQC testing processes.
