Tinned brass wire is a conductive material with a layer of tin plated on the surface of the brass wire. It combines the advantages of brass and tin and is widely used in situations where excellent conductivity, corrosion resistance and weldability are required.

 

Material composition

Brass substrate

Brass is an alloy synthesized from copper and zinc, which has high conductivity and mechanical strength.

Depending on the zinc content, brass can show different hardness and ductility.

 

Surface tinning

A layer of tin is plated on the surface of brass, usually by electroplating or hot-dip plating.

Tin has good oxidation resistance and can protect the brass substrate from corrosion and oxidation.

 

Main features

Excellent corrosion resistance

The tin layer effectively prevents brass from contacting with air or moisture, extending its service life.

 

Good weldability

The tin layer improves the solderability of the material, making it suitable for electronic wiring and electrical connections.

 

High conductivity

Brass as a conductive substrate, coupled with the anti-oxidation protection of tin, makes tinned brass wire perform well in electrical properties.

Mechanical strength

Brass itself has high tensile strength and toughness while maintaining a certain degree of ductility.

Smooth surface

The tinned layer makes the surface of the brass wire smoother and brighter, suitable for high-quality electrical connection occasions.

Application areas
Electronic and electrical industries

Used in the manufacture of wires, cables, leads, terminals, etc.
Used as a conductor in precision circuits to reduce contact resistance.

Communications industry

Used in data transmission lines and communication cables to ensure high-quality signal transmission.

Automotive industry

As a conductive connector in automotive wiring harnesses, it provides stable electrical performance.

Aerospace field

In environments with high reliability requirements, tinned brass wire is widely used due to its corrosion resistance and conductivity.

Crafts and jewelry production

Due to its bright appearance, it is also used to make crafts, decorative materials, etc.
