Tinned high temperature and corrosion resistant wire threaded inserts

The biggest advantage of tinned steel wire thread insert is better corrosion resistance, for corrosion resistance has too high requirements, can consider tinned steel wire thread insert. Wire thread insert, also known as thread sheath, wire sleeve, is an insert developed to protect non-ferrous metal thread holes, is a new type of internal thread fastener, suitable for threaded connection, screw and fasten in the threaded hole of one of the connected parts, forming a standard internal thread, and then screw the bolt (or screw) into it. It is a spring-like internal and external thread concentric body made of cold-rolled diamond stainless steel wire. It is mainly used to strengthen and protect the internal thread of low-strength materials, eliminate thread manufacturing errors, improve connection strength, effectively reduce the effect of uneven thread acceptance and anti-shock vibration, and extend the life of thread holes.

The main functions of surface tinning include anti-corrosion, appearance, improve welding performance and electrical performance.

Anti-corrosion: tin layer can effectively prevent the surface of stainless steel from being corroded, by forming a layer of strong compounds with the surface of stainless steel, protect stainless steel from oxidation and other corrosion factors.

Beautiful: tinned stainless steel surface has a good appearance, has become an important decorative material, can improve the appearance of stainless steel.

Improved welding performance more high temperature resistance: due to the good soldering properties of tin, stainless steel surface tinning can make it more firm in the place that needs to be welded, this is of great value for the manufacture of machinery and other parts that need high temperature resistance.

Electrical properties: tinned stainless steel surface can have excellent electrical properties, makes it an important material used in the electronic industry, from electronic components to capacitors and batteries and other electronic products need to use surface tinning.

In addition, tin coating is also widely used in the electronic industry as a protective and solderable coating for electronic components, wire, printed circuit board and integrated circuit blocks because of its excellent corrosion resistance and weldability.

For steel wire threaded inserts made of 304 stainless steel, the surface treatments available are：

1. No treatment, natural surface
2. Environmentally friendly colour plating, according to customer needs can be plated in purple, green, blue, red. In industries where large quantities of threaded inserts are required, colour plated wire threaded inserts help to identify whether they are installed or not. The different colors of the wire threaded inserts are also very convenient for visual management.
3. Cadmium plating, cadmium (cd) plated steel wire threaded inserts corrosion resistance, lubrication, wear resistance, electrical conductivity, electromagnetic properties, heat resistance is stronger.
4. Silver-plated, silver-plated steel threaded bushings can be installed in a variety of shell materials, including magnesium alloys, aluminium alloys and corrosion and heat-resistant materials, mainly used to reduce the screw threads in the high-temperature state of the bonding effect.
5. Tin-plated, tin-plated steel wire threads inserts have the biggest advantage of better corrosion resistance, for corrosion resistance has high requirements, you can consider tin-plated coating of steel wire threads.
6. Dry film lubrication for mild corrosion or high temperature environment.
