Electrical Tungsten Contact Rivets

Electrical Tungsten Contact Rivets

Xiamen Apollo is now recognized as a leading manufacturer and supplier of Tungsten Electrical Contacts in China. These are primarily used in Automotive Electric Horns, Distributor Contact Breaker Assembly, and Relays etc. Our entire assortment of Tungsten Discs and Tungsten Contact Rivets are manufactured in our factory. 


Tungsten Powder Sintering Disks: 

1-Tungsten content: ≥99.95%

2-Density: 18.2g/cm3 

3- Hardness: HV1≥325 

4- Grain size: 11500 ps/mm2 

5- Process: Tungsten powder pressing and sintering


Flat Tungsten Contact Points for Motorcycle Horn are formed by brazing (welding/soldering) tungsten disc with Copper Rivet or Mild Steel Rivet. The Flat Head Rivets are made according to customer specifications and requirements. The Tungsten Copper Electrical Contact are plated by pure nickel to make it corrosion resistant. Tungsten Contact for Motorcycle Horn are widely used in high frequency make and break applications such as automobile horns, relays and distributor point.

1. Tungsten Contact Rivets Processing Requirements

With the continuous development of the automobile manufacturing industry, the requirements for tungsten contact materials are rapidly increasing. The user's requirements for tungsten contact materials are: 

(1)Rod without cracks, scratches, smooth surface; 

(2)Fine and uniform cross-section grains, short fibers; 

(3)Good straightness, concentricity and roundness; 

(4)High hardness, good impact toughness; 

(5)Vapor pressure Low evaporation rate, small thermal expansion coefficient; 

(6)Good and stable arc resistance. 


Physical and mechanical properties of Motorcycle Horn Tungsten Rivet materials In order to meet user requirements, technicians have done a lot of work. For the splitting, brittle fracture, and uneven grain size of the cross-section during the production process of the Solid Tungsten Contact Rivets material, the rod diameter is the same. The reasons why the O degree and flatness can’t meet the requirements are comprehensively analyzed, and a series of measures are taken pertinently.

2. Electrical Tungsten Contact Rivets Material Characteristics

Tungsten is used as electrical contact or contact material, which is resistant to arc ablation; good fusion resistance; metal surface evaporation caused by electrothermal action, less transfer and consumption; strong current interrupting ability; and good wear resistance, dynamic hit performance. Compared with other metal or alloy materials, the price is low, so tungsten contacts and tungsten wafers are widely used in various fields of industry, agriculture, technology and defense.

Solid Tungsten Contact Rivets is characterized by its advantageous properties of high melting and boiling points, sufficient electrical and thermal conductivity and high hardness and density .Industrial Tungsten Brazed Contacts Rivets are mainly used in the form of brazed contact tips for switching duties that require a rapid switching sequence such as Car Horn Tungsten Contact Rivets for cars and trucks.
