Spot Welding Electrode Tip

Introduction

This product is made of a nanocomposite consists of copper alloy reinforced with aluminum oxide nanoparticles with the average size of 10 nm, which are uniformly distributed in the copper matrix. Aluminum oxide is produced through a process in which oxygen reacts with aluminum in the copper lattice in the solid state. This method, in comparison with other techniques, has the best particle size and distribution. Aluminum oxide is very hard, thermally stable and insoluble in copper. These particles not only increase the copper alloy strength but also have no significant effect on reducing the thermal and electrical conductivity of copper. The electrode tips are produced in different male or female types by cold forming process or in some cases by the machining process. 

Application

• Assembly of the car body (robotic and manual)
• Home appliances
• Aerospace industries (welding)

Advantage of Using Nanotechnology

Addition of aluminum oxide nanoparticles increases the hardness and tensile properties of the copper alloy. These features are created through the pinning of dislocations by aluminum oxide nanoparticles, which consequently postpone the crystallization process.
