TIG rod copper (ERCuSi-A). Neutral

Per page:

The solid copper rod for TIG welding is used as a filler material for joining and repairing copper alloys. As it is applied manually, it allows the amount of material deposited to be controlled and enables precise work on pipes, parts and industrial components.

This category includes the copper-silicon rod S Cu 6560 (CuSi3Mn1), classified in accordance with the UNE-EN ISO 24373 standard. It is primarily intended for use with copper-silicon alloys and bronzes of a compatible composition. Its composition promotes the fluidity of the weld pool and helps to produce uniform weld beads when used on compatible materials.

It is available in various diameters to adapt the amount of material deposited to the thickness of the workpieces and the characteristics of each joint.

Applications of copper TIG rods

These rods are used in the manufacture and repair of pipework, industrial parts and components made from silicon bronze or similar alloys.

They are also suitable for work where resistance to corrosion and good performance under mechanical stress are required. Before selecting a rod, it is important to check the composition of the base metal, as a copper-silicon grade is not suitable for all copper alloys.

How to choose a copper rod for TIG welding

The selection must take into account the composition of the parts, their thickness and the operating conditions of the joint.

The S Cu 6560 grade is designed for copper-silicon alloys and compatible bronzes. Choosing the correct diameter allows for better control of the amount of filler material and enables the process to be adapted to each application.
