bimetallic or trimetallic rivet; Which order structure is more suitable?

Choosing between bi-metal and tri-metal should start from the need of the switching surface, assembly method, geometry and control of alloy consumption; Not just from the name of the structure.

Choice of bimetallic or trimetallic structureTechnical analysis of SGEI

What is controlled in the bimetallic structure?

The working layer is placed on the switching surface and completes the body, the shape of the head and shank. Layer thickness, junction location and formability should be seen in the drawing and sample.

When is the trimetallic structure checked?

Three regions are defined for the work surface, the body, and the end or junction region. This structure makes sense when each area has a clear and controllable role.

The presence of an additional interface means more need to control the section, continuity and repeatability of the process.

Close the decision with an example

Cost comparison is valid only after equalizing dimensions, thicknesses, alloys and production quantity. The sample should be riveted to the actual carrier and evaluated under the conditions of the switching agent.

The next step

To convert these principles into orderable specifications, provide part drawing, switching conditions, assembly method and production quantity together.
