Material sections
5052 aluminium head riveted to a copper-plated, galvanized or stainless steel wire.
Bimetallic Pins
Combine two specified metals in one insulation pin for the required welding surface and fastening environment.
Bimetallic pins use two joined metal sections within one component. Confirm the material at the welding end, the material along the pin body, the connection geometry and the intended substrate before selecting the dimensions and welding setup.
- Diameter
- 3 mm
- Length
- 30–300 mm
Quotation is based on the confirmed material combination, dimensions, joint construction, substrate, welding requirements and quantity.
Materials & dimensions
Bimetallic pin
specifications.
Confirm the material used at each end of the pin together with the diameter, total length, section lengths and joint position. Share the substrate and service environment so the complete construction can be reviewed before quotation.

Product details
Two metal sections
in one pin.
The product construction should be described by the material and grade of each section, the position and geometry of the joint, and the method used to join the metals. These details affect welding, installation and service performance.
Weld point detail
Welded with the same approach as CD weld pins; confirm the weld point for your substrate.
The aluminium head is press-riveted to the wire. Confirm the material combination for your substrate and service environment.
Compatibility
Choosing the metal
for each section.
The welding-end material should be selected for the intended substrate and welding process. The remaining pin section should be selected for the insulation system, retaining component and service environment. The complete metal combination must then be reviewed for joint integrity and environmental compatibility.
