Stick Electrodes MTC MT-AlSi 5 for Aluminum

Stick electrode with special coating for welding aluminum-silicon alloys. Weld metal made of aluminum-silicon alloy.

Important applications for MTC MT-AlSi 5 stick electrodes:

Aluminum-silicon alloys, as well as dissimilar aluminum alloys among themselves. Conditionally for hardenable alloys such as AlCuMg 1 (3.1325), AlMgSi 1 (3.2315), AlZn 4.5 Mg 1 (3.4335)

Mechanical properties of the weld metal (typical values)

Base material Material thickness Heat treatment Test temperature [mm] [°C] AlMgSi 1 6 untreated +20°C 0.2% yield strength Rp0.2 MPa 90 Tensile strength Rm MPa 160 Elongation at break A5 [%] 15

Special notes:

Guide the stick electrode with a short arc perpendicular to the base material. For larger workpieces and wall thicknesses over 15.00 mm, preheat the weld joint area to +150°C - +200°C. Since the pure weld metal is not hardenable, when welding hardenable aluminum alloys, the weld seams should not be placed in mechanically highly stressed areas.
