Description

SIFMIG 4043 – Aluminium MIG Wire – 1.2 mm x 6.5 Kg

SIFMIG 4043 Aluminium MIG Welding Wire, with a diameter of 1.2mm, is an aluminium alloy infused with 5% silicon. This composition ensures excellent flow characteristics and penetration. It’s designed for gas-shielded MIG welding and is compatible with both semi-automated and fully-automated systems. This wire is particularly suitable for welding duralumin, cast and wrought alloys like 6063 (H9), 6061 (H20), and 6082 (H30). However, it’s essential to note that the weld will discolour if anodised.

Key Features:

• Contains 5% Silicon, ensuring excellent flow and penetration.
• Precision layer-wound for consistent and uninterrupted feeding.
• Suitable for welding specific aluminium alloys, including duralumin, 6063 (H9), 6061 (H20), and 6082 (H30).
• Welds may discolour upon anodising.

Common Applications:

SIFMIG 4043 Aluminium MIG Welding Wire is ideal for:

• Welding duralumin.
• Welding cast and wrought alloys like 6063 (H9), 6061 (H20), and 6082 (H30).
• Other 4 series aluminium applications.

Material To Be Welded

Suitable for welding duralumin, cast and wrought alloys 6063 (H9), 6061 (H20) and 6082(H30), as well as other 4 series aluminium. The resulting weld will discolour if anodised.

Pre-heating up to 120 degC may be necessary, subject to material size and thickness. Wire brushing between passes is recommended, to remove build up of surface oxides.

Ensure that the parent metal surface is cleaned and fully degreased prior to welding. Clean joints with a stainless steel brush.
