Sifmig 5183 Aluminium MIG Wire – 1.2 mm x 6.5 Kg

Special aluminium alloy containing:

  • 5% Magnesium
  • 0.75% Manganese
  • For improved weld strength.

Can be used to weld forged and cast aluminium-manganese and aluminium-manganese alloys in applications where high tensile strengths and/or high resistance to sea water is required.

Typical applications include ship building, pressure vessel fabrications and general construction.

Pre-heating up to 1200C may be necessary, subject to material size and thickness. Wire brushing between passes is recommended to ensure removal of surface oxide build up.
