Description
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.
