TIG Aluminium alloys

Below are the most common alloys for aluminium welding. We also have more unusual alloys in our product line ex. AlMg3Mn(5554), AlMg4,5MnZr(5087), Al99,5Ti(1450), Al99,7(1070) m.m.

aluminium tig

Meltolit Al99,5 (1050)

For welding of unalloyed aluminium in chemistry, electronics, construction and food industries.

Meltolit Al99,7 (1070)

For welding of mostly pure aluminium in chemistry, electronics, construction and food industries.

Meltolit Al99,5Ti (1450)

For welding of mostly pure aluminium in chemistry, electronics, construction and food industries. Titanium addition is giving a higher corrosion resistance.

aluminium tig

Meltolit AlSi5 (4043)

Aluminium tig wire for welding aluminium alloys containing up to 7% Si. Excellent flowability and penetration characteristics. Applications in construction sector and automotive industry.

aluminium tig

Meltolit AlSi12 (4047)

Aluminium tig wire for welding and brazing. Good mechanical characteristics and its generally used for brazing aluminium sheets, for extrusions and castings.

Meltolit 4145

Aluminium tig wire for welding and brazing. Low melting temperature and high fluidity. Gives a very high resistance to weld cracking when used with 2-series aluminium, aluminium-copper, or aluminium-copper-silicon castings.

aluminium tig

Meltolit AlMg3 (5754)

For welding aluminium base alloys with maximum 3% Mg. For construction and general industry. Corrosion resistant.

Meltolit AlMg3Mn (5554)

Alloy 5554 was originally developed as a filler alloy for use with alloy 5454 as this combination of alloys does not become sensitive to stress corrosion cracking at elevated temperatures.

aluminium tig

Meltolit AlMg4,5Mn (5183)

For welding aluminium base alloys that require high mechanical properties. Construction, offshore and automotive industry. Very good saltwater resistance.

Meltolit AlMg4,5MnZr (5087)

For welding aluminium base alloys that require high mechanical properties. Construction, offshore and automotive industry. Very good saltwater resistance. Zr improves bending and corrosion resistance.

aluminium tig

Meltolit AlMg5 (5356)

For welding aluminium base alloys with max 5% magnesium. Construction, ships, tanks and automotive industry. High corrosion resistance. 

Meltolit AlMg5Mn (5556A)

For welding aluminium base alloys with max 5% magnesium where high tensile strenght is required. Addition of Ti increases corrosion resistance and decreases heat cracks. General construction, military industry.
