Aluminum Mig Wire for Marine Shipbuilding
As one of the marine aluminum suppliers, Haomei Aluminum also provides aluminum welding wire for shipbuilding. Aluminum welding wire is mainly divided into two categories: pure aluminum welding wire and aluminum alloy welding wire. Pure aluminum welding wire refers to pure aluminum welding wire with more than 99.7%, which is usually used for welding pure aluminum materials.
Its main characteristics are excellent oxidation resistance and good electrical conductivity, which is suitable for high-quality welding of pure aluminum materials, such as aircraft and satellite devices in the aerospace field.
Aluminum alloy welding wire mainly refers to aluminum welding wire that has been alloyed, which is usually used for welding aluminum alloy materials. Aluminum alloy welding wire can be divided into many types according to the different alloy components. The common ones are as follows: 4000 series aluminum alloy welding wire. It contains silicon, with excellent fluidity and crack resistance, which is suitable for welding cast aluminum alloys, aluminum silicon alloys, etc.
5000 series aluminum alloy welding wire is a magnesium-containing aluminum alloy welding wire with good corrosion resistance and strength, suitable for welding magnesium-aluminum alloy. 6000 series aluminum alloy welding wire is an aluminum alloy welding wire containing silicon and magnesium. It has good tear resistance and plasticity and is suitable for welding aluminum-magnesium-silicon alloy. 7000 series aluminum alloy welding wire is an aluminum alloy welding wire containing zinc. It has good strength and heat resistance and is suitable for welding high-strength aluminum alloy.
What are the differences between aluminum silicon and aluminum magnesium wire? How to choose the right welding wire?
Magnesium is the main alloying element of various rust-proof aluminums except 3A21 (LF21) alloy. The magnesium content of deformed magnesium alloys is <5.5%, and the magnesium content of cast Al-Mg alloys is 4% to 10%. Adding manganese can make the magnesium-containing phase evenly distributed, improve strength, corrosion resistance and weldability.
Due to its good corrosion resistance, it is used in automotive parts processing, chemical storage containers and cryogenic pressure vessels, as well as building structures, rail transit carriages, cars, dump trucks and bridges.
As an aluminum welding wire, 5356 Aluminium mig wire is the most common, and other aluminum-magnesium welding wire models include 5183, 5087, 5556, 5A06, 5B06, 5554, etc.
