Frequently Asked Questions (FAQ)

What are the five grades of aluminum welding consumables?

ER1100 is industrial pure aluminum welding wire (refer to Russian standard Св-А5); ER4043/AlSi5 aluminum-silicon alloy welding wire (Св-АК5); ER5356/AlMg5 aluminum-magnesium alloy welding wire (Св-АМг5); ER5183/AlMg4.5Mn High-strength aluminum-magnesium welding wire (Св-АМг6); ER4047/AlSi12 high-silicon brazing wire, covering pure aluminum to aluminum-silicon, aluminum-magnesium series.

What are the uses and characteristics of ER4047/AlSi12 high silicon welding wire?

What are the characteristics of the physical and mechanical properties of aluminum alloy welding materials?

In what industries are aluminum and aluminum alloy welding materials used?

It is widely used in automobile manufacturing, aerospace, shipbuilding industry, pressure vessels and other fields. Aluminum welding materials have excellent electrical conductivity, thermal conductivity and excellent corrosion resistance, which can ensure the welding strength and quality of lightweight structures. They are key filling materials for lightweight equipment manufacturing.

What are the differences between the packaging specifications of aluminum welding wire and steel and nickel welding wire?

Aluminum welding wires are mainly coiled wires, usually 0.5kg, 2kg, or 7kg/roll (depending on the diameter), which are significantly smaller than the 5-25kg common coils of carbon steel and nickel-based welding wires; there are also precision diameters of 0.2-0.8mm for thin plate welding, and welding rods with diameters of 2.0-5.0mm and lengths of 300/350/400mm.
