Welding of Aluminum Alloys

Aluminum and its alloys can be joined by more methods than any other metal, but aluminum has several chemical and physical properties that need to be understood when using the various joining processes. The specific properties that affect welding are its oxide characteristics, its thermal, electrical, and nonmagnetic characteristics, lack of color change when heated, […]

Practical Aspects of Modern Inert Gas Welding Of Aluminum

The specific demands made on welded constructions require the application of the most suitable alloy. Pure aluminum and the Al-Mn alloy are still in use for the construction of containers and chemical appliances owing to their favorable prices and good corrosion resistance, wherever the demands made on the mechanical resistance are not excessive. Typical alloys for the manufacture of vessels and containers, and indeed as welding materials, are the non-heat-treatable alloys Al-Mg or Al-Mg-Mn, which still have a medium resistance in the soft state.

Aluminum Extrusion Industry

Extruded Aluminium Sections Aluminum extrusions are linear aluminum products highly valued in a wide spectrum of structural applications due to aluminum’s high strength-to-weight ratio and the cost effectiveness of the metal extrusion process. Like other types of metal extrusions, extruded aluminum is either hot extruded or cold extruded through a die, shaping aluminum stock into

Thermomechanical Treatments of Aluminum Alloys

Thermomechanical processes are defined in the broadest sense to include any combination of thermal or deformation processes that give rise to interactive microstructural features. The varieties of mechanisms involving the creation, rearrangement and elimination of dislocations and grain boundaries are reviewed to show the range of possibilities in microstructure and property production. The interactions of
