Weldability refers to the joinability of the material. The differences in the melting point, surface condition of the material, electrical resistance, thermal expansion, reactivity, are just a few factors that affect welding. Weld integrity is very important when it comes to material selection for aircrafts. The microstructures of the alloys have a great role to play in determining the weldability of the resultant metal. Alloy selection is done after due weldability evaluation mainly with respect to mechanical properties and susceptibility for hydrogen cracks. 

High Strength to Weight Ratio
The 2024 aluminum plate is an alloy of aluminium and copper. It has a high strength to weight ratio. It is widely used in the aircraft wheels and in some truck suspension parts. The weldability for 2024 aluminum plate is minimal. However, when it comes to alloy and material selection whether the material will meet the purpose of the construction in which it will be used for is taken in to consideration.

A Need for Cost Reduction
Most of the aircraft manufacturers are in need of aluminium suppliers who can cater to their demands like 321 stainless steel tubing supply and several other needs. There is forever a need for cost reduction without compromising on the quality parameters in every industry and the aircraft building industry is no exception. When it comes to using cost effectively designed aluminum components it becomes necessary to reduce the usage o
f thick plates; however, at the same time increasing the usage of extrusions and forgings. With continual research new manufacturing techniques in terms of improved quality in aluminium castings, integrally extruded wing fuselage panels, and better welded structures are becoming a norm. Component structures and their relative success is frequently studied, compared and authenticated.

Improve On the Structural Efficiencies
In order to improve the structural efficiencies of wings over conventionally riveted structures, welding techniques are greatly improved. This is evidence in cases of friction stir welding technology and laser beam welding technology. The light weight and anti-corrosive properties of aluminium has provided the alloy with great success with respect to the lightweight, energy saving, recycling, and energy saving properties of the metal.

Suppliers with Improved Quality
Suppliers who can provide aircraft quality materials are forever in demand in the aerospace manufacturing sector. Scrap providers are not able to supply for the growing demands in aircraft production technology. Therefore, aluminium suppliers with improved quality are forever in demand. The need for aluminium alloys in primary structures like in fuselage skin, wing skin, stringers, and primary forging alloys and in several other secondary structural applications are here to stay. When it comes to commercial aircraft manufacturing, schematic research is happening to identify different alloys of metal. Research is never going to end, and with new innovations happening around, suppliers will have to improve their capability to provide the required alloys.
