Introduction
Aluminium / aluminum is a lightweight silverish white metal, which when combined with one of these elements -manganese, copper, silicon, magnesium, and zinc, forms aluminium / aluminum alloys. Initially, aluminium / aluminum alloys were widely used in aerospace manufacturing; however today it is used in hundreds of components in myriad fields.
Aluminium / aluminum 4145 alloy is a heat treatable wrought alloy type with good corrosion resistance. It is a filler metal, and provides very low susceptibility to weld cracking when used with 2xxx series alloys and with aluminium / aluminum-copper or aluminium/aluminum -copper-silicon castings.
The following datasheet will provide more details about aluminium / aluminum 4145 alloy.
