The effect of the surface condition of aluminium ingot (AA 3003) during roll bonding with the clad aluminium alloy AA4343 to form an aluminium brazing material
The thesis focuses on the brazing material that is made at Hulamin in Pietermaritzburg. The brazing material is made by hot rolling two Aluminium alloys together that is AA3003 and AA4343 in forming a metallurgical bond. The strength of this metallurgical bond is determined by the surface condition of the core AA3003 and the clad AA4343 prior to rolling. In a way to optimize this hot rolling process the thesis has to alter the surface roughness of the core and the clad and perform a simulation of hot rolling and determine which one has a good bond quality and then recommend to Hulamin.
