ASTM standard 4343 aluminum alloy sheet

4343 aluminum plate

 4343/3003/ASTM standard 4343  clad ingots had been ready by liquid-solid casting. The microstructure, elements distribution and interface bonding strength of your clad ingots were investigated. The interface bonding mechanism on the clad ingots was analyzed. The outcomes indicate that when the pouring temperature of 4343 aluminum alloy is 725-750℃, the metallurgical bonding of clad ingots is good, and along with clear and flat interface.

The metallurgical bonding interface of clad ingots consists of ASTM standard 4343  Al-Si solid option layer and diffusion layer of Si and Mn. The thickness of Al-Si strong answer layer is uniform. The diffusion distances of Mn and Si are 10μm and 32μm, respectively.The bonding strength of clad ingots is larger than the ultimate tensile strength of 3003 aluminum alloy.

The interface bonding mechanism of liquid-solid 4343/ASTM standard 4343  clad ingot is as follows:firstly, the 4343 aluminum alloy melt is rapidly solidified around the the top of 3003 aluminum alloy ingot to form the Al-Si strong option layer, then the Si inside the Al-Si solid solution layer and the Mn within the 3003 aluminum alloy interdiffused to kind the clad ingot with excellent metallurgical bonding interface.
