what would be the correct order if Zn,Fe,Al and Cu are arrange in increasing order of reactivity
Answers
Cu,Fe,Zn,Al
hope it helps u ^-^
Cu < Fe < Zn < Al.
Mostly, commercially used, alloys of aluminum-casting depend on an aluminum-silicon framework because of its superb casting, and great mechanical, properties.
Sadly, these Al-Si based compounds are inalienably poor conductors of energy; in comparison with unadulterated aluminum, considering their high silicon part.
This implies they are not reasonable for applications requesting high electrical or thermal conductivity.
In this manner, endeavors are as of now being made to grow new, very conductive aluminum-casting composites containing no silicon.
In this finding, various properties; including the potential for castability, were examined for various Al-Fe-Zn-Cu composites with shifting Cu content.
As the copper content was expanded, the elasticity of Al-Fe-Zn-Cu composite would in general increment step by step, while the electrical conductivity was somewhat decreased.
Ease was observed to bring down in high-Cu amalgams, and defenselessness to hot-breaking was commonly high in all the composites researched.
