Aluminum alloy die casting VS Zinc alloy die casting
zinc vs aluminum weight: zinc win
zinc vs aluminum cost :It’s depand on the die casting product struture. In general .small part (zinc die casting win),large die casting parts (aluminium die casting win)
zinc vs aluminium surface treament: aluminium win process: anodize,heat treatment,polish,sand blasting
zinc die casting process: plating,
other die casting surface treament similiar
The main alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements such as nickel, iron, titanium, chromium, lithium and so on.
The density of aluminium metal is 2.75 g/cm3.
Classification of aluminium alloys: Aluminum alloy is divided into two categories: casting aluminum alloy, in the casting state of the use; deformation of aluminum alloy, can withstand pressure processing, mechanical properties than cast state. Aluminum alloy materials can be processed into various shapes and specifications. Mainly used in the manufacture of aviation equipment, daily necessities, building doors and windows, etc..
Aluminum alloy processing method:Aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy. cast aluminum alloy can be divided into non heat treated aluminum alloy and heat treated aluminum alloy. The non heat treatment enhanced mechanical properties can not be improved by heat treatment, only through the cold processing deformation to achieve strengthening, it mainly includes high pure aluminum, industrial high purity aluminum, industrial pure aluminum and rust proof aluminum, etc.. Heat strengthened Aluminum Alloy can improve mechanical properties by quenching and aging heat treatment, it can be divided into hard aluminum, aluminum forging, aluminum and special Aluminum Alloy etc..
zinc die casting
Commonly used for electroplating zinc base alloy material of the brand is 4-1 ZnAl, composition (%): Al 3.5 ~ 4.9, Cu 0.75 ~ 1.25, Mg 0.03 ~ 0.08, the margin is Zn. The density of zinc metal is 6.75g/cm3 ,
Zinc die Casting performance is good, can cast complex, thin wall precision,surface smooth shape and parts.zinc is heaviest materail ,so suggest to cast small part .
Zinc has good Surface treatment , It has smooth surface by electroplating, spraying, painting
It has good mechanical properties and wear resistance
The low melting point at 385 DEG C melting, easy casting
