Analysis of Different Porosity in Aluminum Die Casting

Different kinds of porosity for die casting die casting porosity Porosity caused by poor refine of material.Weiheng Die Casting is professional to control porosity. The temperature of melted aluminum alloy normally is 610-660℃ in die casting.At this temperature,there is lots of gas(mainly hydrogen) in melted alloy.At 660℃,hydrogen is 0.69cm3/100g in melted aluminum alloy,while it is 0.036m3/100g in solid aluminum alloy.Therefore,there is lots of hydrogen bubble contained inside aluminum die castings. The refine of melted aluminum alloy is to reduce gas in melted aluminum [...]
