Aluminum casting is generally divided into aluminum alloy casting and high pressure casting, people often say that die casting refers to high pressure die casting, is the use of die casting machine will melt aluminum alloy profile high-speed compression mold, and under high pressure rapid cooling molding. Usually casting is divided into sand casting, gravity casting, low pressure casting, dewaxing casting, differential pressure casting, ceramic casting, gypsum casting and so on.

Therefore, aluminum alloy casting means the aluminum alloy obtained by the usual casting method, and die casting aluminum alloy means the aluminum alloy obtained by the high pressure die casting process.

Countries around the world for casting aluminum alloy and die casting aluminum alloy naming way is not the same, China's GB specification will cast aluminum alloy with ZL+3 digit expression, such as ZL101 that cast aluminum alloy, die casting aluminum alloy with YL+3 digit expression, such as YL102; The Japanese JIS standard will cast aluminum alloy with 4 words to describe, such as AC4C, A means aluminum, C represents a series, 4C means classification; Die-cast aluminum alloy is expressed with ADC+2 digits, such as the most common ADC10, ADC12; In the American ASTM standard, cast aluminum alloy is expressed with A+3 digits. When the value of at least 3 digits exceeds 359, it is die-cast aluminum alloy, and when it is less than equal 359, it is cast aluminum alloy. The most commonly used A380 is a die-cast aluminum alloy, and the A356 is a cast aluminum alloy, which is mainly used for gravity casting.

Casting aluminum alloy is very easy to make an anode, and die-cast aluminum alloy is very difficult to make. But die casting aluminum alloy for electroplating relative better.
