I don't know. Did you read it when you answered the question? What is the best casting temperature for aluminum castings? Aluminum alloy is not iron, but copper alloy. Generally, aluminum alloy is at 700-740℃. If the temperature is too high, it is easy to burn off the magnesium component in the total amount. Excessive temperature will also increase the total air intake, and the product is prone to pinholes and blowholes.
