EZ33A
UNS M12330
Description
Magnesium alloy EZ33A is a magnesium-rare earth element-zinc-zirconium alloy with the characteristics of good castability and damping capacity, pressure tight, creep resistant to 245 ℃. It is typically used in commercial and military pressure-tight sand and permanent-mold castings relatively free from microporosity.
