Introduction
ZE41 is a magnesium casting alloy containing zirconium, rare earths and zinc. This alloy is well-suited for high integrity castings that are operated at ambient temperatures or up to 149°C (300°F). It is easily weldable and pressure-tight.
The following datasheet will provide more details about ZE41 alloy.

Manufacturing Process
ZE41 alloy is machined like any other magnesium casting alloys, using conventional techniques. It is heat-treated at optimum temperatures ranging from 177-343°C (350-650°F) for 10 to 16 hours. This process is followed by water quenching. The alloy is welded by TIG process using filler rod of a similar composition.
