The copper content of 3% makes the alloy heat resistant. Adding a zinc content of 2% enables the alloy to be hardened in eight days at room temperature. As a result, T5 heat treatment is not necessary, but can be performed if desired. The manganese content of 0.8% prevents sticking to the die and provides temperature stability at the same time. By adding strontium to trimal®-41, the eutectic silicon is refined, thus improving ductility. In addition, strontium creates a slight spheroidizing of the intermetallic phases. The copper content limits the corrosion resistance. Chemical composition The following table shows a reference analysis for the described material in weight percent.

It is used mainly in applications such as engines or motor parts, casings or end plates that require great stability at, for example, elevated temperatures. The alloy can be used to cast complicated designs and very thin walls. trimal®-41 is well machinable. It can be hard anodized to improve the tribologic properties. trimal®-41 product information sheet Download the product information sheet for our trimal®-41 die casting alloy here.
