Abstract
Methods and systems for high pressure die casting with metal alloys of low silicon content are described. Metal alloys can be modified with nanoparticles to achieve high fluidity and hot cracking resistance to be compatible with high pressure die casting. The die cast metal parts have high strength, high ductility, and high thermal and electrical conductivity. The die cast metal parts can be anodized with different colors.
Claims12
A method for die casting comprising:
- melting a metal alloy, wherein the metal alloy is modified with at least one type of nanoparticle, wherein the metal alloy comprises a silicon weight concentration of less than 4.0%;
- filling a die with the molten metal alloy under a pressure greater than 100 MPa;
- and
- cooling the die to solidify the molten metal alloy with a cooling rate between 100° C./s and 300° C./s.
