The mechanical properties of YL113 can be systematically enhanced to meet a wider range of applications through the following combination of strategies:<\/p>\n\n\n\n
- \n
- Microalloying and composition optimization<\/strong>The following are examples: strict control of iron content (\u22640.7%) and addition of trace titanium (Ti: 0.1-0.15%) for grain refinement; and control of copper content at the upper end of the range (~2.5%), which significantly improves the room and high temperature strengths.<\/li>\n\n\n\n
- Advanced Die Casting Process<\/strong>: Adoptionvacuum die casting<\/strong>(Vacuum degree \u2264 50mbar) can reduce the porosity to below 1%, fatigue strength enhancement 20-30%; on the thick and large parts using thelocalized extrusion<\/strong>The technology effectively eliminates shrinkage holes and improves density and strength uniformity.<\/li>\n\n\n\n
- heat treatment strengthening<\/strong>: The most cost-effective way to reinforce YL113 is toT5 manual aging<\/strong>(Holding at 150-180\u00b0C for 4-8 hours). After T5 treatment, its tensile strength can be increased to270-310 MPa<\/strong>Yield strength up to180-220 MPa<\/strong>It is suitable for die castings that require high strength but cannot be subjected to drastic solution treatment, while maintaining good dimensional stability.<\/li>\n<\/ol>\n\n\n\n
