Custom Heavy Aluminum Die Casting Services Metal Fabrication Specialist

As a specialized metal fabrication expert, we provide custom heavy aluminum die casting services for large-scale, high-integrity components. Our manufacturing capabilities are specifically engineered to handle substantial aluminum castings, combining advanced die casting technology with comprehensive metalworking expertise to deliver robust solutions for demanding industrial applications.

Material Selection and Performance Characteristics

We specialize in high-strength aluminum alloys optimized for heavy-section die casting:

A360 Aluminum Alloy
This premium alloy offers exceptional pressure tightness and corrosion resistance, with tensile strength of 324 MPa and yield strength of 165 MPa. Its superior fluidity enables production of complex heavy components with minimal porosity.

A380 Aluminum Alloy
As the industry standard for heavy die casting, A380 provides an optimal balance of strength, corrosion resistance, and castability. The alloy maintains dimensional stability in large configurations with tensile strength reaching 330 MPa.

*Modified 356-T6*
For applications requiring enhanced mechanical properties, we offer heat-treatable 356 alloy achieving tensile strength of 262 MPa after T6 treatment, ideal for structural components subject to high stress loads.
