Beyond Standard Grades: The Vastmaterial Difference
We move beyond the limitations of commodity materials like ADC12 и A356. While standard castable aluminum alloy grades often force manufacturers to choose between mold filling capability and mechanical integrity, our proprietary HY Series eliminates this trade-off. We engineer materials that deliver the fluidity required for complex Al-Si casting series geometries while achieving the mechanical performance traditionally reserved for forged components.
Solving the Castability vs. Strength Dilemma
Our development focus is on “casting instead of forging” and “casting instead of steel.” By refining grain structures and controlling impurity levels, we provide structural die casting materials that allow for significant lightweighting without compromising safety.
- High-Strength & Toughness (HY-1 Series): Engineered for safety-critical parts in automotive and aerospace. These alloys achieve Tensile Strength ≥ 480-520 MPa, Yield Strength ≥ 380-420 MPa, и Elongation ≥ 5-10%, outperforming standard A356 варианты.
- Heat Resistant Performance (HY-5 Series): Designed for high-temperature environments. Unlike standard alloys that lose strength rapidly, HY-5 maintains integrity at operating temperatures up to 300°C – 350°C.
- Process Versatility: Our alloys are optimized for various methods, including Горячее прессование под высоким давлением (HPDC), low-pressure, and gravity casting, ensuring near-net-shape precision.

Microstructure and Grain Refinement
The superior mechanical properties of our castable aluminum alloy stem from advanced grain refinement technologies. Unlike the coarse grain structures found in generic ingots, our process achieves a highly refined, uniform microstructure.

- Fatigue Resistance: The refined grain structure provides exceptional fatigue strength, making these alloys suitable for dynamic automotive and aerospace loads.
Обрабатываемость и качество поверхности
Post-casting operations are often where costs spiral. Our alloys are designed to be chip-friendly, reducing tool wear rates compared to high-silicon abrasive alloys. The consistent density ensures a mirror-like surface finish after polishing or coating. For projects requiring tight tolerances, our material stability supports high-precision услуги ЧПУ обработки without the risk of stress-induced warping common in lower-grade metals.
Spotlight Technology: Heat-Treat-Free (HTF) Alloys
Standard T6 heat treatment is often a production bottleneck, introducing risks like dimensional distortion, surface blistering, and significant energy consumption. We developed our Heat-Treat-Free (HTF) castable aluminum alloy series to eliminate these issues entirely while maintaining structural integrity. By achieving high mechanical properties in the “As-Cast” state, we help foundries bypass the quenching process that typically warps large components.
Switching to HTF alloys offers immediate advantages for high-volume manufacturing:
- T6-Level Strength: Our alloys deliver yield strength and elongation comparable to heat-treated A356 without the extra processing steps.
- Cost Reduction: Eliminating heat treatment cycles and post-process straightening lowers total manufacturing costs by 20-30%.
- Zero Thermal Deformation: Идеально для Gigacasting and large automotive structural parts (like shock towers and subframes), ensuring the casting retains its precise shape from the mold to assembly.
For engineers evaluating specific material properties, our Alloy Guide for High Performance Alloys and Precision Casting provides detailed comparisons of these structural die casting materials against traditional grades.

Our alloys are optimized for exceptional fluidity, which is critical for filling complex molds in high-pressure die casting (HPDC). This high fluidity allows for the production of thin-walled, near-net-shape components that standard commodity ingots often struggle to fill. This capability enables significant weight reduction in structural parts without compromising integrity.
Do you provide material certificates (mill test reports) with every shipment?
Yes, full traceability is standard procedure. Every batch of castable aluminum alloy ingots ships with a comprehensive Mill Test Report (MTR). This documentation verifies the chemical composition and mechanical properties—including yield strength, tensile strength, and elongation—confirming that the material meets your specific engineering requirements before it hits your production floor.
Can you customize the silicon content for specific machining requirements?
We don’t just sell standard ingots; we provide engineered material solutions. Our R&D team can adjust micro-alloying elements, such as Silicon (Si) and Magnesium (Mg), to balance mechanical toughness with machinability. Whether you need to optimize for tool life or specific surface finish quality, we can tailor the alloy composition to align with your manufacturing process.
