Performance Enhancement Pathways and Technical Characteristics
The ADC10Z is designed with the concept of “Maintain strength advantage, optimize cost and manufacturability”：
- Optimized adjustment of zinc content: Relaxation of the upper limit of zinc content from ≤1.0% in ADC10 to ≤1.5%, which is the core feature that distinguishes ADC10Z from ADC10. Appropriate relaxation of zinc contentHelps improve casting fluidity and reduce material costsIt also does not significantly affect the mechanical properties and corrosion resistance.
- Solid Solution Strengthening of Copper: A copper content of 2.0-4.01 TP3T is at the heart of the high strength gained by ADC10Z. Copper forms the Al₂Cu phase in aluminum, which significantly increases cast strength and hardness through solid solution strengthening. The higher the copper content, the higher the strength, but with a corresponding decrease in elongation and corrosion resistance.
- Processability of Silicon Guaranteed: Silicon content of 7.5-9.5% makes its fluidity among the best in die-casting aluminum alloys, low shrinkage, low tendency to thermal cracking, suitable for molding complex thin-walled structures. The presence of silicon also partially improves wear resistance.
- Not heat treatable: As with ADC10, ADC10Z does not contain sufficient age strengthening elements such as magnesium.Unable to improve strength by T5/T6 heat treatment. This makes it a simplified production process, cost-controlled and suitable for mass production.
- Cost Advantage: By optimizing the zinc content, ADC10Z maintains the high performance of ADC10 whileSlightly lower raw material costsIt is one of the most cost-effective materials for the die casting industry.

- In practice, the ADC10Z and ADC10 are often considered interchangeable. When selecting the model, if there are higher requirements for casting fluidity or the pursuit of cost-effective, you can choose ADC10Z; if there are strict standards for composition control, you can choose ADC10.
Q2: What is the difference between ADC10Z and ADC12? How to select the model?
- comparative analysis:
- ADC10Z: Silicon 7.5-9.5%, Copper 2.0-4.0%, Zinc ≤1.5%.High strength and good castability, is the universal option.
- ADC12: Silicon 9.6-12.0%, Copper 1.5-3.5%, Zinc ≤1.0%.Higher silicon content for better castabilityIt is the mainstream common grade in the current JIS standard.
- selection: The QuestOptimum castability and performance stabilitySelect ADC12; pursueHigh intensity and cost balanceSelect ADC10Z.
Q3: Why is ADC10Z not heat treated?
- because ofVery low magnesium content (≤0.3%)In the case of Mg₂Si, it is not possible to form sufficient Mg₂Si strengthening phases. Carrying out T6 solid solution treatment not only fails to enhance the strength significantly, but may also lead to blistering due to the expansion of internal pores. Therefore, the performance of ADC10Z is completely dependent on the as-cast organization, and the production process is simple and cost-controlled.
Q4: How is the corrosion resistance of ADC10Z? Does it need surface treatment?
- mediocre. Higher copper content (2.0-4.0%) makes it susceptible to galvanic corrosion in humid environments. For use outdoors or in wet environments, theSurface protection is mandatoryThe product can be used in a wide range of environments, such as painting, electrophoresis, anodic oxidation (with grayish film), etc. Indoor dry environment can not be treated.
Q5: What is the welding repair performance of ADC10Z?
- Lower middle. Higher copper content, welding thermal cracking tendency is more obvious. Argon arc welding filler welding, need to bePreheating (150-200°C)The choice of suitable aluminum-silicon-copper welding wire, post-welding forstress reliefThe following are some examples of the types of welds that should be used. For important load-bearing parts, filler welding should be avoided as much as possible.
Q6: What is the cutting and machinability of ADC10Z?
- general. Higher silicon content (7.5-9.51 TP3T) forms hard silicon particles that cause abrasive wear on the tool. Good results can be obtained using coated carbide tools with higher cutting speeds and moderate feeds.
