Suitable for mass production of die-casting, complex structural housings, medium-strength metal parts, thin-walled aluminum alloy parts, and mass production of industrial components.
ADC12 Aluminum Alloy is a commonly used aluminum-silicon-copper cast aluminum alloy material for die casting, featuring excellent flowability, formability, dimensional stability, and mass production efficiency. It is very suitable for manufacturing aluminum alloy die-cast parts with complex structures, thin walls, and large batches, commonly used in automotive parts, electronic and electrical housings, mechanical housings, heat dissipation structural components, hardware parts, and industrial equipment components. Compared to materials like CNC 6061 Aluminum Alloy and 7075, ADC12 is more suitable for mass production by die casting, rather than high-strength precision cutting.
By focusing on application scenarios, boundaries of advantages, and non-recommended scenarios, it helps sales, customer service, and quoting staff quickly determine whether the material meets current part requirements.
It has good flowability, is suitable for die casting molding, complex structures, thin-walled parts, high mass production efficiency, good dimensional stability, relatively controllable material costs, and can be processed with sandblasting, painting, powder, electrophoresis, shot blasting, and machining post-processing.

The following parameters come from product information and material knowledge fields, used for design review, quotation communication, and preliminary judgment before material selection.
| Material positioning | Suitable for mass production of die-casting, complex structural housings, medium-strength metal parts, thin-walled aluminum alloy parts, and mass production of industrial components. |
|---|---|
| Precision performance | ADC12 die-cast parts have good repeatability in mass production, suitable for complex structures and medium-precision parts. Actual accuracy is affected by mold accuracy, die-casting equipment, material shrinkage, part dimensions, wall thickness uniformity, demolding angle, post-processing, and surface treatment. Key assembly surfaces, positioning holes, threaded holes, sealing surfaces, and high-precision hole positions usually require die casting before CNC finishing. |
| Dimensional tolerances | The standard dimensional tolerances for ADC12 die-cast parts can be referenced ± 0.10mm-±0.30mm. Small structural parts and mold controls with good control are easier to stabilize dimensions; Large components, thin-walled parts, complex structural parts, and multiple post-processing parts may reach ±0.30mm-±0.80mm or higher. This value is a standard reference range and does not guarantee absolute tolerances for all structures; key dimensions are recommended to be guaranteed through post-processing. |
| Minimum Wall Thickness | For small ADC12 die-cast parts, the local wall thickness can be referenced as 1.0mm-1.5mm, but it is not recommended to use large areas with overly thin wall thickness. Walls that are too thin easily cause insufficient filling, cold insulation, deformation, insufficient strength, and coating defects. The load-bearing structure, mounting positions, and large housing should be appropriately thickened. |
| Recommended wall thickness | Standard die-cast shells and structural components are recommended with wall thicknesses of 2.0mm-3.0mm; small thin-walled shells can be designed to 1.5mm-2.0mm depending on structure and mold capacity; mounting bases, screw posts, reinforcing rib roots, and load-bearing positions are recommended 2.5mm-4.0mm, and stress concentration is reduced through fillet and transition structures. |
| Minimum aperture | The recommended hole size for die casting is no less than 1.5mm-2.0mm. Smaller holes, deep holes, precision holes, and threaded holes are recommended to be achieved through post-processing. Mold core-pulling holes need to consider core-pulling strength, demolding angle, hole depth, and mold lifespan. It is recommended to reserve machining allowance for positioning holes, sealing holes, threaded bottom holes, and assembly holes. After die-casting, drilling, reaming, or tapping holes is recommended. |
| Assembly clearance | For ordinary die-cast parts, it is recommended to reserve 0.15mm-0.40mm on one side; for unmachined die-cast surface assembly, it is recommended to appropriately increase the gap; for movable fits, it is recommended to reserve 0.30mm-0.60mm on one side. If subsequent painting, powder spraying, electrophoresis, or chemical treatment is needed, additional consideration should be given to coating thickness to avoid over-tightening or scratching the coating. |
| Detailed performance | ADC12 die casting is suitable for achieving rib positions, column positions, steps, mounting seats, signage, shallow textures, and complex shell structures. Fine text, logos, and decorative textures should avoid being too shallow or too fine; it is recommended that raised or recessed details should be no less than 0.3mm-0.5mm. High-precision appearance textures, precise markings, and decorative effects can be achieved through mold etching, spraying, screen printing, laser marking, or post-processing. |
| Surface effect | The original die-cast surface of the ADC12 is usually silver-gray or light gray metal, with visible parting lines, ejector pin marks, flow marks, or slight die-casting textures. After shot blasting and sandblasting, a relatively uniform matte gray surface can be obtained; After painting, powder spraying, or electrophoresis, more stable appearance colors and protective effects can be achieved. If you pursue high-end natural metal or anodized texture, ADC12 is usually not as suitable as 6061 aluminum alloy. |
Based on material characteristics and suitable product ranges, customer needs are broken down into easier application directions to determine.
Automotive die-cast parts, motor housings, electronic and electrical appliance housings, communication equipment housings, mechanical equipment housings, lighting fixture housings, radiator housings, pump housings, valve housings, brackets, mounting seats, hardware accessories, small structural parts, batch aluminum alloy functional parts, die-cast exterior parts.
Suitable for mass production of die-casting, complex structural housings, medium-strength metal parts, thin-walled aluminum alloy parts, and mass production of industrial components.
The biggest feature of ADC12 is its excellent die casting fluidity, making it suitable for one-time forming of complex shapes, rib positions, hole positions, thin-walled housings, and batch structural parts. It can be quickly formed in molds, suitable for mass production, and has a higher cost per piece after mass production. However, ADC12 contains elements like silicon and copper, so its corrosion resistance and anodized appearance are generally inferior to wrought aluminum alloys like 6061 and 5052, and its strength and toughness are not suitable as substitutes for high-strength aluminum alloys or steel parts.
Based on wall thickness, hole position, assembly clearance, dimensional tolerances, and material usage risks, determine in advance whether the part structure is suitable for ADC12 Aluminum Alloy.
Post-processing of ADC12 Aluminum Alloy affects appearance, dimensions, hole position, assembly clearance, and usage validation results, and should be explained in advance during quotation, DFM review, and sample confirmation stages.
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining, coating, and trial assembly allowances.
For common issues such as threads, snaps, strength, temperature resistance, and weather resistance, identify in advance whether the material needs to be replaced or if another processing method should be used.
When customer demand exceeds ADC12 Aluminum Alloy material boundaries, it is necessary to combine strength, temperature resistance, toughness, long-term stability, and mass production goals to promptly recommend alternative materials or processing technologies.
If CNC precision machining and better anodizing results are needed, 6061 aluminum alloy can be chosen; If higher strength is required, 7075 aluminum alloy or 2A12 aluminum alloy can be chosen; If sheet metal bending and corrosion-resistant casing are needed, 5052 aluminum alloy can be chosen; If higher corrosion resistance and long-term outdoor stability are required,316L Stainless Steel or TC4 Titanium Alloy (Ti-6Al-4V) can be chosen; For small-batch verification, photosensitive resin, nylon, CNC aluminum alloy, or metal 3D printed samples can be chosen.
If customers need to mass-produce complex aluminum alloy housings, brackets, housings, or medium-strength structural components, the ADC12 is the appropriate choice. If the customer is still in the prototyping stage, with limited quantities or structures not yet finalized, it is recommended to first verify the structure using CNC aluminum alloy, 3D printing, or soft mold samples, and then proceed to die casting and mold making. If customers require high strength, high toughness, high corrosion resistance, or high-end anodized appearances, priority should be given to 6061, 7075, 5052, stainless steel, or other materials.
