ADC-6

Aluminum DIe Casting Alloy (ADC) - 6

Die casting is a high-pressure metal casting process where molten aluminum is forced into a steel mold under pressures ranging from 10 to 175 MPa. The ADC series alloys are standardized under JIS H 5302 and are specifically formulated for this process, requiring high fluidity, low shrinkage, and good release from the die.


ADC-6 is a low-silicon, magnesium-modified aluminum die casting alloy known primarily for its excellent corrosion resistance. Unlike the more common ADC-12, it contains virtually no copper, which makes it significantly more resistant to electrochemical corrosion. This alloy is one of the few die casting grades considered suitable for decorative anodizing.


Key Characteristics

•      Excellent corrosion resistance — the near-zero copper content prevents galvanic corrosion

•      One of the few die casting alloys suitable for protective and decorative anodizing

•      Moderate mechanical strength compared to copper-bearing grades

•      Good surface finish capability

•      Lower fluidity than ADC-12, requiring careful gating design


Typical Applications

•      Marine hardware and fittings

•      Automotive exterior trim and decorative parts

•      Electrical connectors and enclosures

•      Consumer appliance housings requiring corrosion resistance

•      Architectural hardware

ADC-12

Aluminum Die Casting Alloy (ADC) - 12

ADC-12 is the most widely used die casting aluminum alloy in the world. Its combination of high silicon content (near the eutectic point) and copper additions gives it outstanding castability, excellent fluidity, and good mechanical properties in the as-cast state. It is the workhorse alloy for high-volume automotive and industrial die casting worldwide.


Key Characteristics

•      Excellent die-filling ability due to near-eutectic Si content — preferred for thin-wall and complex geometries

•      Very good dimensional stability and low shrinkage during solidification

•      Good machinability in the as-cast condition

•      Cu addition provides solid solution strengthening and age-hardening potential

•      Not suitable for anodizing due to Cu content causing discoloration

•      Moderate corrosion resistance — requires surface coating in aggressive environments

•      Higher Fe content tolerance reduces die soldering tendency


Typical Applications

•      Automotive engine blocks, transmission housings, and valve bodies

•      Electronic housings and heat sinks

•      Industrial machinery components

•      Consumer electronics and power tool housings

•      Hydraulic pump and valve bodies

AC2B

Sand & Gravity Casting Aluminum Alloys - AC2B

AC2B is a general-purpose Al-Si-Cu casting alloy offering a well-balanced combination of castability, machinability, and mechanical strength. It is one of the most economical alloys in the AC series and is widely used for non-critical structural castings.


Key Characteristics

•      Good general-purpose castability in both sand and permanent mold

•      Good machinability due to Cu and Si content

•      Moderate corrosion resistance — not for aggressive environments without coating

•      Can be used in as-cast (F) or annealed (O) condition

•      Cu provides some age-hardening response if solution treated


Typical Applications

•      General machinery and pump bodies

•      Household goods and cookware molds

•      Electric motor housings

•      Brackets, covers, and non-structural components
