List of products
Al-Cu-Si alloys
- AC2A.1
- AC2B.1
Features
Al-Cu-Si alloys have high tensile strength and are excellent for general use.
Applicable components
Cylinder heads and other automobile parts, etc.
Al-Si-Cu alloys
- AC4B.1
Features
Al-Si-Cu alloys have excellent tensile strength and castability, and their tensile strength exceeds 300 MPa after heat treatment.
Applicable components
Cylinder heads and other automobile parts, etc.
Al-Si alloys
- AC3A.1
Features
Al-Si alloys have excellent castability, corrosion resistance, and toughness, but their strength and proof stress are low. They are suitable for items with complex shapes and thin items.
Applicable components
Cases, cover parts, etc.
Al-Si-Mg alloys
- AC4A.1
- AC4C.1
- AC4CH.1
Features
Al-Si-Mg alloys have excellent castability, corrosion resistance, strength, and toughness. In particular, AC4CH exhibits extraordinary elongation after modification and heat treatments, as it is a standard that limits impurities.
Applicable components
Wheels, line hardware, etc.
Al-Mg alloys
- AC7A.1
Features
Al-Mg alloys have the best corrosion resistance and high toughness. However, their castability is poor, and solidification shrinkage and cracking occur easily.
Applicable components
Line hardware, shipbuilding parts, etc.
Al-Si-Ni-Cu-Mg alloys
- AC8A.1
- AC8B.1
- AC8C.1
Features
Al-Si-Ni-Cu-Mg alloys have excellent thermal resistance, good wear resistance and low thermal expansion coefficient. Their tensile strength is also high.
Applicable components
Automobile pistons, pulleys, shaft bearings, etc.
