CEX Advantage: CEX can use advanced manufacturing techniques to produce Al-Cu components with high precision and good surface finish, which can meet the requirements of critical industries.

Aluminum-Magnesium Alloys (Al-Mg)

Alloy Examples: 5083, 6061, 7075

Material Characteristics: Al-Mg alloys have light weight and high strength-to-weight ratios.

They have good corrosion resistance and weldability, which make them widely used in marine, aerospace and automotive industries for structural applications.

CEX Advantage: CEX can use optimized casting processes to produce Al-Mg components with high mechanical properties and accurate dimensions, which can meet the requirements of different working conditions.

Aluminum-Zinc Alloys (Al-Zn)

Alloy Examples: ZA-27, ZA-8, 7075

Material Characteristics: Al-Zn alloys have high strength, hardness and dimensional stability.

They are widely used in applications requiring high temperature performance, fatigue resistance and stress corrosion cracking resistance.

CEX Advantage: CEX can control the casting parameters and alloy composition precisely to produce Al-Zn components with high mechanical properties and good surface conditions, which can meet the requirements of demanding engineering applications.
