Product Details
Product details:
Product Model: almgcu03
Product features:
1. Low density—adding just 1% lithium reduces the density by 3%.
2. Featuring high specific modulus and high specific strength, it replaces conventional high-strength aluminum alloys, offering a 6% increase in elastic modulus and a 15%-20% improvement in stiffness.
3. Superplastic Forming Performance
4. Excellent corrosion resistance
5. Excellent castability, hot working capabilities (rolling, forging, extrusion), weldability (laser welding, friction stir welding), and machinability.
