    Performance Enhancement Path and Core Benefits<\/strong>
    The unique value of A360.0 lies in the malleability and balance of its performance:<\/p>\n\n\n\n

      \n
    1.

This provides designers with a flexible path for performance upgrades.<\/li>\n\n\n\n
    2. Excellent corrosion resistance<\/strong>: The very low copper (Cu) content is the fundamental reason why its corrosion resistance, especially to stress corrosion, far exceeds that of the A380\/A383 series of alloys, making it ideal for use in wet environments or on parts requiring surface preparation.<\/li>\n\n\n\n
    3. Good toughness<\/strong>: The lower copper and iron content reduces the amount of brittle intermetallic compounds, allowing for better impact absorption and ductility while maintaining adequate strength.<\/li>\n<\/ol>\n\n\n\n

                    Q2: Is it risky to perform T6 heat treatment on A360.0?<\/strong><\/p>\n\n\n\n

                      \n
                    • The risk is much lower than that of A380.0. Due to the relatively low gas content and dense organization of A360.0, the T6 treatment (solution quenching) is performedLess tendency to Blistering<\/strong>. However, the heat treatment of any die casting requires a tightly controlled process, and it is usually recommended that the T5 (artificial aging) test be carried out first, with a preference for the safer T5 if the strength is sufficient.<\/li>\n<\/ul>\n\n\n\n

                          Q4: Why does A360.0 have good casting fluidity?<\/strong><\/p>\n\n\n\n

                            \n
                          • Thanks mainly to itsSilicon (Si) Content of 9-10%<\/strong>The alloys have a low shrinkage rate and a low tendency to thermal cracking, and are located near the eutectic point, which gives the alloys excellent fluidity and the ability to fill thin walls.<\/li>\n<\/ul>\n\n\n\n

                            Q5: What is the machining performance of A360.0?<\/strong><\/p>\n\n\n\n
