    Characteristic

    1. Hardness:

       - Hardness of 7075 aluminum alloy:

    Typically ranges from 150 to 160 HB (Brinell Hardness).


       - Hardness after hard anodizing:

    Increases to approximately 60 to 70 Rockwell C (HRC).


       - Advantage:

    Enhanced surface hardness improves wear resistance and durability, prolonging the lifespan of the parts.


       - Disadvantage:

    Increased hardness may lead to reduced machinability and increased tool wear during machining processes.

    2. Corrosion Resistance:

       - Corrosion resistance of 7075 aluminum alloy:

    Good corrosion resistance in natural environments.


       - Corrosion resistance after hard anodizing:

    Further improves, offering excellent resistance to corrosion, especially in harsh environments such as marine or industrial settings.


       - Advantage:

    Hard anodizing creates a protective oxide layer that prevents corrosion and increases longevity.


       - Disadvantage:

    Hard anodizing may introduce micro-cracks in the surface, potentially compromising corrosion resistance in certain conditions.



    3. Surface Finish:

       - Surface finish of machined 7075 aluminum parts:

    Typically Ra 0.8 to 1.6 micrometers.


       - Surface finish after hard anodizing:

    Maintains the original surface finish of the machined part.


       - Advantage:

    Hard anodizing preserves the aesthetic appearance of the parts while providing additional protection against wear and corrosion.


       - Disadvantage:

    Hard anodizing may result in slight dimensional changes, requiring adjustment in the machining process to achieve precise tolerances.



    4. Tensile Strength:

       - Tensile strength of 7075 aluminum alloy:

    Approximately 572 MPa (83,000 psi).


       - Tensile strength after hard anodizing:

    Remains largely unchanged.


       - Advantage:

    Retention of high tensile strength ensures structural integrity and load-bearing capacity in applications requiring strength and durability.


       - Disadvantage:

    None significant, as hard anodizing does not significantly affect tensile strength.



    5. Dimensional Stability:

       - Dimensional stability of machined 7075 aluminum parts:

    High precision and dimensional accuracy.


       - Dimensional stability after hard anodizing:

    Minimal dimensional changes, typically within ±0.002 inches.


       - Advantage:

    Hard anodizing provides a uniform coating thickness, maintaining tight tolerances and ensuring part-to-part consistency.


       - Disadvantage:

    Process variations or improper sealing of the anodized layer may result in dimensional inconsistencies.
