Aluminium Machining

    Aluminium is a metal which is lightweight, durable, soft, malleable, and ductile. Depending on its surface roughness, its appearance can be anything from a dull grey to silvery.

    Aluminum Facts:

    • Does not ignite easily
    • Tin-white metal
    • Melts at 640 degrees
    • Is very light, a density of 2.68
    • Is non-magnetic
    • Is strong and stiff
    • Creates a fine surface finish
    • Can be rolled into thin foil with constant annealing
    • Is a good conductor of electricity and heat

    Aluminium alloys are sensitive to high temperatures which range between 200 °C and 250 °C. At this temperature, they may lose some of their strength.

    However, strength can be increased at subzero temperatures. Because of this, aluminium alloys are perfect for low-temperatures.

    3D Machining

    Aluminium alloys are perfect for 3D Machining due to their good strength-to-weight ratio, low density, and high thermal and electrical conductivity. They also offer natural corrosion resistance and am able to be anodized. 

    Types of CNC Aluminum

    Aluminium 6061

    • The most popular aluminium alloy
    • Corrosion resistant
    • Non-magnetic

    Aluminium 7075

    • Aerospace-grade material
    • High strength
    • Non-magnetic

    Aluminium 5083

    • Strain hardening alloy with excellent corrosion resistance
    • Chemical resistant
    • Non-magnetic

    Aluminium 6082

    • Similar to 6061, but with higher tensile strength
    • Corrosion resistant
    • Non-magnetic

    Aluminium anodise

    Anodising aluminium helps to reserve the metal finish and the natural texture, lustre, and beauty. An anodized coating is durable, hard, and will never peel. Under normal conditions, it will also never wear through.

    Aluminium anodise if a process which employs electrolytic oxidation of the aluminium surface. This produces a protective coating and finishes made of oxide.

    • The coating is resistant to abrasion and corrosion
    • It consists of hydrated aluminium oxide
    • Coatings conventionally are 01. to 1.0 mil thick
    • Coatings are usually transparent. However, they can also be colored
