    in case you missed it...

    K1045 is a Steel Alloy (Carbon, Manganese) Typical uses include gears, shafts, axles, bolts, studs, and machine parts.

    Just to reiterate: aluminum and alloy are NOT the same thing. There are Aluminum alloys, Steel alloys and many other types of alloys.
    There are various grades of so called "Air-Craft" alloy commonly used in aero-space industry, with different properties depending of purpose.

    no cut off date guys......

    im getting 4 pairs made up AFTER my own pair, which will be the test fit.....pics.....blah blah

    then they will sit at the CNC shop till they are needed ie when someone hands over $$

    we are keeping the drawings too so they can be loaded into the machine at any stage in the future if we want to do a second run

    Well the alloy rotor hats on the sls seem to hold together without shattering/melting or deforming.

    for 3rd time: alloy ≠ aluminum *&* rotor hat ≠ axle hub

    The "alloy" material used my MB, Porsche, Ferrari, etc for rotor hats on ceramic compostite brakes, and other suppliers such as AP, Alcon, Brembo, etc of high performance/motorsport brake set-ups, is not really the discusssion topic here - namely the HUB which rotates on the stub axle, to which the brake disc and wheel bolts to.

    Out of interest do you happen to know the specific alloy type/grade used by MB for rotor hats on AMG SLS? or the reasons why an alloy hat is used over a 1-piece disc? (clue part of the reason CCB are a 20-grand option is the manufacturing process, each disc is balanced to hat with weighted fastners)
    a) reduced rotating mass and unsprung weight.
    b) less heat transfer-soak to hub and bearings.
    c) nature of carbon/ceramic compound not suitable for mounting assembly itself.
    d) all of above.
    e) other?

    yes, got it this time Karl

    i can understand why you would want these hubs if you wanted the +10 track/brake clearance.

    but i only want them if theyre significantly lighter. i dont know the properties of K45 so..?

    1045 is a medium tensile steel. not quite as good as 4140 but alittle better than normal mild steel.
    it's not really an amazingly awesome grade of steel.

    im not sure on the weight though, but i can't see it being lighter than mild steel.
