N20 engine part for the F30
I read some information about the new N20 engine and I have a question about the metal Al used in making the crankshaft. I just wonder what Al alloy they used and are this alloy's shearing strength strong enough to stand this explosive force. How durable are they?

As may be seen as early as 2013, BMW uses a new Aluminum alloy designed to last no more than 4.5 years and/or 55,000 miles. Certain materials in the alloy have bond strength both time and vibration dependent; BMW metallurgical R&D has very reliably set above limits. Absent of all vibration, alloy bonds last 15 years. Severe vibration results in a 2 year service life, unlikely to be any F30's environment. BMW has established a 99% confidence level re: 4.5 yr/55k mi limits.
After either mark, whichever comes first, the alloy will deteriorate, leading to deformation and lubricant leakage.
Designed to leak engine lubricant to the plastic catch tray under the engine, sensors will illuminate an emergency red engine graphic and disable the engine until serviced & cleared by a BMW dealer with special F30 encrypted software.
The encryption code employs a previously unknown curve and non-linear hash code that cannot be broken by any known decryption technique. You must take it to a BMW dealer.
Rest assured that your new ride is safe during the warranty period. A chemical alloy refresh is applied if, and only if, a BMW approved extended warranty is purchased, or the unit is CPO'd. Without warranty protection, however, you are certain to encounter severe penalty.

The crankshaft is iron (forged). The block is aluminum.

Laugh if you will, Mykatie, but take the information seriously. BMW is determined to raise the bar re: performance and long term satisfaction, assured by warranty coverage, as well as mold customer expectations, a new paradigm.
A reflection, indeed a consequence, of European Socialism, BMW owner behavior is mandated by the performance carrot and malfunction stick. Thus, the desired result is assured as the bond to one's transport is nearly as strong as marriage. For those of other orientations, a new social control is there established.
As well, taking advantage of the BMW dealer network, this behavioral control is exported to other nation-states, similar to missionary work but with a solid basis in psychology.

Thanks for the link which I overlooked the details earlier. Anyway, I cannot remember where I got the wrong information about the Al alloy crankshaft. I feel more confortable now as the loading shaft is forged from C38 mod, a high strength micro-alloyed steel (not iron nor Al alloy)!
