There is an aluminum hardcoat surface treatment called Akadizing from Lovatt Processes that would resolve many issues I've seen mentioned in various posts. An aluminum part has successfully replaced a steel drive shaft seal assembly for an Indy car by outperforming the steel unit in crash testing. It also has incredible hardness (9.2 - 9.7 on the Mohs scale) and corrosion resistance. They offer to do test parts for interested parties so testing can be done to verify the benefits and have many test reports available.
Yes, I'm affiliated with the company and am trying to spread the word on this incredible metal treatment that has been available for 40 years, but not heavily marketed. Akadized parts are on the space shuttles, stealth aircraft, motorcycle clutches,and numerous other challenging applications. Their web site is www.lovattprocesses.com.
Ann, thanks for the clarification. So far I didn’t think in that angle, so what I understood is as an effort to minimize the engine load, companies are planning to replace the heavy weight metallic parts with mild weight materials and in continuation to that effort they are using Aluminum wheels instead of steel, am I right.
