Japanese Carmakers Say Aluminum from Kobe Steel Is Safe
Honda, Mazda and Toyota say hoods and other exterior components made with improperly inspected sheet aluminum supplied by Kobe Steel Ltd. are safe.

Kobe admits it has been falsifying quality data about its aluminum, iron, steel and copper products for 10 years. The materials have been used by some 500 companies worldwide in everything from cars and planes to trains and computer discs.

Generally, when OEMs produce aluminum engine blocks (aluminum rather than cast iron because cast iron weighs like cast iron), they insert sleeves into the piston bores—cast iron sleeves.
