Cracks in an aluminum head or block, on the other hand, are much more difficult to repair by pinning because aluminum is a softer metal than cast iron so the pins and plugs can’t achieve as much “bite” as they do in an iron casting.

WebOct 27, 2024 · We educate customers on leak-rate theory and how aluminum-porosity leaks are different compared to mechanical-fastener or welded-joint leaks. It takes time, but eventually there is an ‘aha moment’ when the customer realizes that a cast-aluminum-housing porosity leak is different than a weld leak or rotating-seal leak. ... Porosity may take on several forms from interconnected micro-porosity, folds, and inclusions to macro porosity visible on the part surface. The end result of porosity is the creation of a leak path through the walls of a casting that prevents the part from holding pressure. See more Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%.
