I recently bought a pair of ringspun lucky brand jeans and they feel softer than my other jeans, that's about itWhat is the difference? Are they higher quality? How do I care for and launder them? I've been looking online for info about ringspun jeans, but I can't find anything.
Check both of the heads to make sure they are straightThe cast iron heads need to be checked for cracks, magnafluxing the heads is the term usedThe aluminum heads need to be pressure tested for cracksUse a fricken magnet if you can't just look at the heads and tell!
The way I remember this is The RICH guy gives electrons to SAVE the POOR guyRich being higher redox potentialSince Cast Iron has the higher redox potential, it will give up its electrons before Aluminum does and corrode firstFurthermore when Al is submersed in water, it will form a passivation layer and will not corrode easily Cu/Zn/Al/Cr all have this propertyIncidentally, Chromium is what gives Stainless Steel its corrosion resistanceSince SS is made of mostly Iron and at least 6% Cr.
