Gray iron is vary brittle with very little tensile strength while nodular iron is stronger and ductile iron has better tensile strength.65 350 TI CONV 67 J56 435 CONV,67,390/AIR CONV,70 454/air CONV,

Re: Opinions on Lone Star versus CSSB calipers?
[QUOTE=Mark Francis (30800);902966]Adding on to what Joe has described – and having worked in several foundries, I was always fascinated at what a crude and filthy process casting is (or at least, used to be). However, as crude as it was, the chemistry and metallurgical alloy results were amazingly controlled and QA’d.
This site has text providing a good overview of what Joe has described – enumerating the different types of “cast irons” and their associated characteristics. Skip to the end for 2 minute video if you don’t need all their text details…

The site above mentioned “nodulizing elements”, but they didn’t tell you what some of them are (magnesium and other rare earths)….
The quick video link below shows how magnesium is added to a single ladle of grey iron to convert it to ductile, nodularized(sp?) iron. IIRC, in automotive specialty foundries I have been in (40 years ago in large-scale, 24-hour casting operations), these elements are added as part of the cupola “charge”, rather than being added at the end in ladles as shown here…either way, the chemistry/metallurgical results are probably the same…
And finally, the first part of this one very clearly demonstrates how resistant to cracking ductile iron can be!
As for the remainder of this video, I’d say “Don’t Try This at Home!”
Thanks for the links. It may seem crude to you but sand casting is a very economical and practical way to cast metals. The basic process has ben used for thousands of years. Foundries have come a long way since I started in the pattern /foundry business in 1964 in cleaning up the dust & dirt from the sand & smoke from molten metal.
As to what makes the difference in the different types of iron as i was told id how the carbon/ graphite molecules line up. Gray iron the molecules are gust randomly spread through the iron where the others to different degrees are lined in strength rows to increase tensile strength.65 350 TI CONV 67 J56 435 CONV,67,390/AIR CONV,70 454/air CONV,
