Is it zinc or aluminium?
Any simple test for aluminium vs zinc?

 93 forum posts 11 photos | A word of caution when heating Zinc. I did just a few minutes TIG-welding a joint in 1" Zinc-plated steel tube. (I did not know it was plated!) About 10 hours later I got a serious blood pressure fall. I was outside, and had to hold on to a tree, even when laying flat on the ground. My balance was non-existing, and the world was spinning madly. This lasted for 2 days. It took a week before I could walk with confidence on a flat floor. Zinc-poisoning is no joke! |

| 89 forum posts 3 photos | The simple answer is that zinc is almost 3 times heavier than aluminum. By practicing on sample bits (by comparison), I should be able to detect which is which. Since zinc density is close to iron, that might help with the learning process. Once this skill is acquired, no need to have access to acids or other special equipment. Thanks to everyone for their assistance. Paul |
