âSpoons come in many different sizes and are not precise enough to measure a childâs medication,â said pediatrician Ian Paul, MD, FAAP, lead author of the policy statement. âFor infants and toddlers, a small error â especially if repeated for multiple doses â can quickly become toxic.â.
Copper and bronze do not contain any iron, and only iron can rust (because rust is defined as iron oxide, a compound of iron and oxygen); so the answer is that steel will rust the fastest and copper and bronze will never 'rust'. But, yes, copper and bronze do tarnish, they do corrode.
I think K is the most common. Looks like stainless steel and machines about the same. These two are the only copper/nickel alloys that are called Monel. There are a lot of other copper/nickel alloys. Monel has more nickel than copper. When the copper content gets higher the color changes toward copper. Probably at least 400 alloys of copper with nickel, aluminum, zinc, tin, magnesium with various names but there are only two that are called Monel as far as I know. 04-28-2008, 03:46 PM #20.
