That's a good idea. If anyone knows someone like that I will send them some shavings. All they need to do is sprinkle them in their underwear.Find somebody who is allergic to most 925 sterling silver, and rub it on their arms, whichever one makes them react is the M2.
That should work right Stacy.
Any chance they would look different when etchedM2 and M4 don’t have a difference in nickel content so these jokes don’t mean anything anyway.

always thought it was the other way around? 92.5% silver and 7.5% copper? no? thanks.Actually, it is the old white gold alloy that had about 5% nickel. They banned that alloy about 40 years ago.
Sterling is 92.5% copper and 7.5% silver. People who are "allergic" to silver are really allergic to copper. Despite what many people say, copper is a very rare allergy.
Fun fact - 14 karat yellow gold is 25% copper.
Just as a sidebar, would Ni be a good thing to have in there for knives? In theory at leastThe Zknives app is made by a knife enthusiast, it is not a perfect representation of steel chemistry requirements. The AISI spec allows a maximum of 0.3% Ni for both M2 or M4. The Zknives app shows this as simply 0.3% Ni for whatever reason with M2 and leaves it off for M4.
True. The Canadian 5 cent piece used to be about the size of a dime and made of 80% silver.Thanks for the catch. It was a typo. 92.5% silver/7.5% copper.
Coin silver (mostly used to make silverware and serving pieces) is 90% silver and 10% copper to make it harder and last longer. Some countries, like Canada used only 80% silver in their coins.
The danger with nickel additions is that it is a strong austenite stabilizer so retained austenite becomes a concern.Just as a sidebar, would Ni be a good thing to have in there for knives? In theory at least
Gotcha. Since steels like that already can have retained austenite.The danger with nickel additions is that it is a strong austenite stabilizer so retained austenite becomes a concern.
Are they still nickel? Bet they would be worth a lot more as scrap.True. The Canadian 5 cent piece used to be about the size of a dime and made of 80% silver.
In 1921 they recalled them and switched to the nickel. I bought one of the few hundred that survived with my paper route money when I was a kid. I sold it about 10 years later to buy alcohol and other essentials.
I quit collecting in the early 80s. According to Google they were 99.9 percent nickel for a range of dates up to 1981. Apparently now they are mostly steel with some nickel plating.Are they still nickel? Bet they would be worth a lot more as scrap.
