For people that think china metal is as good as American metal I have a story for you.
I work as a Reliability Engineer for a medical device manufacturer.
We were doing some reliability tests and noticed some weird failures that we couldnt explain and had never seen before.
We sent the parts to our metallurgical lab and had them run the tests on the parts to verify the alloy was what is was supposed to be.
Come to find out the alloy was "dilluted" with cheaper the cheaper metals.
We tracked the lot of the material to mcmaster-carr and sure as can be they bought the material from China. We now demand made in the USA material and expect a certification when the components arrive.
We havent had a failure since.
