What's the difference between a yellow copper coin and a H62 h63?
The color yellow copper should be yellow, the tin bronze should be deep red, and the color difference is obviously different.Material composition is much different, yellow copper does not contain tin, tin bronze containing tin is relatively high.Tin bronze is more lubricity.
But there is a big difference between the yellow copper plate and the tin bronze produced by the Jiashan Rongchang plain bearing
Yellow copper plate H62 and h63 basically no difference, from color, material composition, mechanical properties are similar
