Is tin bronze the same as phosphor bronze? What is the difference
Is tin bronze the same as phosphor bronze? What is the difference.
Tin bronze and phosphor bronze are different.
Element content of tin bronze, electrolytic copper 84 ~ 97%, tin 2 ~ About 15%, there are some other trace elements accounting for about 1%, according to a certain ratio, can be used for different hardness structural parts.
Element content of phosphor bronze, electrolytic copper 98 ~ Between 99%, the phosphorus content is 1 ~ 1. About 5%, the rest of the metal content of 0. About 5%.
According to a certain ratio, it can be used as different wear-resistant structural parts.
Phosphor bronze has higher corrosion resistance, wear resistance and no spark during impact.
It is used for medium speed and heavy load bearings with a maximum working temperature of 250 ℃.
It has the characteristics of automatic centering, insensitivity to deflection, uniform bearing force and high bearing capacity, simultaneous radial load, self-lubrication without maintenance, etc.
Tin bronze and phosphor bronze contain different amounts of alloying elements.
Tin bronze is relatively more tin-containing, phosphor bronze is relatively more phosphorus-containing. There are many different brands of tin bronze and phosphor bronze. The replacement depends on the specific situation, the use environment, mechanical properties, and so on.
