Bronze without tin does not contain in its composition scarce tin. They can serve not only as substitutes for tin bronzes, for its anticorrosion, industrial and mechanical properties without tin bronze is often superior. Bronze without tin are beryllium, aluminum, manganese, etc., depending on the main alloying element. Bronze tin-free, processed under pressure, meet GOST 18 175−78. This standard applies to bronze without tin pressure treated and designed for the production of semi-finished products and billets.
