Application:tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage. It is used to produce castings with complex shapes, clear contours and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam. Widely used in steam boilers and sea ship parts.
