Ship stern shaft sleeve
Classification:
Tin bronze is a non-ferrous metal alloy with small casting shrinkage, which can be used to produce castings with complex shapes, clear contours and low air tightness requirements. Tin bronze is very corrosion resistant in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision machine tools. Leaded tin bronze is commonly used as wear parts and sliding bearings. Zinc-tin bronze can be used as high gas-tight castings.
