Brass Bar News: Tin bronze is characterized by bronze containing 3%-14% tin, and other elements such as phosphorus, zinc and lead are often added. It is the earliest alloy used by human beings, and it has been used for about 4000 years. It is corrosion-resistant, wear-resistant, has better mechanical and technological effects, and can be well welded and brazed, sparks are produced when attacked. It is divided into processing tin bronze and casting tin bronze. The tin content of tin bronze used for pressure processing is less than 6%-7%, and that of cast tin bronze is 10%-14%. The rare brands are QSn4-3, QSn4.4-2.5, QSn7-O.2, ZQSn10, ZQSn5-2-5, ZQSN6-6-3, etc. Tin bronze is a non-ferrous metal alloy with the smallest compression rate. It can be used to produce castings with large shape, outside and low air tightness. Tin bronze is abnormally resistant to corrosion in atmosphere, fresh water, fresh water and steam, and is widely used in steam boilers and marine machinery. Phosphorus-containing tin bronze has excellent mechanical properties and can be used as a wear-resistant and elastic machine for high-precision working mothers. Lead-tin bronze is rarely used as wear-resistant machine and sliding bearing. Zinc-tin bronze can be used as high air tightness casting.
