Main features |
|
QSn4-3 |
Tin-bronze containing zinc feature high wearability,elasticity and diamagentism;it can be processed status,it boasts high machiability,easy for welding and brazeweiding;high corrosion resistance under atmosphere,fresh water.seawater. |
|
It can be used to make spring(flat spring,round spring)and other elastic component,anti-corrosive and wear-resistant component of chemicat equipment(such as bushing,round plate,bearing),and anti-magnetic scraperin paper-making industry. | |
|
QSn4-4-2.5 QSn4-4-4 |
Tin-bronze containing zinc and aluminum feature high machiability and frictionreduction property;easy for welding and braze welding;high corrosion resistanceunderfrdsh water:it can only be processed under pressuer in cold status:it containszinc soitis liable to become brittle under heat processing. |
|
it is used to make bearing,edge-folded axial sleeve,busing,round plate and inner padof bushing working underfriction;QSn4-4-4 can work at the temperature lowerthan 300℃.it is a king of tin-bronze with high heat strength. |
