C51900 is a copper tin phosphorus alloy with high corrosion resistance, fatigue resistance, magnetic resistance, easy brazing, and good processing performance.
This material is widely used in the production of elastic components, wear-resistant and anti magnetic parts in precision instruments and meters.
C51900 can be used for producing fine-grained phosphorus copper strip products.
And C51900 (C5191/QSn6.5-0.1) has successfully mass-produced hot-dip (physical electroplating) products with tin layers of 1-6μm is acceptable.
