4、 Characteristics
(1) Mechanics and Processing Characteristics
Good casting performance: It is a non-ferrous metal alloy with low casting shrinkage, which can be used to produce castings with complex shapes, clear contours, and low requirements for airtightness.
Higher mechanical properties: It has higher mechanical properties such as strength and toughness, and overall has higher performance than ordinary copper. Its strength and toughness, physical properties, chemical composition, biocompatibility, and process performance are all reflected.
Easy to process: This alloy is easy to cut, has good brazing and welding performance, small shrinkage coefficient, and is non-magnetic. Bronze bushings, shafts, etc. can be prepared using wire flame spraying and arc spraying.
(2) Corrosion resistance
It is highly corrosion-resistant in the atmosphere, seawater, freshwater, and steam, and is widely used in the production of components such as steam boilers and marine ship parts that require corrosion resistance.
