Bronze Casting Alloy: Tin Bronze C90300
Erie Bronze & Aluminum is a Non-Ferrous Copper Alloy Sand Casting Foundry specializing in copper and bronze alloy castings. Serving numerous industries, we cast a variety of non-leaded bronze alloys, including Tin Bronze 90300, or 903. Tin bronze alloy 903 is known for excellent soldering and good brazing capabilities, and fair machinability. Components of this alloy are capable of accepting shock and impact loads, but with reduced surface speeds, which makes them an excellent choice for high strength bushing and bearing as well as moveable bridge components. Tin bronze alloys, such as C90300, are typically found in:
High-strength bushings & bearings
- Valve bodies
C90300 tin bronze sand castings are used for fixed and expansion bearings, where movement is slow or intermittent or where heavy loads are present, such as turntables for bridges and heavy construction equipment.
Choosing Tin Bronze C90300 for Your Bronze Alloy Sand Castings
Erie Bronze & Aluminum produces Tin Bronze 903 to meet casting material specifications:
- ASTM B 584: Standard Specification for Copper Alloy Sand Castings for General Applications
- ASTM B 763: Standard Specification for Copper Alloy Sand Castings for Valve Applications
- SAE J461: Used for cast copper alloys to maintain the electrical and thermal conductivity properties, mechanical properties, yield strength, fatigue characteristics, formability and machinability of these alloys.
- SAE J462: Focuses on Cast Copper Alloys used in Aerospace, Automotive, and Commercial Vehicle Industries
Tin Bronze 903 characteristics give it an edge over other metals and metal alloys which makes it a versatile metal alloy for numerous fabrication practices.
