C922oo Alloy
C922 alloy’s versatility makes handling casting projects easier. This high-quality leaded tin bronze alloyed copper-based casting material has several properties that make it ideal in various applications.
What Is C92200 Leaded Tin Bronze Alloy Made Of?
Several chemicals make up the tin bronze alloy known as C922 or C92200.
These chemical elements represent the composition based on its minimum and maximum values:
- Copper (Cu): Its minimum composition is 86% and its maximum is 90%. It is the main material used to produce the C922 alloy.
- Nickel (Ni): Includes carbon monoxide in its 1% maximum composition capacity.
- Lead (Pb): Comprised of a minimum composition of 1% and a maximum of 2%.
- Zinc (Zn): Includes a minimum of 3% and a maximum of 5% zinc contribution.
- Tin (Sn): Tin contributes a minimum of 5.5% and a maximum of 6.5%.
- Iron (Fe): Constitutes a maximum of 0.25% in C922 alloy.
Other elements with less than 1% contributions include phosphorous, aluminum, sulfur, antimony and silicon.
Properties of C922 Navy M Tin Bronze Alloy
Leaded tin bronze alloy has various properties suitable for high tensile strength casting applications. Some of its main physical properties include:
- Melting points: Reaches liquidus at 1810 degrees Fahrenheit and solidus at 1518 degrees Fahrenheit
- Density: A 0.312 pound-to-cubic-inch density at 68 degrees Fahrenheit
- Conductivity: According to IACS, electrical conductivity is 14% and thermal conductivity is 40.2, both at 68 degrees Fahrenheit
- Coefficient of thermal expansion: The coefficient is 10 between 68 degrees Fahrenheit to 572 degrees Fahrenheit
- Tension elasticity: 14000 ksi
- Incipient melting: 600 degrees Fahrenheit
Navy M tin alloy’s casting characteristics vary. The specific attributes are distinguished by their level:
- Yield: Medium
- Drossing: Low
- Fluidity: Medium
- Gassing: Medium
- Section size effect: High
This alloy type’s fabrication properties make it most suitable for soldering and brazing, and it has a machinability rating of 42. However, it is unsuitable for oxyacetylene welding, gas-shielded arc welding and coated metal arc welding.
