The tin increases the strength of the alloy and gives good corrosion resistance in marine environments and zinc is added to act as deoxidant and assist with pressure tightness. Bearings need good alignment wstm mating parts and adequate lubrication. These moderate strength alloys exhibit good corrosion resistance when submerged in liquids or chemicals.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Rounded Limit for Observed or Calculated Value.

They withstand corrosion in many environments including seawater, chlorides, and dilute acids. This cast bronze material is often found in landing gear bushings, pumps, valves, bearings, gears, gear blanks, and many other industrial applications.

These requirements apply to the casting specifications to the extent referenced therein. Cast BronzeStock Alloys. Applications range from bearings and gears to plumbing goods and intricately shaped pump and valve component manufacturing. Already Subscribed to this document. C offers a combination of engineering properties, such as high strength, excellent fatigue, good bearing properties, coupled with corrosion resistance.

Silicon Bronze Castings These moderate strength alloys exhibit good corrosion resistance when submerged in liquids or chemicals. These alloys not only have high tensile and yield strength, but can operate under very high loads and speeds which makes them a great alloy for your bearing needs.

Our foundry pours the following bronze alloys:. As the voice of the U. Stainless Steel Condition A. This standard is not included in any packages. C can be joined by soldering, but brazing must be preformed so as to avoid strain and cooled slowly to avoid problems with hot shortness. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Manganese Bronze Castings, The strongest of all cast copper alloys, these alloys are used mainly for heavy duty mechanical products requiring moderately good corrosion resistance at a reasonable cost. They 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 applications as well as moveable bridge components.
