C83600 Cored Bar (Sand Castings, Centrifugal Castings & Continuous Cast Bars)

Atlas Bronze offers C83600 Leaded Red Brass, SAE 40 in three different Methods of Manufacture. C83600 Cored Bar stock is available as either a Sand Casting (per ASTM B584), a Centrifugal Casting (per ASTM B271) or as a Continuous Cast Bar (usually up to 12 feet long, per ASTM B505). The Method of Manufacture (or how the material is made) will depend on the following criteria:

• Overall Dimensions
• Desired Quantity
• Total Number of Pounds
• Specifications Required
• Desired Lead Time

C83600 Solid Bar stock per ASTM B505, the most common red brass, is also called 85 metal or 85-5-5-5. It contains 85% copper and 5% each of tin, lead and zinc. Typical uses for red brass are:

• low-pressure valves,
• pump housings,
• impellers
• fittings

C83600 Cored Bar per ASTM B584 - Sand Casting

If your print or project calls for the Specification, ASTM B584, then the Sand Casting Method is what you would choose for your quotation. Sand Castings are generally. less expensive and significantly faster than the other casting methods. However, upon reviewing your overall dimensions, desired quantity, total number of pounds and lead time - we might suggest another Casting Method with the customer's approval.

This particular specification covers requirements for copper alloy sand castings for general applications. The components part casting may be manufactured in advance and supplied from stock. The castings shall conform to the compositional requirements for named elements specified.

Mechanical properties of copper alloys such as tensile strength, yield strength, and elongation shall be determined. The castings shall not be repaired, plugged, welded, or burned in.

Advantages:

• Casting with Fewer Impurities
• Significantly Faster Lead Time
• Special Shapes

• Possibly of impurities due to multiple casting step process & longer solidifying time
• Porosity Issues

C83600 Cored Bar per ASTM B271 - Centrifugal Casting

If your print or project calls for the Specification, ASTM B271, then the Centrifugal Method is what you would choose for your quotation. Unlike Sand Castings, a centrifugally cast component solidifies under a force often 50 to 100 times greater due to the rate of rotation of the mold.

Metallurgically the greatest benefit this provides is a finer grain structure within the microstructure of the casting. The finer the grain structure the better the combination of strength and toughness.

However, upon reviewing your overall dimensions, desired quantity, total number of pounds and lead time - we might suggest another Casting Method with the customer's approval.

• Yields a Casting with Fewer Impurities
• Finer Grain Structure yields Strength & Toughness

• Size & Shape Restrictions
• Length Limitations

C83600 Cored Bar per ASTM B505 - Continuous Casting

If your print or project calls for the Specification, ASTM B505, then the Continuous Cast Method is what you would choose for your quotation.

Continuous casting generally has less material lost than the other forms. and a higher productivity rate. This process also generally yields a superior quality of casting.

However, upon reviewing your overall dimensions, desired quantity, total number of pounds and lead time - we might suggest another Casting Method with the customer's approval.

• Less Material Lost
• Higher Productivity Rate

• Requires Large Mill Runs / higher total # of pounds

C83600 TYPICALL USES:

This material is used in a variety of applications. Typical uses for this alloys are: Valves, flanges, pipe fittings, plumbing goods, pump castings, water pump impellers and housings, ornamental fixtures small gears.
