C83600 Rectangle / Plate (Sand Castings & Continuous Cast Bars)

Atlas Bronze offers C83600 Leaded Red Brass, SAE 40 in two different Methods of Manufacture. C83600 Rectangle stock is available as either a Sand Casting (per ASTM B584) or as a Continuous Cast Flat 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 Rectangle / Plate is 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 for low-pressure valves, pump housings, impellers and fittings.

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.

C83600 Rectangle 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.

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.

Some Advantages of C83600 Rectangle Sand Casting:

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

Some Disadvantages:

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

C83600 Rectangle 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 of casting and a higher productivity rate. This process also generally yields a superior quality casting.

Some Advantages:

• Less Material Loss
• Higher Productivity Rate

Disadvantages:

• Requires Large Mill Runs / higher total # of pounds
