The C66800 High Tensile Brass Hollow Rods are manganese silicon brass hollow rods made specifically for use in parts that are subjected to severe mechanical loads, wear, and friction. Classified under the UNS designation C66800, this high-tensile brass alloy is characterized by high tensile strength and good wear resistance in sliding and bearing duty. This alloy is made up of copper combined with additives of manganese and silicon, resulting in an improved load-carrying capability of the item in harsh working environments. Due to their hollow structure, these rods can be easily machined into bushings, sleeves, wear rings, and other cylindrical parts with minimal material wastage. USA Piping Solution supplies C66800 High Tensile Brass Hollow Rods with material traceability and mill test certificates.

Frequently Asked Questions
1. What are C66800 High Tensile Brass Hollow Rods?
C66800 Hollow Rods are high-strength manganese-silicon copper alloy products known for their mechanical strength, wear resistance, and load-bearing capacity.
2. What is the difference between C66800 and conventional brass?
C66800 contains manganese and silicon for higher strength and wear resistance, while conventional brass generally offers better formability and lower mechanical strength.
3. Is C66800 sold as high tensile brass or manganese bronze?
It is sold as a high tensile brass because zinc is the main addition to copper. Manganese and silicon provide added strength. Some suppliers call it manganese bronze, so check the UNS number on your drawing.
4. What is the difference between C66800 and C67000?
C67000 contains aluminum, manganese, and iron additions and has a higher copper range, while C66800 is a manganese-silicon brass. See our C67000 High Tensile Brass Hollow Rods page for the full C67000 data.
5. Are C66800 Hollow Rods suitable for hydraulic components?
Yes, they are used for selected hydraulic components such as bushings, sleeves, and wear-resistant parts.
6. Can C66800 Brass be machined easily?
C66800 is a low-lead alloy, so it does not machine like free-cutting brass. It machines well with sharp carbide tooling, and hollow stock removes the drilling step. Send us your part drawing, and we will suggest the bore and wall thickness.
