The CW713R brass hollow rods are used to manufacture load-bearing bushings, bearing sleeves and wear-resistant mechanical parts that work under continuous sliding contact.CW713R is a manganese aluminium special brass, CuZn37Mn3Al2PbSi, with high strength and good resistance to surface wear, scoring and galling. It machines at about half the rate of free-cutting brass. The hollow design enables manufacturers to machine bearing surfaces on both the inside and outside, while minimizing unnecessary material removal. USA Piping Solution provides CW713R Brass Hollow Rods in desired sizes with material identification, heat traceability and EN 10204 3.1 mill test certificates. We supply industrial buyers in the USA with material that meets the requirements for precision bushing and bearing production.

Frequently Asked Questions
1. What are CW713R brass hollow rods used for?
CW713R brass hollow rods are used to manufacture bushings, bearing sleeves, wear rings and other sliding mechanical components.
2. What makes CW713R brass suitable for manufacturing bushings?
Its high strength and wear resistance, along with the pre-drilled bore that saves machining time, make it suitable for durable bushings. It machines at about half the rate of free-cutting brass, so tooling should be selected accordingly.
3. What is the difference between CW713R and standard brass alloys?
CW713R contains aluminium, manganese and silicon additions, offering higher strength and wear resistance than conventional brass grades.
4. Is CW713R brass resistant to wear and friction?
Yes, CW713R brass offers good resistance to abrasive wear, galling and scoring in sliding applications.
5. What certificates are supplied with CW713R brass hollow rods?
CW713R brass hollow rods can be supplied with EN 10204 3.1 mill test certificates (MTCs) covering chemical composition and mechanical properties.
6. Is CW713R the same as CZ135?
CZ135 is the British Standard designation associated with CW713R. See our CZ135 Brass Hollow Rods page for the designation guide.
7. What hollow rod sizes are available?
We supply CW713R hollow rods in extruded or cold-drawn forms, with outside diameter, bore and length confirmed against your drawing. Send us your OD, bore, length and quantity, and we will confirm what we can supply.
