Brass Rods & Bars (Round/Hex/Square/Flats) | C36000, C37700, C38500, C46400

Name: Brass Rods & Bars
Brand: R V Metal Corporation

Product Overview

Brass bars engineered for repeatable machining, clean forging and consistent mechanical performance

R V Metal Corporation supplies brass rods and bars in round, hex, square and flats for CNC machining, turning parts, forging blanks, electrical fittings, plumbing components, fasteners, architectural hardware and general engineering. Grade selection is application-driven: C36000 is widely used for high-speed machining; C37700 is common for hot forging of fittings and valve bodies; C38500 is often preferred for architectural/structural brass sections; and C46400 (naval brass) is selected where seawater/corrosion resistance is critical. Share drawing + service condition and we’ll align alloy, temper, and standard to your requirement.

FAQ

Common Procurement & Technical Questions

Which brass grade is best for CNC machining: C36000 or C38500?

For pure machining speed and chip breakability, C36000 is typically the go-to. If you need a balance of finish, formability, or lead constraints, other alloys may be better. Tell us your part (drawing), machine type, and compliance requirement and we’ll recommend the right alloy.

Do you supply forging billets / cut lengths for brass fittings?

Yes. We can supply cut lengths and forging-ready stock depending on alloy, size, and tolerance requirement. Share your forging process (hot/cold), die design considerations, and consumption for the best supply plan.

Do you provide MTC (Mill Test Certificate) and traceability?

Yes. We can provide chemistry/mechanical properties (as applicable), heat/lot traceability, dimensional checks and inspection records depending on the product and order requirement.

Can you supply in both metric and imperial sizes?

Yes. We support dimensions in mm and inches on drawings, packing lists and documentation. Share your standard (ASTM/EN/IS) to align tolerance and temper.
