Brass Round Bar | UNS C36000 | IS 319

UNS C36000 Round Bar Manufacturer, 2.0401 Round Bar Distributor, ASTM B453 Brass Round Bar Exporter, EN CW614N Round Bar Stockist, Brass Round Bar Supplier.

PM Industries manufactures, supplies, and stocks Brass Round Bar in diameters from 3mm to 200mm. Brass is a copper-zinc alloy family, with copper content typically ranging from 55–95% and zinc from 5–45%. The zinc content is what drives the differences in strength, machinability, and corrosion performance between grades. Common grades stocked include free-cutting brass (C36000), naval brass (C46400), red brass (C83600), and leaded brass.

Machinability is the characteristic brass is most known for in manufacturing. Free-cutting brass machines faster than almost any other metal, holds tight tolerances, and produces a clean surface finish. That's why it's the default choice for high-volume screw machine parts, valve bodies, fittings, and precision turned components.

Common brass grades and their strengths:

• Free-cutting brass (C36000): highest machinability rating of any copper alloy, ideal for high-speed machining operations
• Naval brass (C46400): excellent seawater corrosion resistance, used for marine hardware and pump components
• Red brass (C83600): higher copper content, good corrosion resistance, suitable for plumbing and valve applications
• Leaded brass: improved machinability and surface finish for precision turned components

Corrosion resistance varies by grade but is generally good against atmospheric conditions, fresh water, and many chemicals. Naval brass handles seawater exposure well. For plumbing applications, brass also offers antimicrobial properties that inhibit bacterial growth in water systems, which is a practical advantage beyond just corrosion performance.

Electrical conductivity runs approximately 28% IACS for typical brass grades. That's sufficient for connectors, terminals, switch components, and socket parts where moderate conductivity combined with good machinability and formability is the priority.

Industries and typical applications:

• Plumbing and HVAC: valves, fittings, faucet components, pipe fittings
• Electrical and electronics: connectors, terminals, switch components, socket parts
• Marine: pump components, marine fittings, underwater hardware
• Automotive: fuel system components, bushings, bearings, decorative trim
• Musical instruments: trumpets, trombones, saxophones, flutes
• Architectural and decorative: handrails, lighting fixtures, decorative hardware, nameplates

Brass cold works well and can be brazed and welded using standard techniques. The characteristic golden-yellow color polishes to a bright finish, which matters for decorative and architectural applications where appearance is part of the specification.

Bar is available in all common grades across the full diameter range, in bright polished, machined, annealed, descaled, and commercial finish conditions, with full material certification.
