Industrial Grade Brass Circles & Rings – Polished, Brushed & Custom Machined Blanks – Available in Free-Cutting C36000, Cartridge C26000, and Naval Brass C46400 – Standards Include ASTM B36 & ASTM B171.

We are a reliable and ISO 9001:2015 certified manufacturer and exporter of Brass Circles & Rings, offering high-precision components tailored for various sectors including electrical, plumbing, automotive, and decorative industries. These products are manufactured using top-grade raw materials and advanced forming processes, ensuring dimensional accuracy, surface finish, and long-term durability. Our production complies with international quality norms and is backed by mill test certificates (MTC), third-party inspection, and full traceability.

Our Brass Circles & Rings are available in various types such as hot-rolled, cold-rolled, and forged rings, in sizes ranging from 50 mm to 1500 mm diameter and 3 mm to 50 mm thickness. We offer a wide selection of grades including C26000 (Cartridge Brass), C28000 (Muntz Metal), C36000 (Free-Cutting Brass), and C46400 (Naval Brass). These conform to ASTM B36 and ASTM B16 standards. Chemically, brass typically contains 60–70% copper and 30–40% zinc, with mechanical properties including tensile strength of 300–550 MPa, elongation up to 45%, and good hardness depending on temper (soft, half-hard, or hard condition).

Known for excellent machinability, corrosion resistance, and aesthetic appearance, Brass Circles & Rings are widely used in marine fittings, gear components, valves, musical instruments, and architectural hardware. Their high thermal and electrical conductivity, combined with easy formability and polishing capabilities, make them ideal for both functional and decorative use. We cater to global markets with certified quality, competitive pricing, custom size solutions, and on-time delivery.

High-Precision Red Brass, Yellow Brass Circles & Rings – Forged, Machined & Rolled Options Available – Soft to Hard Tempers – OD Range: 10mm–1500mm, Thickness: 1mm–100mm – Ideal for Industrial and Decorative Use.
