Standard Brass Rod
Overview
Standard Brass Rod is a copper-zinc alloy widely recognized for its versatility in industrial applications. It typically contains 60-70% copper and 30-40% zinc, with trace elements like lead to enhance machinability. The material adheres to national or international standards (e.g., GB, ASTM), ensuring consistent quality for B2B buyers. Brass rods are favored for their balanced properties, including strength, ductility, and resistance to wear. They are available in various diameters and lengths, catering to specialized needs in machining, forging, and fabrication. The alloy's golden appearance also makes it suitable for decorative uses.
Physical and Chemical Properties
Standard Brass Rod exhibits a density of 8.4-8.7 g/cm³, making it relatively lightweight for metal applications. Its melting point ranges between 900-940°C, depending on the zinc content. The alloy is insoluble in water and resistant to corrosion from moisture, though prolonged exposure to acidic or saline environments may cause tarnishing. Key mechanical properties include a tensile strength of 300-500 MPa and excellent thermal conductivity. The addition of lead (1-3%) in free-machining brass grades (e.g., C36000) improves chip-breaking during CNC operations, reducing tool wear.
Main Applications
In manufacturing, brass rods are precision-machined into valves, fittings, and gears due to their low friction and anti-sparking qualities. The construction sector uses them for architectural hardware and plumbing fixtures, leveraging their corrosion resistance. Electrical applications include terminals and connectors, where conductivity (approximately 28% IACS) is critical. Decorative uses range from musical instruments to furniture accents, often with polished or lacquered finishes.
Safety and Storage
While brass is generally safe to handle, machining generates fine dust that may irritate respiratory systems. Use local exhaust ventilation and PPE like N95 masks. The alloy is non-flammable but should be kept away from strong oxidizers. Store rods in a dry environment with relative humidity below 60% to prevent surface oxidation. Stack horizontally on wooden pallets to avoid bending. For long-term storage, consider anti-tarnish paper or vapor corrosion inhibitors.
B2B Procurement Guide
When sourcing Standard Brass Rod, specify the alloy grade (e.g., C26000 for cartridge brass), diameter tolerance (±0.05mm is common), and straightness requirements. Mill certifications (e.g., EN 10204 3.1) ensure material traceability. Bulk orders (1+ tons) often qualify for 5-10% discounts. Lead times vary by supplier but typically range from 2-4 weeks for custom sizes. Consider partnering with mills that offer just-in-time delivery to reduce inventory costs.
