Description

Brass CAS NO 12597-71-6 is a versatile and widely used copper-zinc alloy known for its excellent machinability, corrosion resistance, and attractive gold-like appearance. This material is critical for manufacturing durable, reliable components across numerous engineering and decorative applications. It is an essential raw material for industries including plumbing, electrical hardware, musical instruments, and architectural fittings.

Application

• Plumbing Fittings & Valves: Used in the production of corrosion-resistant pipes, faucets, connectors, and ball valves due to its excellent water resistance and machinability.
• Electrical & Electronic Components: Serves as a key material for terminals, connectors, sockets, and switchgear components, offering good conductivity and mechanical strength.
• Architectural Hardware & Decoration: Employed in door handles, locks, hinges, railings, and decorative trims, valued for its aesthetic appeal and tarnish resistance.
• Automotive & Marine Engineering: Utilized in radiator cores, bushings, bearings, marine fittings, and instrument components where resistance to corrosion and wear is paramount.
• Musical Instruments: A primary material for wind instruments such as trumpets, trombones, and saxophones, prized for its acoustic properties and workability.
• Industrial Machinery: Fabricated into gears, wear plates, and custom machined parts that require a combination of low friction, durability, and non-sparking properties.

Quality Control

Our Brass alloys are produced under strict quality management protocols to ensure consistent composition, mechanical properties, and dimensional accuracy. We adhere to relevant international standards such as ASTM, EN, and JIS. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing chemical composition (e.g., Cu, Zn, Pb, Fe content), mechanical properties (tensile strength, hardness), and physical characteristics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). To prevent tarnishing or oxidation, protect from prolonged exposure to moisture, acidic vapors, and saline environments. Keep away from strong acids and ammonia compounds.
