Description

Brass CAS NO 63338-02-3 is a versatile copper-zinc alloy widely recognized for its excellent machinability, corrosion resistance, and attractive gold-like appearance. This material is essential for manufacturing durable, high-performance components across numerous engineering and decorative sectors. It is a critical raw material for industries including plumbing, electrical hardware, automotive, and architectural fittings.

Application

• Plumbing Fittings & Valves: Used in the production of corrosion-resistant faucets, connectors, and ball valves due to its excellent water resistance and durability.
• Electrical Components: Serves as a key material for terminals, connectors, and switchgear parts, offering good conductivity and mechanical strength.
• Automotive Parts: Employed in the manufacture of radiator cores, bushings, lock components, and decorative trim for its machinability and wear resistance.
• Architectural Hardware: Ideal for door handles, locks, hinges, and decorative fixtures, providing an aesthetic finish and long service life.
• Marine Engineering: Selected for fittings and fasteners in marine environments because of its superior resistance to saltwater corrosion.
• Musical Instruments: Used in the construction of wind instruments (e.g., trumpets, trombones) and other brassware for its acoustic properties and workability.
• Industrial Machinery: Fabricated into gears, bearings, and wear plates where low friction and good bearing properties are required.
