Brass 37700 Hex Bars Manufacturer, Stockist and Exporter
Brass 37700 Hex Bars are a premium copper-zinc alloy widely used in industrial and mechanical applications. Known for their excellent machinability, these bars provide high strength combined with superior corrosion resistance. They are commonly used in valve components, fittings, and gears where durability and precision are critical. The alloy composition ensures uniformity, making it ideal for both CNC machining and forging operations. Brass 37700 offers an optimal balance between hardness and ductility. Its hexagonal shape allows for easy handling, storage, and installation. Manufacturers favor these bars for their consistent performance and long service life.
The chemical composition of Brass 37700 includes copper, zinc, and trace amounts of lead and tin to enhance machinability. Copper content typically ranges around 60–63%, while zinc forms the balance to provide strength and corrosion resistance. Lead addition improves cutting performance during machining, reducing tool wear. These bars demonstrate excellent thermal conductivity, making them suitable for heat exchangers and electrical components. They also exhibit good dimensional stability under varying temperature conditions. Brass 37700 is resistant to dezincification, which ensures longevity in water-based applications. Its mechanical properties make it a reliable choice for high-precision components.
Brass 37700 Hex Bars are widely used in manufacturing mechanical and plumbing components. They are essential in producing valves, pumps, gears, and fasteners. In electrical engineering, these bars serve as conductors and terminal components due to their high conductivity. They are also preferred in marine applications for corrosion resistance. The alloy is suitable for decorative hardware because of its attractive gold-like finish. Aerospace and automotive industries utilize these bars for durable, lightweight components. Brass 37700 provides excellent performance in both industrial and consumer-grade products.

These hex bars are known for superior machinability compared to other brass alloys. They can be cut, milled, and turned with minimal tool wear. Threading, drilling, and shaping operations are highly efficient with Brass 37700. The alloy responds well to cold working and can be easily formed into complex components. Surface finishing is smooth, reducing the need for extensive post-processing. Welding and soldering are feasible, though mechanical fastening is often preferred. Manufacturers value these properties for reducing production time and costs while maintaining high-quality output.
Brass 37700 exhibits excellent tensile strength and hardness, typically around 35–45 ksi tensile strength. Its elongation is sufficient to prevent brittle failure, with values averaging 20–30%. The alloy maintains structural integrity under moderate stress and temperature variations. Shear strength is also significant, making it reliable for load-bearing components. The modulus of elasticity ensures that components retain shape under mechanical pressure. Fatigue resistance allows repeated stress cycles without failure. These mechanical properties make Brass 37700 suitable for a wide range of engineering applications.
One of the most notable features of Brass 37700 Hex Bars is corrosion resistance. The alloy resists oxidation in atmospheric and freshwater conditions. Its resistance to dezincification ensures long-term performance in plumbing systems. Even in marine environments, the material maintains structural and aesthetic integrity. Regular maintenance and protective coatings can further enhance durability. The combination of strength and corrosion resistance makes it ideal for outdoor and industrial applications. Brass 37700’s long service life reduces replacement costs and maintenance requirements.
Brass 37700 Hex Bars are manufactured according to international standards such as ASTM B16/B16M. They are available in multiple diameters and hex sizes to meet diverse industrial requirements. Tolerances are tightly controlled to ensure precise fitting and compatibility with machined components. Surface finishes are uniform, and chemical composition is tested for quality assurance. Bars can be supplied in hot-rolled, cold-rolled, or annealed conditions. Certification and traceability are typically provided to guarantee compliance. These specifications make Brass 37700 Hex Bars a reliable material choice for engineers and manufacturers.
