Versatile Applications and Superior MaterialASTM B 135 C 26000 seamless brass tubes are widely used in general engineering, plumbing, electrical, and industrial sectors due to their robust mechanical properties and excellent formability. The low lead content (under 0.05%) ensures suitability for potable water systems and sensitive environments. Their yellowish golden hue enhances both functionality and aesthetic value in diverse mounting scenarios.
Reliable Manufacturing and Packaging StandardsManufactured strictly according to ASTM B 135 standards, these brass tubes undergo quality checks to ensure precise dimensions (0.05 mm tolerance) and uniformity. They are packed using standard export procedures, typically in wooden boxes, to safeguard products during transit and deliveryensuring they reach clients in India and worldwide undamaged and ready for direct use.
FAQs of ASTM B 135 C 26000 70-30 Lead Free Brass:
Q: How are ASTM B 135 C 26000 70-30 Lead Free Brass seamless tubes produced?
A: These seamless tubes are manufactured using solid billets of lead-free C26000 (70-30 brass), which undergo extrusion, drawing, and precision finishing processes. The final product is then polished or smoothed to achieve the desired surface finish in accordance with ASTM B 135 standards.
Q: What benefits does lead-free C26000 brass offer over traditional brass alloys?
A: Lead-free C26000 brass ensures a safer, environmentally friendly solution, particularly for applications involving potable water and sensitive electronics. It has excellent corrosion resistance and mechanical properties, without the health risks associated with higher lead content alloys.
Q: Where can these seamless brass tubes be applied most effectively?
A: These tubes are ideal for general engineering applications, plumbing systems requiring hygienic materials, electrical conduits for efficient conductivity, and various industrial usesthanks to their high strength, ductility (4050% elongation), and superior corrosion resistance.
Q: When should one choose a polished or smooth surface finish for brass tubes?
A: A polished or smooth surface is preferred when aesthetic appeal or reduced friction is required, such as in exposed installations or fluid transport systems. This finish also facilitates easier cleaning and provides an added layer of corrosion resistance.
Q: What is the standard packing method for exporting these brass tubes?
A: For export, the seamless brass tubes are packed in sturdy wooden boxes with protective materials, ensuring they remain undamaged during transit and storage, and comply with international export standards.
Q: How does the manufacturing tolerance of 0.05 mm benefit end users?
A: The tight manufacturing tolerance allows for precise fitting and assembly in engineering and industrial applications, minimizing the need for post-production adjustments or modifications during installation.
Q: What are the available sizes and customization options for these brass tubes?
A: Standard lengths are 3 meters, but customization is available for both length and diameter (2 mm to 90 mm). Weight is also tailored according to size requirements, ensuring a solution that meets specific project needs.
