FAQs of 70/30 Brass Tubes:
Q: How are 70/30 Brass Tubes manufactured and what finishing options are available?
A: These brass tubes are produced using both seamless and welded techniques, employing the cold-rolled process to achieve precise dimensions and superior mechanical properties. Finishing options include bright, polished, plain, or tailored surface treatments, ensuring suitability for both functional and decorative uses.
Q: What are the main benefits of using 70/30 Brass Tubes in marine and heat exchanger applications?
A: The 70/30 Brass alloy provides exceptional corrosion resistance, especially in saline and moist environments, making it ideal for marine settings and heat exchangers. Its stability and longevity under various temperature and pressure conditions ensure reliable performance over time.
Q: Where are these brass tubes commonly applied, and what standards do they meet?
A: 70/30 Brass Tubes are versatile, frequently utilized in industries such as automotive, plumbing, decorative, electrical engineering, marine, and heat exchangers. They conform to well-known standards like ASTM B135, IS 407, BS 2871, and EN, ensuring compatibility with global industry requirements.
Q: What customization options are available regarding size and length?
A: We provide brass tubes in a wide variety of outer diameters (4100 mm), thicknesses (0.53.0 mm), and lengths (standard 3m, 6m, or customized as needed) to match precise project specifications. This flexibility enables tailored solutions for diverse applications.
Q: How are the tubes packaged, and what is the expected lead time for orders?
A: Packaging options include sturdy wooden boxes, protective bundles, and plastic wrapping to safeguard the tubes during transit. Standard lead time ranges from 2 to 4 weeks, subject to the order size and specific requirements.
Q: What process ensures the electrical conductivity of 70/30 Brass Tubes for electrical applications?
A: The cold rolling and precise alloy composition (70% copper, 30% zinc) maintain the tubes electrical conductivity at 28% IACS, making them suitable for certain electrical and grounding installations while retaining mechanical integrity.
