Q1: What is the difference between C35000 and CW612N designations?
A: C35000 is the UNS (Unified Numbering System) designation, while CW612N is the European standard equivalent. Both refer to the same leaded brass alloy composition with identical mechanical properties and applications.

Q2: Can you manufacture non-standard rectangular dimensions?
A: Yes, we specialize in custom dimensions. Our manufacturing capabilities allow for rectangular tubes ranging from 6mm to 800mm in outside dimensions with wall thicknesses from 0.5mm to 120mm.

Q3: What surface finishes are available for architectural applications?
A: We offer multiple finishes including polished, bright, hair line, brushed, mirror, and sand blasted surfaces. Custom finishes can be developed based on project requirements.

Q4: Are these tubes suitable for pressure applications?
A: Yes, when manufactured to appropriate wall thickness and temper specifications. Our tubes can be certified for specific pressure ratings upon request with proper testing documentation.

Q5: What is the lead time for custom orders?
A: Standard custom orders typically require 15-20 production days plus shipping time. Expedited manufacturing options are available for urgent requirements.

Q6: Do you provide material certification?
A: Yes, all shipments include material certification confirming compliance with ASTM C35000/CW612N specifications, including chemical composition and mechanical properties.

Q7: Can these tubes be welded or brazed?
A: Yes, our bronze bars are weldable using standard brass welding techniques. We recommend specific filler materials and procedures based on the application requirements.

Q8: What packaging is used for international shipping?
A: We use waterproof paper wrapping with steel strip reinforcement, followed by wooden crating for sea freight. Special packaging solutions are available for sensitive finishes.
