FAQ
Q1: How does C35600 differ from previous leaded phosphor bronzes like C35300?
A1: C35600 has a higher lead content (2.0–3.0%), providing superior machinability, especially for high-speed machining of precision components.
Q2: Can C35600 be used for high-load bearings and gears?
A2: Yes, it combines excellent wear resistance, fatigue strength, and dimensional stability, making it suitable for bearings, bushings, and gears under heavy loads.
Q3: How does C35600 perform in corrosive environments?
A3: It maintains good corrosion resistance in marine, industrial, and mildly acidic environments. Protective coatings are recommended for highly aggressive conditions.
Q4: Is C35600 suitable for soldering, brazing, or welding?
A4: Brazing and soldering are recommended. Welding is possible with controlled heat to avoid weakening mechanical properties. Post-weld stress relief or annealing is suggested.
Q5: Which forms are ideal for precision springs and gears?
A5: Cold-drawn rods and wires provide superior surface finish, tensile strength, and fatigue resistance, ideal for precision mechanical components.
Q6: What international standards govern C35600 quality?
A6: ASTM B103 (sheet/plate), ASTM B505 (rod/bar), UNS C35600, ISO 4332, with traceability ensured via ISO 9001, SGS, and TUV certifications.
