Cold Rolled Plate and Sheet

Nickel alloy cold rolled plates and sheets are high-precision thin flat products processed through cold rolling technology, featuring excellent surface quality, strict dimensional tolerances, and superior mechanical properties. They are widely used in precision instruments, electronic equipment, aerospace, medical devices, food industry, and architectural decoration fields. The nickel alloy cold rolled plates and sheets supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy hot rolled coils through multiple precision processes including multi-pass cold rolling, intermediate annealing, finishing, leveling, and surface treatment. Featuring mirror-like smooth surface, uniform and precise thickness, dense structure, and stable properties, they are specifically designed for precision applications with extremely high requirements for surface quality, dimensional accuracy, and material performance.

Cold Rolled Sheet Types:

1. 2B Finish: Cold rolled, annealed, pickled, skin passed, uniform silver-white surface, suitable for general industry
2. BA Finish: Bright annealed, mirror-like smooth surface, suitable for decoration and high cleanliness requirements
3. 4 Finish: Polished, with polishing grain, suitable for architectural decoration
4. HL Finish: Hairline, with continuous grain, suitable for elevators, home appliances
5. Mirror Finish: Precision polished, high reflectivity, suitable for decoration, reflectors

Surface Quality Inspection

1. Visual Inspection: Inspecting surface under specialized light box for scratches, pits, oxidation, rust spots
2. Roughness Measurement:Measuring surface Ra value using roughness tester

Dimensional Inspection

1. Thickness: Multi-point measurement using high-precision micrometers or laser thickness gauges
2. Width, Length: Measuring using tape measures
3. Flatness: Measuring using surface plates and feeler gauges
