High-precision brass strip is a precision-processed brass sheet or strip with strict dimensional tolerances, excellent surface finish and stable mechanical properties. It can be used in various shallow and deep drawing processes, radiator shells, automobile radiators, shells, terminals, connectors, construction, daily decorations, clothing buttons, makeup boxes and other fields.

High dimensional accuracy: The thickness tolerance is usually controlled within ±0.005mm, and the width tolerance is accurate, ensuring the consistency of subsequent stamping, bending and other processing.
Excellent surface quality: The surface is polished or specially treated (such as anti-oxidation coating), with low roughness (Ra≤0.2μm), and no scratches, indentations and other defects.
Stable material performance: Through strict composition control (such as copper-zinc ratio, trace alloy elements) and annealing process, parameters such as hardness, ductility, and conductivity are guaranteed to meet industrial standards.
Optional special performance: Some models have characteristics such as stress corrosion resistance, high elasticity (such as antimony brass C46400) or environmentally friendly lead-free (such as C27000).

4、Key production processes
Continuous rolling: multiple cold rolling passes to control thickness, with annealing in between to eliminate work hardening.
Tension control: ensure strip flatness and avoid warping or edge waves.
Online inspection: laser thickness measurement and surface defect scanners monitor quality in real time.
Electronic appliances: connector terminals (requires high conductivity), shielding covers (requires good electromagnetic shielding).
Precision instruments: gears, watch parts (rely on high dimensional stability).
Automotive industry: sensor components, brake system pipes (requires high corrosion resistance).
Decoration: high-end architectural edging, medals (surface can be plated with gold/silver).
