Phosphor Bronze Strip

Phosphor Bronze Strip is brought to hardness and thickness values ​​by rolling and annealing processes, washing, annealing and slicing processes are applied.

Altıntel Metal produces phosphor bronze strips in widths of 7 – 470 mm and thicknesses of 0.045 – 3.60 mm using modern continuous casting and cold rolling technologies.
