The C77600 nickle silver brass imparts silvery yellow color when sanded or polished. The alloy possess excellent strength and corrosion resistance and is not easy to extrude, thus limited to relatively simple shapes with heavier walls. The “As Extruded” finish of C77600 is gray and further polishing of the alloy reveals the yellow tinted silvery color approaching stainless steel in appearance.
