The addition of nickel imparts a silvery-yellow color to these alloys when they are sanded or polished. They offer excellent strength and corrosion resistance. These alloys are difficult to extrude and are limited to relatively simple shapes with heavier walls. The "As Extruded" finish of C77600 is gray, while the C79600 is is a chocolate brown. Polishing of either alloy reveals the yellow tinted silvery color approaching stainless steel in looks. |
