Additional Properties
Corrosion Resistance:
Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Finishes:
#1–Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D–Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B–Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA-Bright annealed cold rolled and bright annealed
#CBA-Course bright annealed cold rolled matte finish and bright anneal
#2-Cold Rolled
#2BA–Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished-Various grit finish for specific polish finished requirements
*Not all finishes are available in all alloys – Contact Shenzhen Sunrise Metal Industry Co.,Ltd 深圳市东升稀有金属有限公司 Sales for more information
