Monel® K500 (Alloy K500) is a Nickel Copper alloy which combines the excellent corrosion resistance of Alloy 400 with the added advantages of greater strength and hardness. The increase in strength and hardness is a result of the precipitation hardening capability gained by the additions of titanium and aluminum.

Refer to NACE (National Associate of Corrosion Engineers) for recommendations.
#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 for all alloys - Contact Ulbrich Sales for more information.
XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications)
Soap - Soap coating on tempered wire to act as lubricant
* Contact Ulbrich Wire for custom finishes.
Monel® KSOO (Alloy KSOO) can be hardened by cold working and by heat treating.
