Cadi Company is an ISO 9001:2015 certified manufacturer and distributor of seam weld wheel blanks and finished wheels using RWMA Copper Alloys.

Cadi Company has:

  • A tailored process for individually hot forging blanks consistent with best metallurgical processes.
  • A proprietary process that yields maximum hardness while maintaining necessary ductility.
  • A metallurgically engineered process that yields optimum grain structure.

 

Cadi weld wheels are made from RWMA Class 2 (C18150 and C18200) and RWMA Class 3 (C18000 and C17510) copper alloys. Cadi Class 2 wheels are specially forged to increase hardness to 75Rb minimum. Wheel blanks are in stock to 30” in diameter. Machined forgings are available for:

  • weld wheels and shafts
  • flash/butt welding arms and dies
  • various arms and platen mounts
  • other custom parts from print

 

Cadi understands the metallurgical issues of seam welding wheel manufacturing. We have applied this knowledge to develop a proprietary process that consistently delivers quality seam welding wheels for demanding applications.
