Metal Spinning Design Guidelines

Metal Spinning Design Guidelines

Metal Spinning Advantages

    • Cold working improves tensile strength
    • Forming process strengthens grain structure
    • Cost advantages over casting or forging
    • Uncomplicated tooling reduces lead times
    • Lower cost, lighter weight parts

Metal Spinning Shapes

  • Symmetrical circular shapes-cones
  • Minimum radii of about 1 to 1.5 times material thickness


  • Church Metal forms material from 24 gage up to 5/16″ thick steel
  • Common Steel: Cold rolled, hot rolled, A36
  • High Strength Steel: Corten, Exten
  • Stainless Steel: 304,316,321,409,430
  • Nickel Based Alloys: Hastelloy, Inconel
  • Copper and Brass
  • Aluminum: O temper, H14, H32, 1100, 6061, 3003, 5052


  • The tighter the tolerances of a part the more time and care needs to be taken to achieve those tolerances. The table shows guidelines for the cost conscious, standard commercial parts and specialized parts.
