Dear Mr. Jack Champaigne:

Hello!

We have a wheel which is made by Al alloy, it needs to be shotpeened. It is required to used the ceramic bead to shotpeening the wheel, the intensity is 0.07 ¨C 0.14 mm, ceramic shot diameter is 0.25 mm - 0.42 mm, the coverage is 100% in its manual. Can we use the cast steel shot (shot size : s170) to shotpeening the wheel ? Do you know if it can be exchanged for Cast Steel Shot and Ceramic Bead ?
