Aluminum External Pitting

mobiledynamics | Nov 15, 201806:05 PM     4

What's the reverse of aluminum pitting. Best way I can say it is Aluminum Bumps ?

Anyhow, in replacing 2 burner components - I determined the root cause. These pieces are cast aluminum . Anyhow, the bottoms were warped. Also, there were speckles/bumps of raised aluminum as well. I can see how it could warp - just due to venturi nut, pressure, heat. However, maybe someone in the know can best advise. What would cause the surface to have bumps.
