  Dear friends! thank you so much for helping me learning.
  My electrical overhead stirring/mixing is very good for lab. stirring rods and stirring blades are made from stainless steel. I just increase the amount of cream from 100 gram to 1 kg. Therefore, I need to modified the stirring blades. I cannot find the stainless steel. But, I fight stirring bales made from aluminum and plastic. 
  Aluminum or plastic stirring blades are good or bad?

  Thanks

  Aluminum no. Plastic yes. 

  If some day you decide you want stainless steel have it custom made.

  It really depends on what you are mixing. Since aluminium is attacked by both bases and acids it is not a viable choice. Some plastics, however, are subject to dissolve or degrade in contact with organic solvents - I’m thinking of essential oils and other aromatics. Polycarbonate or Perspex might be OK.
