There are two casting considerations. 
1. There are good castings made of superior material specifications.
2. There are junk castings made up of what ever scrap iron was dropped into the melt pot. (Nuts, bolts, old frying pans, engine blocks etc.)

 
 Such a critical piece of steering component should be forged in the first place. If the AMS material specification is correct and the forging process developed the correct grain flow pattern, the control arm probably will never break. 

 I would not worry about any original equipment control arms made by GM. After market chromed is just for show IMHO.
