Machinability


 
Machinability is a key factor in increasing productivity.  With Alcoa’s cold finished aluminum and screw machine stock, productivity goes up by allowing an increase to the speeds and feeds and also longer tool life.  Efficiency is impacted in reduced downtime due to bird’s nesting around the tools, less chip management and less part distortion.  In addition, the higher the machinability rating, the less manual secondary operations such as deburring are required.
