MACHINABILITY
Aluminium alloys of this and comparable compositions are instead hard to machine, because of their tendency to pull and to the speedy device put on due to their excessive Silicon content. Carbide-tipped equipment with massive rake angles and occasional slicing speeds provide relatively properly consequences whilst slicing lubricant and coolant are employed.
CORROSION RESISTANCE
Aluminium LM6 famous outstanding resistance to corrosion below each regular atmospheric and marine conditions. For the severest conditions, this belongings may be in addition more suitable through anodic treatment.
ANODISING
LM6 may be anodised via way of means of any of the not unusualplace processes, the ensuing movie ranging in color from gray to darkish brown.
