HRB 54~72 High Precision Balls Good Workability Hard - Wearing Properties

Solid Aluminum Ball Aluminum Baffle Ceiling Aluminum Ball 4mm 6mm 8mm

 

 

Corrosion resistance similar to series 1xxx, better against chlorides and alkaline solutions. Good atmospheric corrosion resistance and against freshwater, seawater, organic acids, aldehydes. All aluminium alloys are subjected to pitting corrosion in presence of chlorides.

 

Aluminium balls are characterized by good corrosion resistance and hard-wearing properties, and also come with smooth surface finishes.

 
Light balls featured by good corrosion and wear resistance, very good surface finishing.
 
5xxx series alloys feature a good workability.
 
Applications
Special bearings and valves, they are used in automotive industry (safety devices), aviation and aerospace industry, electronic industry, welding processes.
