Corrosion Resistance Aluminium Ball , Solid Bearing Balls Sealing Elements Heat Conductivity

 

2.2mm 1.2mm 1.1mm 2.8mm Miniature Solid Aluminum Bearing Balls Aluminum Beads

 

 

Characteristic

(a) Low weight, good electrical and heat conductivity
(b) High corrosion resistance but low mechanical strength
(c) Easlily machined, drilled and tapped

 

Aluminium balls are characterized by good corrosion resistance and hard-wearing properties,

 

and also come with smooth surface finishes.
 

The basic class (1xxx) simply has good wear and corrosion resistance, and come with a minimum aluminium content of 99%.

 

However, they are also aluminium alloys, so traces of iron, magnesium, silicon, and copper will be present.

 

Light balls featured by good corrosion and wear resistance, very good surface finishing.
 
1xxx series alloys are not heat treated. Balls can be provided in the passivated conditions.
 
Applications
Special bearings and valves, sealing elements (crushed balls), they are used in automotive industry (safety devices), aviation and aerospace industry, electronic industry, welding processes.
