Ceramic Pins Aluminia AL₂O₃(80%)

Aluminia (especially Al₂O₃ 80%) is the most important oxide ceramic material

and very important in our sales program.

Ceramic pins will be used at our applications for

adjustment and fixation in thermostat production process.

Standard: Material: AL₂O₃(80%)

Length: 4,0 bis 25 mm

Other length, material and diameter on request

Diameter: 1,5 bis 4,0 mm

Mechanical. Chemical. Thermic. Electric.

Aluminia is simply in any relation top.

Properties acc. GERMAN INDUSTRIAL STANDARDS

VDE 0035/GERMAN INDUSTRIAL STANDARDS EN 60 672:

excellent hardness
high by the time highest firmness
high by the time very high thermal conductivity
very good electric insulation properties
very high resistance
very high chemical resistance
high by the time highest fireproofness

This strength predestine the material for example to the enjoyment in insulators, pressure proof regulator divide, axes as well as aerials shafts.
