Technical specifications:

  • E2

  • Brushing possible on straight and arched surfaces

Application:

  • Decorative items
  • Technical items where a high degree of roughness is required

 

 

Effect on scratches and minor flaws in the surface:

  • Gives a structured surface
  • Removes the naturally forming oxide layer

Structure and appearance after treatment:

  • Fine bands in the direction of brushing
  • Bands vary according to the coarseness of the brush

Suitable alloys:

  • Alloys of aluminium, the most extruded profiles and sheets
  • Where a high lustre is required pure alloys should be used

Light Grinding

Choice of grinding band

We have a grinding band suitable for your grinding needs regardless of application or the physical characteristics of the component.
