Possible dimensions:
thickness 0.05 – 3.00 mm
width 3.00 – 135.00 mm

Our width and thickness 
tolerances surpass normally DIN 
standards.
Even better tolerances are 
available on request.

 


- The degree of hardness may be expressed by: extra-soft, soft, hard and extra-hard
                                                                 Vickers values (HV) are preferable
- Surface conditions are suited to watchmaking requirements.
- State of delivery:

a) Manufactured rolls may have coil diameters between 100 – 600 mm depending on thickness and 

    manufacturing possibilities. For large rolls, the maximum outer diameter is 1000 mm.
b) Fixed lengths may vary between 0.5 – 4 m, with a maximum width of 135 mm.
c) Disk diameters may vary between 14 – 60 mm.

d) Stamped pieces, forced and normal, are possible for the watchmaking industry (stamps must be provided  

    by the client.)
