(copper-tin-alloy)

High spring properties and good corrosion resistance make bronze foil and strip a material requested by the electrical and engineering industry.


Standard type

CuSn6
(DIN: CuSn15 ; UNS: C51900 ; EN: CW 452K (BS: Pb 103) ; ISO: CuSn6)

Other bronze types
Are possible on request assuming there is sufficient demand.


Dimensions

We produce bronze foil and strip in a wide range of thicknesses and widths.

Thickness range                  Width range*

0.020 mm - 0.10 mm            1 mm - 320 mm
0.0008" - 0.004"                    0.04" - 12.6"

* depending on thickness and quality

With sufficient demand it would be possible to enlarge the width range.

Our foils are produced on coils.
Most dimensions are also available as sheet, cut to length, not levelled.
Narrow slit dimensions, mainly in widths below 8 mm (0.32") are available in pancake coils or on traverse wound spools.


Tempers

We are in a position to produce a wide range of tempers depending on thickness and quantity requested. Typical tempers are soft annealed or HV 160 U or HV 180 U.


Surface finish

We can adjust the appearance of our foil surfaces from matt to very shiny.
Surface treatments e.g. tinning, silver plating, we offer on request.


Applications

Bronze foils are used in the electrical and engineering industry, for cutting tools in the diamond industry and as hard solder foils in several other industries.
