Brass foil and strip, produced under controlled conditions, are extremely suitable for cold forming. These properties are utilised in general engineering, in the electrical and electronic industries and in many other fields.


Brass types

For our thin and ultra-thin foils we use selected pure alloys only.

CuZn37
(EN: CuZn37 ; UNS: C27200 ; EN: CW 508L (BS: CZ 108) ; ISO: CuZn37)
This alloy shows excellent machinability, good spring properties and has an electrical conductivity of approx. 26 % IACS.

CuZn30
(EN: CuZn30 ; UNS: C26000 ; EN: CW 505L (BS: CZ 106) ; ISO: CuZn30)
Same characteristics and applications as CuZn15; slightly different colour.

Tombak types

CuZn15
(EN: CuZn15 ; UNS: C23000 ; BS: CW 502L (CZ 102) ; ISO: CuZn15)
Tombak with a gold colour, very good for cold forming, suitable for pressing, hammering, embossing.

CuZn12
(not standardized)
Same characteristics and applications as CuZn15; slightly different colour.

CuZn10
(EN: CuZn10 ; UNS: C22000 ; BS: CW 501L (CZ 101) ; ISO: CuZn10)
Similar characteristics and applications as CuZn15 und CuZn12;
different colour.

Other brass alloy and tombak types
are possible on request assuming there is sufficient demand.


Dimensions

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

Thickness range                       Width range*

0.006 mm - 0.010 mm               1 mm - 300 mm
0.00024" - 0.0004"                     0.04" - 11.81"

0.010 mm - 0.100 mm               1 mm - 650 mm
0.0004" - 0.004"                        0.04" - 25.6"

* depending on thickness and quality

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 and hard as rolled.


Surface finish and up-grading

We can adjust the appearance of our foil surfaces from matt to very shiny.


Applications

Our brass foils mainly used as pre-material in industrial applications or as resistance material, heating foils and for etching applications.
