Seamless brass tubes
Brass is a copper alloy with zinc as the main alloyed metal. All brass alloys have copper and zinc combined, to which small amounts of other minerals are added to produce particular required characteristics.
Our current dimensional production range:
From outside diameter 0.80 mm and wall thickness from 0.1 mm
To outside diameter 18 mm and wall thickness to 2.5 mm
We produce seamless brass tubes in a variety of alloys in coils as well as straight lengths
We hold the following alloys in stock:
| Designation | Material No (old) | Material No. EN | Characteristics and uses |
| CuZn 15 | 2.0240 | CW 502 L | Very good cold forming properties, suitable for pressing, stamping, hammering, punching and flared. Used in the electronic and jewellery industries. Also for finished products, pressure instrumentation, springs and spacers. |
| CuZn 20 | 2.0250 | CW 503 L | |
| CuZn 30 | 2.0265 | CW 505 L | Very good cold forming properties. Musical instruments, flexible hoses and spring components. |
| CuZn 33 | 2.0280 | CW 506 L | Very good cold forming properties especially for flaring, upsetting, rivets, finished metal goods and deep drawing. |
| CuZn 30 AS | - | CW 707 R | Special alloy to suppress dezincification |
| CuZn 36 | 2.0335 | CW 507 L | The standard alloy for deep drawing, spinning, upsetting, thread rolling and bending. Good soldering properties. Rivet tubing, lighting fittings and finished metal goods. |
