Stamping Rod for Optimum Stamping Results

Tailoring the best Solutions

With the ASBW stamping rod we have achieved to fully meet the compromise between product quality and process efficiency and sustainability.
Optimized rod chemical composition made it possible to answer all the requirements of our customers, being the main distinctive characteristics from the market:

  • Homogeneous properties of the production process and the hot stamped parts;
  • Lower energy consumption due to low stamping temperatures, without compromising an optimum filling of the mould cavities;
  • Enhances process efficiency by minimizing wear of the tool used in hot stamping process and also the surplus material

The ASBW stamping rod therefore makes it possible to achieve optimum results in the manufacture of your stamped parts. 
The ASBW stamping rod is made to order and available in several alloys, being the two best sellers:

  • Standard hot-stamping brass CuZn40Pb2 - ASBW /B13
  • Dezincification-resistant hot-stamping brass CuZn36Pb2As - ASBW / B10

The properties of ASBW / B13 and ASBW / B10 are according with EN 12165.

Stamping Rods Details

Within the entire diameter range of ASBW stamping rods from 11 mm to 95 mm diameter, you will find a tailor-made solution to your production process:

  • Through decades of investigation, development and expertise, it was possible to develop the chemical composition of ASBW stamping rods, specifically for the hot-stamping processes of our customers;
  • Guarantee of a uniform rod surface, which enables a consistent and uniform heating of the billets;
  • From 11mm to 65 mm of diameter, all rods are produced in the drawn condition, in order to ensure tight diameter tolerances that allows lower process waste rates, greater precision when the billets are being cut to length, therefore being ideal for fully automated production processes;
  • Tighter tolerances in rod diameter and length ensure an ideal use of the supplied material, minimizing waste material and maximizing profitability.

To fully meet the requirements of the drinking water standard 4 MS Common Composition List, ASBW has a wide range of solutions:

* Restrictions to the chemical composition according to 4 MS Common Composition List, for drinking water applications.

** Dezincification resistance is achieved through a β-phase-free microstructure. Therefore, a 550 °C/4h heat treatment of the parts is recommended after stamping.

**** Internal Designation.

Furthermore, ASBW offers different products for the most demanding and specific applications:

  • ASBW / B14 - for parts demanding extensive machining after the hot stamping process
  • ASBW / B22 and ASBW / B23 – low lead, high-strength and excellent machinability brass
  • ASBW / B09 - for parts that are subjected to cold forming after the hot stamping process

The ASBW stamping rod is supplied in the drawn condition for diameters up to 65 mm. For dimensions above 65 mm, the rods are supplied only extruded, not drawn.

The delivery material condition for ASBW hot stamping rod is "M", in accordance with EN 12165, that is without specified mechanical properties.

Recommended stamping temperature range for the most relevant alloys:

  • ASBW / B10       740-850 °C
  • ASBW / B11       640-740 °C
  • ASBW / B13       640-740 °C

One of the most relevant parameters to control in the hot stamping process is temperature. Therefore, an accurate adjustment of the emission coefficient for pyrometer measurement is advised. In the temperature range between 650 and 850 oC, ASBW hot stamping rods have revealed a relatively constant emissivity of 0,68, according to the tests carried out on the different alloys. This value is merely given for reference, attending to variations in measurement from pyrometer to pyrometer.


In order to ensure, the traceability according to NP EN ISO 9001:2015, each bale (wooden box or bundle) is marked with a label indicating the details mentioned below:

  • customer
  • number of customer’s order
  • EN Standard of the material
  • ASBW material code
  • rod length
  • ASBW’s PO number
  • ASBW’s Quality Approval Seal


All ASBW hot stamping rods are supplied by standard in bundles either of approximately 1.000 kg or 500 kg. Different bundle weights are also possible upon costumer’s request. Each bundle is steel strapped three times on cardboard and both ends are protected with litter, to ensure the material integrity during the transportation.
