Quality machined to Perfection

Your satisfaction is our goal:

  • Every rod is inspected individually to ensure the required straightness
  • Diameter tolerances tighter than specified in the norm
  • For rods from 5mm to 65 mm of diameter, the out-of-roundness is residual, deriving from ASBW exquisite drawing process
  • Homogeneity of the surface appearance, mechanical properties and diameter within and across bundles
  • Rod ends shaped to perfectly suit your automated machining process
  • Eddy current test on customer’s request

Precision machining brass rod Details

  • Strict control since raw material selection process ensure high consistency in the alloy properties
  • Refined metallographic structure 
  • Increased lifetime of the tools due to reduced impurity levels, control of alpha and beta phases and lead distribution 
  • Fine chips deriving from homogeneous lead distribution all over the material microstructure

Types of end shaping

By standard, the ASBW machining rod is supplied with pointed and chamfered ends according to EN 12164.
Different combinations of rod ends finishing possible on customers request.


The ASBW precision machining rod is the ideal solution for your production process, offering high quality standards in terms of straightness in its entire length (L1). For round precision machining rods, we offer a gap for the entire deviation of 1 mm/m (h1) and a maximum local deviation of 0,4 mm/ ≤ 400 mm (h2 or h3).


Size range up to 10 mm
The rods are packed loose in a wooden box and protected with oiled paper (net weight of approx. 500 kg). Each box is strapped with 4 steel straps to ensure material integrity during shipping.

Size range above 10 mm 
ASBW machining 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.


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

Quality and environment

ASBW has a certified quality management system in place according to EN ISO 9001:2015 and is committed to its customers in continuously improve the quality of production.

Environment is a concern and global responsibility, to which ASBW is compliant with. ASBW adopts a policy of Social Responsibility, reducing the environmental impact of its activities. Believing in the compatibility between technological progress and environmental preservation, we are licensed at environmental level with APA (Environmental Agency) license number 86120.
