Continuous casting and machine shop

Products and Services

The BOA foundry produces continuously cast bars in copper alloys. Solid round bars, hollow round bars and flat bars, in aluminum and tin bronze alloys. The bars are machined in our in-house workshop to customer specification. On request we produce non-standard alloys and profiles, and centrifugally cast tubes.

Machining

The in-house workshop

At BOA we perform precision mechanical machining to customer specification. We process non-ferrous metals, primarily tin bronzes, aluminum bronzes, brass, and other copper alloys.

Turning
up to Ø 600 mm
Milling
up to 2000 mm in length
CNC machining
machines with up to 5 axes
Metrology room
three-dimensional measuring system and roughness tester
Precision instruments
subject to regular calibration

Made to order

Non-standard, to specification

Centrifugally cast tubes

Rough and machined tubes with an outer diameter greater than 300 mm and a length up to 1000 mm. Actual length and thickness are evaluated based on the total weight of the casting. Every batch is documented: chemical analysis, HB hardness, radiometric testing, tolerances. We supply 3.1 certification in accordance with the standard.

Non-standard alloys and profiles

Alloys based on EU or extra-EU standards and profiles outside the catalogue, produced to customer specification.

Heat treatment and cutting

Additional services on flat bars, to customer specification.

Testing and documentation

Every batch documented

  • Chemical analysis
  • HB hardness
  • Radiometric control

We perform tests for chemical analysis, HB hardness, and radiometric control on all our products. Additionally, we can provide any type of test through our internal laboratory or through qualified external laboratories.

We provide 3.1 certification according to UNI EN 10204 standards.
