Round brass bars
Round brass bars are semi-finished products obtained by hot pressing and cold drawing, with excellent turning properties, hot working by pressing (forging), electro-plating, punching and soldering, good resistance to spot welding and less good resistance to electric arc or laser welding.
Brass is resistant to organic substances, neutral or alkaline compounds, but it corrodes easily in an ammonia atmosphere and mechanical stress, and special attention must be paid to dezincification in hot and acidic waters.
COMMON AREAS OF USE FOR ROUND BRASS BARS
- Measuring and control equipment,
- fittings for water and gas installations,
- hardware and locking systems,
- precision mechanical parts,
- watchmaking,
- automotive,
- electrical devices.
