Description
CDA356 Extra High Leaded Brass is suited to applications where clean machining, stamping, piercing, punching, and blanking are required. Its high lead content supports excellent free-cutting performance, making it useful for components that need repeatable dimensional accuracy.
This alloy offers excellent soldering, good brazing, and a machinability rating of 100. It has poor cold working capacity and fair hot forming capacity, so it is best suited to machined and formed components rather than welded fabrication.
Key Features:
- Extra high leaded brass alloy
- Machinability rating of 100
- Excellent soldering suitability
- Good brazing suitability
- Fair hot forming capacity
- Poor cold working capacity
- Suitable for blanking, machining, piercing, punching, and stamping
- Commonly used for clock components, strip, rod, rolled bar, sheet, and plate applications
