- Excellent cutting performance: cutting resistance only 1/3 that of steel, suitable for high speed machining (cutting speed up to 150-250m/min).
- Strong corrosion resistance: stable in atmospheric and freshwater environments (more than 10 times stronger than steel).
- Good electrical conductivity: electrical conductivity about 60% of pure copper, suitable for electronic components.
- Easy formability: elongation 15-45%, can be cold headed and bent.
- Moderate density: 8.5-8.9g/cm³ (about 110% of steel).
- Environmental differences: lead-containing brass (such as C3604) needs attention to heavy metal pollution, lead-free brass cost is 20-30% higher.

✔ Machining parameter optimization: C3604 is recommended to use coated tungsten carbide tools (TiAlN coating); phosphor bronze processing feed rate needs to be ≤0.15mm/r to prevent tool wear.
✔ Environmental requirements: EU RoHS directive requires lead content ≤0.01%, promoting the application of lead-free brass.
✔ Surface treatment compatibility: beryllium copper is suitable for nickel plating (anti-oxidation); H59 can be antique aged (sulfurization treatment).
✔ Environmental requirements: lead-free brass > H62 > C3604
✔ Machining efficiency: C3604 > Brass 360 > H62
✔ Comprehensive cost: H62 (lowest) < H59 < lead-free brass < C54400 < C17300
