Easy-to-Machine High-Strength 642 Bronze
- Yield Strength: 42,000 psi
- Hardness: Rockwell B65 (Soft)
- Temper: HR50
- Heat Treatable: No
- Specifications Met: ASTM B150
A low-lead alternative to 316 bronze, 642 bronze is just as machinable with higher strength. Also called aluminum-silicon-bronze, it's used for valve bodies, gears, and bolts.
